The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X300-75S 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, 300mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X300-75S delivers 402 N of push force at 0.5 MPa, making it a compact workhorse for light automation tasks. Its 75 mm rear adjusting screw lets you fine-tune the stroke end position on the fly, ideal for commissioning or format changes without swapping the cylinder.
This model features a 12 mm diameter piston rod and PT1/8 ports, with a body length A of 182 mm. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for precise end-of-stroke detection, simplifying your control setup.

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-stop position during machine setup without needing to swap out the cylinder, saving significant integration time.
Quickly adjust the stroke for different product sizes on a packaging line, reducing downtime between batches.
Dial in the stroke end to compensate for mechanical wear in tooling or grippers over time, maintaining consistent operation.
Choose this SCJ32 when you need field-adjustable stroke in a 32 mm bore package. If you require more force, step up to the SCJ40, which provides 628 N of push at the same pressure. For applications needing a fixed, non-adjustable stroke, the standard SC series is a simpler alternative. A direct replacement must match the 32 mm bore, 300 mm nominal stroke, 75 mm adjust range, PT ports, and the -S magnet option.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, this cylinder provides 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N.
A rear-cap adjusting screw allows you to shorten the stroke end by up to 75 mm. The 300 mm in the code is the maximum nominal stroke, and the screw lets you reduce it in the field without affecting the cylinder's force output.
