Both are tractor hydraulic lift cylinders supplied by Ever-Power for agricultural lift applications in the large-frame 535 mm mounting platform.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">The 100 mm bore places these cylinders at the upper-middle of the 535 mm mounting group \u2014 generating approximately 24% more theoretical extension force than the TF1004.55.8 (90 mm bore) at the same pressure, and approximately 21% less than the TC2104.55JD.010 (110 mm bore). The 40 mm rod is the heaviest rod specification in the 200 mm stroke subgroup, proportioned to suit the higher force loads that a 100 mm bore cylinder handles.<\/p>\n<p style=\"margin: 0; font-size: 15px; line-height: 1.7;\">Ever-Power supplies both TF1204.551.1 and TF1304.55.012 as aftermarket replacement cylinders. If your existing cylinder carries one of these reference numbers, confirm the bore, rod, stroke, and mounting distance match \u2014 and note the specific reference number in your inquiry so the correct variant can be confirmed.<\/p>\n<\/div>\n<\/div>\n<p><!-- WHY TWO MODELS ON ONE PAGE --><\/p>\n<div style=\"background: #eef5fb; border-left: 4px solid #0b3d91; border-radius: 4px; padding: 14px 18px; margin: 0 0 32px 0;\">\n<p style=\"margin: 0 0 6px 0; font-size: 14px; color: #17365d; font-weight: bold;\">Why TF1204.551.1 and TF1304.55.012 share this page<\/p>\n<p style=\"margin: 0; font-size: 14px; color: #243447; line-height: 1.7;\">Both reference numbers correspond to the same physical specification: 100 mm bore, 40 mm rod, 200 mm stroke, 535 mm mounting distance. In agricultural hydraulic cylinder cataloging, different reference numbers with the same core geometry typically indicate application variants \u2014 such as differences in the mounting end connection, port thread specification, or a designation from a specific OEM parts list. Creating two separate pages with identical dimensional content would not serve a buyer trying to understand the product or confirm a replacement. Where dimensions are confirmed identical, one page covering both references \u2014 and directing buyers to specify which number they hold \u2014 gives more useful information than two near-duplicate pages.<\/p>\n<\/div>\n<p><!-- SPECIFICATION TABLE --><\/p>\n<h2 style=\"color: #17365d; font-size: 20px; margin: 0 0 12px 0; border-bottom: 2px solid #dde4ea; padding-bottom: 8px;\">TF1204 \/ TF1304 \u2014 Technical Specifications<\/h2>\n<div style=\"width: 100%; overflow-x: auto; margin: 0 0 32px 0;\">\n<table style=\"width: 100%; border-collapse: collapse; font-size: 14px; min-width: 340px;\">\n<thead>\n<tr style=\"background: #17365d; color: #ffffff;\">\n<th style=\"padding: 10px 14px; text-align: left; font-weight: bold;\">Parameter<\/th>\n<th style=\"padding: 10px 14px; text-align: left; font-weight: bold;\">Value<\/th>\n<th style=\"padding: 10px 14px; text-align: left; font-weight: bold;\">Notes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background: #f5f8fb;\">\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea; font-weight: 600;\">Reference Models<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">TF1204.551.1 \/ TF1304.55.012<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">Same core specification; specify reference number in inquiry<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea; font-weight: 600;\">Bore Diameter<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">100 mm<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">~24% more piston area than 90 mm bore; only 100 mm bore in the 535 mm \/ 200 mm subgroup<\/td>\n<\/tr>\n<tr style=\"background: #f5f8fb;\">\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea; font-weight: 600;\">Rod Diameter<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">40 mm<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">Heaviest rod in the 200 mm stroke subgroup; rod-to-bore ratio 0.40<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea; font-weight: 600;\">Stroke<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">200 mm<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">Same as FT800.55A.012 and TF1004.55.8<\/td>\n<\/tr>\n<tr style=\"background: #f5f8fb;\">\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea; font-weight: 600;\">Mounting Distance<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">535 mm<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">Shared with FT800, TF1004, TC2104, FS2604; pin-center to pin-center retracted<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea; font-weight: 600;\">Extended Length<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">735 mm<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">Pin-center to pin-center at full extension (535 + 200)<\/td>\n<\/tr>\n<tr style=\"background: #f5f8fb;\">\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea; font-weight: 600;\">Applicazione<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">Agricultural tractor hydraulic lift systems<\/td>\n<td style=\"padding: 10px 14px; border-bottom: 1px solid #dde4ea;\">Specify reference number; confirm bore \u2014 unique identifier in the 535 mm \/ 200 mm subgroup<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px 14px; font-weight: 600;\">Supplier<\/td>\n<td style=\"padding: 10px 14px;\">Ever-Power<\/td>\n<td style=\"padding: 10px 14px;\">OEM and aftermarket supply; custom specifications on inquiry<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><!-- 100MM BORE POSITION IN THE 535MM GROUP --><\/p>\n<h2 style=\"color: #17365d; font-size: 20px; margin: 0 0 12px 0;\">100 mm Bore in the 535 mm Platform: Position and Force Context<\/h2>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">The 535 mm mounting group spans bore sizes from 80 mm to 120 mm.

Each 10 mm increment in bore produces a roughly similar percentage increase in force potential throughout this range, because bore area scales with the square of the radius and the increments are evenly spaced.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">At 160 bar reference pressure, the theoretical force increases from approximately 101.8 kN (TF1004) to approximately 125.7 kN (TF1204\/TF1304) \u2014 an additional 23.9 kN, or roughly 2.4 additional metric tonnes of linear force at the rod tip. A machine designed around the 100 mm bore cylinder is calibrated to use this force level through its lift linkage geometry, operating at a specific system pressure and pump output that matches the 100 mm bore&#8217;s area and flow requirements.<\/p>\n<p style=\"margin: 0 0 32px 0; font-size: 15px; line-height: 1.7;\">The fluid volume displaced per full extension cycle increases proportionally: at 100 mm bore, one full 200 mm stroke moves approximately 1,571 cm\u00b3 of fluid (7,854 mm\u00b2 \u00d7 200 mm). That is about 24% more than the TF1004&#8217;s 1,272 cm\u00b3 per cycle, and approximately 56% more than the FT800&#8217;s 1,005 cm\u00b3. The hydraulic pump on a machine using the TF1204\/TF1304 must supply this volume within the cycle time the operator expects for lift speed \u2014 which explains why larger bore cylinders require correspondingly higher-output pumps.<\/p>\n<p><!-- 40MM ROD --><\/p>\n<h2 style=\"color: #17365d; font-size: 20px; margin: 0 0 12px 0;\">40 mm Rod: The Heaviest in the 200 mm Stroke Subgroup<\/h2>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">At 40 mm, the rod on the TF1204\/TF1304 is the largest diameter in the 200 mm stroke subgroup \u2014 5 mm more than the TF1004.55.8&#8217;s 35 mm rod and 8 mm more than the FT800&#8217;s 32 mm rod. The rod-to-bore ratio is 40\/100 = 0.40, matching the FT800&#8217;s ratio and slightly above the TF1004&#8217;s 0.39.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">A 40 mm rod cross-section is approximately 1,257 mm\u00b2 (\u03c0 \u00d7 20\u00b2). The annular area available for retraction in a double-acting configuration is 7,854 \u2212 1,257 = 6,597 mm\u00b2. At 160 bar reference pressure, retraction force is approximately 105.6 kN \u2014 about 84% of extension force. The heavier rod reduces the retraction-to-extension force ratio slightly compared to a thinner rod, but this is a standard characteristic of all hydraulic cylinder designs and does not affect extension performance.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">For buckling resistance, the 40 mm rod at 200 mm stroke has a meaningfully better slenderness ratio than the FT800&#8217;s 32 mm rod at the same stroke. The cross-sectional moment of inertia scales with the fourth power of the radius \u2014 a 40 mm rod has (20\/16)\u2074 = approximately 2.44 times the bending stiffness of a 32 mm rod. At the force levels a 100 mm bore cylinder generates, the heavier rod provides appropriate structural robustness for the axial and side loads the installation may impose.<\/p>\n<p style=\"margin: 0 0 32px 0; font-size: 15px; line-height: 1.7;\">From a replacement perspective: the 40 mm rod means pin diameters, clevis bore dimensions, and end-connection geometry will be larger than on lower-bore cylinders in this range. A 40 mm rod end will not fit a bracket designed for a 35 mm or 32 mm rod without modification. Confirm rod diameter and pin dimensions independently of bore measurement when sourcing a replacement.<\/p>\n<p><!-- DUAL MODEL REFERENCE SECTION --><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1648 size-large\" src=\"https:\/\/ever-powers.com\/wp-content\/uploads\/2026\/09\/TF1204-_-TF1304-Tractor-Hydraulic-Lift-Cylinder-1024x575.webp\" alt=\"TF1204 \/ TF1304  Tractor Hydraulic  Lift Cylinder\" width=\"1024\" height=\"575\" title=\"\" srcset=\"https:\/\/ever-powers.com\/wp-content\/uploads\/2026\/09\/TF1204-_-TF1304-Tractor-Hydraulic-Lift-Cylinder-980x550.webp 980w, https:\/\/ever-powers.com\/wp-content\/uploads\/2026\/09\/TF1204-_-TF1304-Tractor-Hydraulic-Lift-Cylinder-480x270.webp 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><\/p>\n<h2 style=\"color: #17365d; font-size: 20px; margin: 0 0 12px 0;\">TF1204.551.1 vs TF1304.55.012: What the Numbers Tell You<\/h2>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">The two reference numbers \u2014 TF1204.551.1 and TF1304.55.012 \u2014 differ in their prefix codes (TF1204 vs TF1304) as well as their suffix notation (.551.1 vs .55.012). In most hydraulic cylinder part numbering systems used in the agricultural sector, a change in the full model designation \u2014 rather than just a suffix \u2014 typically indicates a distinct production variant or a different OEM application code, even when the core dimensional specification is identical.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">Common reasons for two reference numbers covering the same physical specification include: the cylinder was listed under different part numbers in different machine models&#8217; parts catalogues from the same manufacturer family; the reference number changed across a production revision while the cylinder geometry remained unchanged; or one reference number applies to a base model and the other to an application-specific variant with a minor difference in end connection or port specification that is not captured in the four primary dimensions.<\/p>\n<div style=\"background: #eef5fb; border-left: 4px solid #0b3d91; border-radius: 4px; padding: 14px 18px; margin: 0 0 32px 0;\">\n<p style=\"margin: 0 0 6px 0; font-size: 14px; color: #17365d; font-weight: bold;\">What to do when your part carries one of these numbers:<\/p>\n<p style=\"margin: 0; font-size: 14px; color: #243447; line-height: 1.7;\">Note the exact reference number from the existing cylinder or machine documentation and include it in the inquiry. Measure the bore (100 mm), rod (40 mm), stroke (200 mm), and mounting distance (535 mm) directly from the existing cylinder to confirm the physical specification matches.

Even a small leak past a worn piston seal \u2014 say, 0.1 cm\u00b3\/s \u2014 will cause visible drift because the bore area is large. Isolate the cylinder by capping its ports before attributing drift to the piston seal. If drift stops with ports capped, the leakage is in the control valve or check valve circuit. Continue monitoring the drift rate with load: load-dependent drift (heavy load drifts faster) is more characteristic of internal piston bypass; load-independent drift points toward control valve leakage.<\/p>\n<\/div>\n<div style=\"flex: 1 1 280px; min-width: 0; background: #f5f8fb; border: 1px solid #dde4ea; border-radius: 6px; padding: 16px 18px;\">\n<p style=\"margin: 0 0 6px 0; font-weight: bold; color: #17365d; font-size: 14px;\">Slow lift speed despite adequate pressure<\/p>\n<p style=\"margin: 0; font-size: 14px; line-height: 1.6;\">A full extension cycle on a 100 mm bore, 200 mm stroke cylinder displaces approximately 1,571 cm\u00b3 of fluid. If pressure at the cylinder port is adequate but lift speed is slow, the constraint is flow \u2014 not pressure.

A pump that has lost efficiency, a relief valve set too low, or a significant flow restriction in the circuit will all reduce effective lift capacity before a worn piston seal would.
