The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X100-40 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, 100mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X100-40 is a double-acting, single-rod pneumatic cylinder that puts a 40 mm field-adjustable stroke range at your fingertips via a rear-cap screw. With a 32 mm bore and 12 mm piston rod, it delivers 402 N of push force at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa, making it a compact yet capable actuator for light positioning tasks.
Because the effective stroke can be shortened without swapping the cylinder, commissioning and fine-tuning become far faster. The body length A is 182 mm, and the adjustable air cushion (21 mm) decelerates the piston smoothly at stroke end. The standard PT1/8 port and M10x1.25 rod thread keep integration simple.

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.
Dial in the exact stroke end position during machine build or line commissioning without ordering multiple fixed-stroke cylinders. The 40 mm adjustment range lets technicians fine-tune the stop point on the fly.
Use the adjustable end stop to stage small components precisely before a pick-and-place or assembly operation. The 402 N push force at 0.5 MPa handles light-to-medium part positioning with ease.
As tooling or gripper pads wear over time, the rear adjusting screw can be turned to take up the slack and restore the correct stroke end position, extending the service life of the tooling without mechanical rework.
Step up to the 40 mm bore SCJ40 series if you need more push force—the SCJ40 delivers 628 N at 0.5 MPa. If your application does not require stroke adjustability, the fixed-stroke SC32 is a simpler, slightly shorter alternative. For a direct replacement, match the 32 mm bore, 100 mm nominal stroke, 40 mm adjustment range, PT port thread, and basic mounting style. Note that the SCJ mounting subset excludes FB flange and CA/CB clevis; use FA front flange or LB foot mounting if a bracket is needed.
Adjustable-stroke checklist
At 0.5 MPa, the 32 mm bore generates 402 N of push force and 345 N of pull force (the pull is lower because the 12 mm rod reduces the effective piston area on the return stroke). At the maximum operating pressure of 0.9 MPa, push force reaches 724 N.
Yes, provided the mounting and porting match. The SCJ32 body is slightly longer (A=182 mm) to house the adjusting screw. Ensure the 40 mm adjustment range suits your stroke needs, and note that the SCJ uses the same FA/LB/TC mounting accessories as the SC series, but does not support FB flange or CA/CB clevis mounts.
