Glossary
| Base Pin |
'A' position has the ports at 90 degrees to the pin. 'B' position has the ports in line with the pins. |
| Base | The fixed end of the cylinder. |
| Bore | The internal diameter of the hydraulic cylinder. |
| Clevis | U shaped coupling, with pin holes, intended to accept a male mount in the gap. |
| Closed length | The distance measured between two fixed points, on the tube, and the rod when the rod is fully retracted. |
| Duty cycle | The expected frequency of operation of the cylinder. |
| Gland | Supports the rod and seals the cylinder at the rod end. |
| Open Length | The distance measured between two fixed points, on the tube, and the rod when the rod is fully extended. |
| Phasing | Phasing, or re-phasing cylinders are designed to enable a set of cylinders to be connected in series, and achieve equal rod extension, or retraction across all the cylinders in the set. |
| Pin eye | Male clevis, designed to fit between clevis plates. |
| Piston | Transmits the hydraulic pressure to the rod, to create a pulling or pushing force. |
| Port |
The connection point between cylinder and the system. Port Position 'A' : 90 degrees to the pin. Port Position 'B' : ports in line with the pins. |
| Rod | The internal reciprocating member of the cylinder, connected to the piston at one end. Also referred to as the shaft. |
| SBH | Spherical bearing housing. |
| Stop tube | Internal fixture which limits the stroke, usually used in cylinders over 1200mm stroke to increase the rigidity of the cylinder, by increasing the distance between the gland and piston. |
| Stroke | The linear travel of the piston within the cylinder. |
| Tube | Barrel of the cylinder. The cylinder size is designated by the tubes internal diameter. |
