The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X350-40 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 40 mm range without swapping the cylinder. Ø32mm bore, 350mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X350-40 is a 32 mm bore double-acting, single-rod pneumatic cylinder with a field-adjustable stroke. A rear-cap adjusting screw lets you shorten the stroke end by up to 40 mm, making it ideal for commissioning trials, format changeovers, and wear take-up without swapping the cylinder. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, using a 12 mm diameter piston rod.
This tie-rod cylinder has a PT1/8 port, an M10x1.25 rod thread, and a 21 mm adjustable air cushion for smooth deceleration. The SCJ body length for this 32 mm bore is 182 mm, slightly longer than a fixed-stroke SC to house the adjusting mechanism. It operates on 40 µm filtered air from 0.15 to 1.0 MPa, with a standard speed range of 30-800 mm/s.

Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Precisely dial in the 350 mm stroke end position by up to 40 mm during initial machine commissioning, eliminating the need for custom-length cylinders or hard stops.
On a packaging line, use the 40 mm adjustment to compensate for gripper pad wear over time, maintaining a consistent pick-and-place position without replacing parts.
Quickly adapt a 350 mm stroke actuator for different product sizes on a small assembly cell by adjusting the rear screw, reducing changeover time between batches.
Choose the SCJ32X350-40 when you need to fine-tune a 350 mm stroke end position by up to 40 mm during setup. If 402 N of push force at 0.5 MPa is insufficient, step up to the 40 mm bore SCJ40 series, which provides 628 N of push force at the same pressure. For applications requiring a fixed, non-adjustable stroke, a standard SC32X350 cylinder is a simpler, more cost-effective alternative. A direct replacement must match the 32 mm bore, 350 mm nominal stroke, 40 mm adjust range, PT1/8 port thread, and basic mounting style. For this 350 mm stroke, be mindful of side loads; use an external guide rail or switch to a guided cylinder if the rod will experience significant lateral force to prevent bending.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N. The pull force is lower due to the 12 mm rod reducing the piston area on the return stroke.
A screw in the rear cap acts as an internal, adjustable end-stop for the piston. Turning the screw changes the stroke end position by up to 40 mm, shortening the 350 mm nominal stroke. It does not adjust the cylinder's force or speed, only its mechanical stopping point.
