The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X150-30 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 30 mm range without swapping the cylinder. Ø32mm bore, 150mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X150-30 is a 32mm bore double-acting, single-rod cylinder with a rear adjusting screw that provides up to 30mm of field-adjustable stroke-end reduction. At 0.5 MPa it delivers 402 N of push force, making it a compact solution for light clamping, sorting, and feeding tasks where the final stop position must be dialled in precisely during commissioning.
This model features a 12mm diameter piston rod, an M10x1.25 rod thread, and PT1/8 ports. The integral air cushion (21mm) decelerates the piston smoothly, and the 182mm body length A(SCJ) keeps the envelope compact. The stroke is well within the 1000mm maximum standard stroke for this bore.

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.
Adjust the stroke end by up to 30mm on the machine without removing the cylinder, speeding up the final setup of stopper and diverter stations.
Compensate for gradual wear on conveyor stops or pusher pads by incrementally extending the effective stroke via the rear screw.
Set the exact clamp depth for delicate electronic or medical components, where a fixed stroke risks crushing the workpiece.
Step up to the SCJ40 bore for a push force increase to 628 N at 0.5 MPa when the 402 N of this 32mm bore is marginal. If the stroke length must never change after setup, a fixed-stroke SC32X150 cylinder is a simpler, lower-cost alternative. For direct replacement, match an SCJ32X150-30 with PT ports, basic mounting, and no magnet.
At a 150mm stroke, side-loading is minimal, but always ensure the load is guided externally if any radial force is present to prevent premature rod bearing wear.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, it generates 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N.
Yes, the SCJ32X150-30 is a direct dimensional match for an SC32X150 cylinder body. The rear cap includes the adjusting screw, making the overall length slightly longer, but mounting and port locations are identical.
