The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X175-20 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 20 mm range without swapping the cylinder. Ø32mm bore, 175mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X175-20 is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that provides 20 mm of field-adjustable stroke-end control. With a 32 mm bore and 12 mm rod, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa, suiting light positioning and clamping tasks where the final stop point must be dialled in precisely during commissioning or changeover.
This tie-rod cylinder has a PT1/8 port, M10x1.25 rod thread, and an adjustable air cushion of 21 mm. The body length A is 182 mm for the SCJ series, and the standard stroke range for this bore extends up to 1000 mm, making the 175 mm stroke a standard, readily available option. The default configuration uses a TPU seal, PT threads, and basic mounting without a magnet.

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 extend stroke end position during machine commissioning without swapping cylinders or machining external hard stops, speeding up initial build and debugging.
Adjust the stroke end to compensate for tooling or pad wear over time in light clamping or pressing fixtures, maintaining consistent contact pressure without reprogramming.
Set a precise mechanical stop for small parts on a conveyor or indexing table, allowing quick format changes between product runs with a simple screw adjustment.
Choose the SCJ32X175-20 when a 175 mm stroke is needed but the exact end position requires on-machine fine-tuning within a 20 mm window. If more push force is required, stepping up to the 40 mm bore provides 628 N of push at 0.5 MPa. For applications needing a fixed, non-adjustable stroke, the standard SC series is a direct alternative. A correct replacement must match the 32 mm bore, 175 mm nominal stroke, 20 mm adjust range, PT port thread, and basic mounting style. For strokes of 100 mm or more, ensure the rod is not subjected to excessive side loads; an external guide or a guided cylinder should be considered if the load is not perfectly axial.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force on the extend stroke and 345 N of pull force on the retract stroke due to the 12 mm rod. The maximum push force at 0.9 MPa is 724 N.
A screw in the rear cap mechanically limits the piston's extend stroke end. Turning the screw shortens the effective stroke by up to 20 mm from the nominal 175 mm maximum. It sets the end position only and does not adjust speed, force, or cushioning.
