The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X160-75S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 75 mm range without swapping the cylinder. Ø32mm bore, 160mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X160-75S is a 32 mm bore double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end. Its rear-cap screw provides up to 75 mm of adjustment, letting you fine-tune the 160 mm nominal stroke for commissioning or format changes without changing the cylinder. The built-in magnet (-S) allows direct mounting of CMSG/DMSG/EMSG sensors for end-of-stroke detection.
At 0.5 MPa, this cylinder delivers 402 N of push force and 345 N on the pull stroke, while at the maximum operating pressure of 0.9 MPa, push force reaches 724 N. The 12 mm diameter piston rod and M10x1.25 rod thread handle precise positioning tasks, and the 21 mm air cushion at each end provides smooth deceleration. The SCJ body length is 182 mm, making it a compact choice for space-constrained adjustable-stroke applications.

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.

Related types: SC (single rod, fixed stroke), SCD (double rod), SCT (multi-position). SCJ mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The 75 mm adjustment range allows operators to precisely dial in the stroke end position on packaging machinery, accommodating different box sizes or product heights without mechanical stops.
With the built-in magnet, CMSG sensors easily clamp to the tie-rods to confirm cylinder position in sorting gates or diverters, ensuring reliable, repeatable actuation in automated lines.
In light-duty clamping or pressing fixtures, the adjustable stroke compensates for tooling wear or material thickness variation over time, maintaining consistent clamp force without reprogramming.
Select the SCJ32X160-75S when you need a compact, adjustable-stroke actuator with sensor feedback. If your force requirement exceeds 724 N at 0.9 MPa, step up to the 40 mm bore SCJ40 series, which provides 628 N of push force at just 0.5 MPa. For applications where the stroke is fixed and never needs field adjustment, the standard SC32 fixed-stroke cylinder is a more economical choice.
This model is a direct replacement for another AirTAC SCJ32X160-75S cylinder with a PT port, basic mounting, and a magnet. For strokes of 300 mm or more in any SCJ series, evaluate side-loading on the rod; an external guide rail or a guided cylinder may be required to prevent rod bending and ensure long seal life.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum operating pressure is 1.0 MPa, where the theoretical push force is 804 N. The practical maximum at 0.9 MPa is 724 N push.
Only if you need the adjustable stroke feature. The SCJ32 body is slightly longer than the SC32 to house the adjusting screw. Ensure the 75 mm adjustment range and the 182 mm body length fit your machine envelope. The port (PT1/8) and mounting are compatible with SC32 accessories.
