The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X225-30S 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, 225mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X225-30S is a double-acting, single-rod tie-rod cylinder that lets you fine-tune the stroke end position by up to 30 mm via a rear adjusting screw, without removing the cylinder from the machine. Its 12 mm piston rod and M10x1.25 rod thread suit light automation tasks, delivering 402 N of push force at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa.
A built-in magnet allows CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for reliable end-of-stroke detection. The 225 mm nominal stroke is well within the 1000 mm maximum for bore 32, and the 21 mm air cushion at each end decelerates the piston smoothly. The body length A is 182 mm, and the port is PT1/8.

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 30 mm adjustment range lets technicians dial in the exact stop position during machine commissioning without swapping cylinders or machining external hard stops.
Fine-tune the pressing or insertion depth in small-part assembly tools. The 12 mm rod and 724 N max push force handle precise positioning of clips, pins, or connectors.
Adjust the retraction point of a product gate or stop on a conveyor line to accommodate different package sizes, with sensor confirmation via the integrated magnet.
Choose this 32 mm bore when your application needs up to 402 N of push force at standard plant air. If you require more force, stepping up to the SCJ40 series provides 628 N push at 0.5 MPa. For applications where the stroke length is fixed after commissioning, the standard SC fixed-stroke cylinder is a simpler, lower-cost alternative. This SCJ model is a direct replacement for any AirTAC SCJ32 cylinder with a 225 mm nominal stroke, 30 mm adjust range, PT1/8 ports, and a built-in magnet.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. The pull force is lower because the rod reduces the effective piston area on the return stroke.
For a direct dimensional and performance match, the replacement should have the same 32 mm bore, 225 mm nominal stroke, 30 mm adjustment range, and PT1/8 ports. The built-in magnet (-S suffix) must also match if your existing setup uses barrel-mounted sensors.
