The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X225-40S 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, 225mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X225-40S is a 32 mm bore double-acting, single-rod pneumatic cylinder with a field-adjustable stroke. A rear-cap adjusting screw provides up to 40 mm of stroke-end reduction, letting you fine-tune the 225 mm nominal stroke without swapping the cylinder. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, with a maximum push thrust of 724 N at the 0.9 MPa operating limit.
This model includes a built-in magnet (-S suffix), allowing easy clamping of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for end-of-stroke detection. The 12 mm diameter piston rod features an M10x1.25 thread, and the cylinder uses PT1/8 ports. Its adjustable air cushion is 21 mm long, and the SCJ body length A is 182 mm, making it a compact solution for applications needing on-machine stroke tweaking.

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.
Fine-tune the end position of a compact pick-and-place arm during initial machine setup. The 40 mm adjustment range allows engineers to dial in the exact stroke without needing to order multiple fixed-stroke cylinders for trial and error.
Adjust the stroke end on a small product diverter gate to compensate for gradual wear on a contact pad. The rear screw can be easily accessed to take up the slack, maintaining precise alignment without disassembling the actuator.
Quickly adapt a labeling machine's tamp pad stroke for different product heights. The operator adjusts the rear screw to set a new, shorter stroke for a smaller box format, reducing changeover time significantly.
Choose the SCJ32 when you need a compact, adjustable-stroke cylinder in the 402 N push force class. If your load requires more force, stepping up to the 40 mm bore SCJ40 provides 628 N of push at the same 0.5 MPa pressure. For applications where the stroke is fixed and never needs adjustment, a standard SC32 fixed-stroke cylinder is a simpler, more cost-effective alternative. The direct replacement match is another AirTAC SCJ adjustable-stroke cylinder with a 32 mm bore, 225 mm nominal stroke, a 40 mm adjust range, PT ports, and a built-in magnet.
Adjustable-stroke checklist
The push force is 402 N at 0.5 MPa, 563 N at 0.7 MPa, and reaches a maximum of 724 N at 0.9 MPa. The pull force on the retract stroke is lower due to the single 12 mm rod, providing 345 N at 0.5 MPa.
Yes, this is a direct dimensional and performance replacement for any AirTAC SCJ32 adjustable-stroke cylinder with a 225 mm nominal stroke, a 40 mm adjust range, PT ports, and a magnet. Ensure your mounting style (basic, FA, LB, or TC) and seal material also match your current setup.
