First, the MEZ504.55.016 has the longest stroke \u2014 142 mm, compared to the next-longest QY350.59.003 at 140 mm (a 2 mm difference), and 32 mm more than the NF63C. Second, its mounting distance \u2014 362 mm \u2014 is 12 mm longer than the NF63C and 62 mm longer than the 300 mm group. Third, its 30 mm rod is the narrowest among all five, which has implications discussed below. None of the other four cylinders are substitutes for it in a machine designed around its specific geometry.<\/p>\n<p><!-- STROKE SECTION --><\/p>\n<h2 style=\"color: #17365d; font-size: 20px; margin: 0 0 12px 0;\">142 mm Stroke: What the Extra Travel Means in Practice<\/h2>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">A 142 mm stroke gives the piston rod 29% more linear travel than the NF63C&#8217;s 110 mm, and 42% more than the YC504D.55.501&#8217;s 100 mm. In a tractor hydraulic lift application, that additional travel translates directly into a wider range of implement position \u2014 the difference between the lowest and highest position of the lift arms is proportional to the cylinder stroke and the geometric ratio of the linkage.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">Whether that additional travel is useful depends entirely on what the machine was designed to do. A tractor with a lift linkage designed around 142 mm of cylinder travel needs that full stroke to achieve its rated maximum lift height. Fitting a shorter-stroke cylinder \u2014 say, 110 mm \u2014 would reduce the maximum lift height the system can reach, even if the replacement cylinder generates the same force. The implement would not rise as high.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">Conversely, fitting a 142 mm stroke cylinder into a machine designed for 110 mm would push the lift arm 32 mm past its designed endpoint \u2014 potentially past a mechanical travel stop, into a position where the linkage geometry becomes unfavorable, or where the cylinder body contacts the machine frame.<\/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; font-size: 14px; color: #17365d; line-height: 1.7;\"><strong>Practical note for replacement sourcing:<\/strong> If your existing cylinder has a 142 mm stroke and 362 mm mounting distance, neither of the other 63 mm bore cylinders in this range is a direct substitute. The dimensional differences \u2014 particularly in mounting distance \u2014 mean that the bracket geometry on your machine will not align with a shorter or differently-mounted replacement. Measure both stroke and mounting distance before concluding that any 63 mm bore cylinder will fit.<\/p>\n<\/div>\n<p><!-- ROD DIAMETER SECTION --><\/p>\n<h2 style=\"color: #17365d; font-size: 20px; margin: 0 0 12px 0;\">The 30 mm Rod: Load Considerations at Extended Position<\/h2>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">At 30 mm, the MEZ504.55.016 has the narrowest rod among the five 63 mm bore cylinders in this group \u2014 5 mm less than the NF63C (32 mm) and 5 mm less than the YC504D.55.501 (35 mm). The significance of this depends on the application.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">Rod diameter affects two things: compression stiffness (resistance to buckling when the rod is extended under axial compressive load) and side-load resistance (resistance to bending from lateral forces). For a cylinder with a 142 mm stroke, the rod is extended further than on shorter-stroke models, which increases the unsupported rod length and therefore the effective buckling risk under high compressive loads.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">In a well-aligned tractor lift installation where the cylinder operates primarily in compression along its axis \u2014 which is the normal condition \u2014 a 30 mm rod at 142 mm stroke is a design choice made by the original machine manufacturer. It does not indicate a deficiency. What it does mean for replacement sourcing is that the rod-end connection on your machine \u2014 pin diameter, clevis or eye dimensions \u2014 will be sized for a 30 mm rod. A replacement with a 32 mm or 35 mm rod will have a larger end fitting that will not match the original bracket without modification.<\/p>\n<p style=\"margin: 0 0 32px 0; font-size: 15px; line-height: 1.7;\">When the rod shows signs of bending or scoring in service, investigate the cause before replacing the cylinder. A bent rod in a lift cylinder that operates in pure compression usually indicates side loading \u2014 either from misalignment in the mounting, from the linkage geometry operating outside its designed range, or from impact damage. A new cylinder in the same installation with the same misalignment will develop the same problem.<\/p>\n<p><!-- BORE AND FORCE --><\/p>\n<h2 style=\"color: #17365d; font-size: 20px; margin: 0 0 12px 0;\">63 mm Bore: Force Reference<\/h2>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">The 63 mm bore gives a piston face area of approximately 3,117 mm\u00b2 (\u03c0 \u00d7 31.5\u00b2). At a reference pressure of 160 bar, theoretical extension force is in the order of 49.9 kN. This is the same force potential as the other 63 mm bore cylinders in this group \u2014 bore is the common denominator, and it does not change based on stroke or rod selection.<\/p>\n<div style=\"background: #eef5fb; border-left: 4px solid #0b3d91; border-radius: 4px; padding: 14px 18px; margin: 0 0 20px 0;\">\n<p style=\"margin: 0; font-size: 13px; color: #17365d;\"><strong>Engineering Reference Note:<\/strong> Force figures are theoretical calculations based on bore geometry and reference pressure only. They are not rated product specifications. Actual force output depends on the hydraulic system&#8217;s operating pressure, valve restrictions, and line losses. No rated pressure for the MEZ504.55.016 has been confirmed by Ever-Power for publication here.<\/p>\n<\/div>\n<p style=\"margin: 0 0 32px 0; font-size: 15px; line-height: 1.7;\">And \u2014 as with every cylinder in this product family \u2014 theoretical cylinder force is not the same as tractor rated lifting capacity. Hitch lifting capacity depends on lift arm geometry, mechanical advantage ratio, cylinder mounting angle relative to the pivot, and whole-machine design parameters that go well beyond the cylinder&#8217;s bore and the system&#8217;s operating pressure. Brochure-rated lift capacity figures come from standardized machine-level testing, not from bore-area calculations.<\/p>\n<p><!-- VARIANT SECTION --><\/p>\n<h2 style=\"color: #17365d; font-size: 20px; margin: 0 0 12px 0;\">MEZ504.55.016 vs MEZ504.55.016-3: Identifying the Right Variant<\/h2>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">In hydraulic cylinder part numbering, suffixes \u2014 whether numeric like &#8220;-3&#8221; or alphabetic \u2014 typically indicate a variant or revision within a base model family. Common reasons for variant suffixes include differences in the mounting end connection (clevis vs eye, different pin diameter), port location or thread type, surface treatment, minor dimensional revision to fit a specific machine configuration, or an updated seal specification from a production revision.<\/p>\n<p style=\"margin: 0 0 14px 0; font-size: 15px; line-height: 1.7;\">Without confirmed documentation specifying what the &#8220;-3&#8221; suffix designates in this particular part number system, the safest approach for a replacement buyer is to verify the physical details of the existing cylinder that go beyond bore, rod, stroke, and mounting distance \u2014 specifically:<\/p>\n<ul style=\"margin: 0 0 20px 0; padding-left: 22px; font-size: 15px; line-height: 1.9;\">\n<li>End connection type at both ends (clevis, eye, trunnion, or other)<\/li>\n<li>Pin diameter at each end<\/li>\n<li>Clevis width or eye width<\/li>\n<li>Port thread type, size, and location<\/li>\n<li>Whether the cylinder has one or two ports<\/li>\n<li>Any visible markings, casting codes, or stamped identifiers on the cylinder body<\/li>\n<\/ul>\n<p style=\"margin: 0 0 32px 0; font-size: 15px; line-height: 1.7;\">If you are ordering based on the reference number MEZ504.55.016-3 specifically, note the suffix when submitting the inquiry so the correct variant can be confirmed. If you are replacing an unlabeled cylinder and matching purely on dimensions, provide the full measurement set \u2014 the variant distinction will be resolved through the end connection details.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1551 aligncenter\" src=\"https:\/\/ever-powers.com\/wp-content\/uploads\/2026\/08\/Agricultural-tractor-300x190.webp\" alt=\"Agricultural tractor\" width=\"300\" height=\"190\" title=\"\"><\/p>\n<p><!-- REPLACEMENT GUIDE --><\/p>\n<h2 style=\"color: #17365d; font-size: 20px; margin: 0 0 12px 0;\">Measuring for Replacement: MEZ504.55.016 Configuration<\/h2>\n<p style=\"margin: 0 0 12px 0; font-size: 15px; line-height: 1.7;\">This cylinder has the longest stroke and the longest mounting distance among the 63 mm bore group.

Isolate the cylinder by disconnecting hoses and capping its ports. If drift stops, the leak is external to the cylinder. If drift continues, the cylinder&#8217;s internal seals are a more likely source. Slow, consistent drift regardless of load weight often points to the control valve rather than the cylinder.<\/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;\">Rod scoring or surface damage<\/p>\n<p style=\"margin: 0; font-size: 14px; line-height: 1.6;\">A scored rod accelerates seal wear. On a long-stroke cylinder like the MEZ504.55.016, more rod is exposed at full extension, increasing surface area subject to contamination and potential damage. Check that the rod wiper seal is intact \u2014 its job is to exclude field debris from entering along the rod as it retracts.<\/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;\">Cylinder does not reach full extension<\/p>\n<p style=\"margin: 0; font-size: 14px; line-height: 1.6;\">If the lift arm stops before reaching maximum height, check whether the cylinder is reaching its internal stop or whether the lift arm is hitting a mechanical limit. Also check hydraulic fluid level and pump output \u2014 insufficient flow or pressure will prevent full extension under load even with an otherwise intact cylinder.<\/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;\">Jerky or uneven movement<\/p>\n<p style=\"margin: 0; font-size: 14px; line-height: 1.6;\">Air in the hydraulic circuit is a common cause of erratic cylinder motion \u2014 particularly after seal replacement or any work that opened the hydraulic lines.

In aftermarket hydraulic cylinder cataloging, a numeric suffix like &#8220;-3&#8221; typically indicates a production variant or revision within the same base configuration \u2014 often a difference in end connection detail, port specification, or surface finish. Creating two nearly identical product pages for the same physical cylinder adds no value for a buyer.

Common uses include: a revision level (the third design iteration of a base model), a variant designation (a specific mounting end or port configuration within the family), or an application code (a derivative produced for a particular machine or customer). Without confirmed documentation for this specific part number system, the safest approach is to note the suffix in any inquiry and verify the end connection and port details against the existing unit, rather than assuming the base number and the suffixed version are fully interchangeable.<\/p>\n<\/div>\n<\/details>\n<details style=\"border: 1px solid #dde4ea; border-radius: 6px; margin-bottom: 10px; background: #ffffff;\" open=\"open\">\n<summary style=\"padding: 16px 18px; font-weight: bold; color: #17365d; cursor: pointer; font-size: 15px;\">Can I replace the MEZ504.55.016 with a QY350.59.003 (140 mm stroke)?<\/summary>\n<div style=\"padding: 0 18px 16px 18px;\">\n<p style=\"margin: 12px 0 0 0; font-size: 14px; line-height: 1.7;\">No, not as a direct replacement.

The rod diameter also differs: 35 mm on the QY350 versus 30 mm on the MEZ504.

Load drift can originate in the cylinder&#8217;s piston seal, but it is equally common for it to come from internal bypass in the control valve or a leaking check valve in the circuit. To isolate the cylinder: disconnect the hydraulic hoses and cap the cylinder&#8217;s ports. If the drift stops with ports capped, the cylinder is holding and the leak is external to it. If drift continues with ports capped, the cylinder&#8217;s internal seals are the more likely source.
