Four dimensions describe a cylinder — bore, rod diameter, stroke and closed length — and the one people leave out is closed length, which is what decides whether the replacement physically fits between the pins. Bore and pressure give the push force; the rod reduces the area on the return, so the pull force is always lower, and a cylinder chosen on push alone can be short on the retract stroke where the real work sometimes happens. Rod diameter is not only about tension either: on a long stroke the extended rod is a column under compression and can buckle, which is why a long-stroke cylinder needs a rod sized for stability rather than for load. Then the mounting, because a cylinder that has to swing needs a pivot arrangement and one that is rigidly mounted must not be asked to take side load. For a repair, say whether you want a new cylinder or the seal kit and a rod.
The more of this you send, the closer the first quotation lands.
| Bore diameter | With working pressure, this gives the push force |
|---|---|
| Rod diameter | Sets the pull force and the buckling resistance on long strokes |
| Stroke | Working stroke required |
| Closed length | Pin to pin retracted — this is what decides whether it fits |
| Working pressure | System pressure and the relief setting |
| Mounting | Clevis, trunnion, flange or foot, with the pin diameters |
| Duty and speed | Cycles per hour, and the extend and retract speeds |
| Cushioning | End cushioning where the cylinder reaches the stops at speed |
| Rod finish | Hard chrome, or a coating for coastal or abrasive environments |
| Seal material | Matched to the fluid and the operating temperature |
| Port size and position | Thread type and size, and the port orientation |
| Repair or replace | New cylinder, or a seal kit and rod for an overhaul |
