The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X400-75 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, 400mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X400-75 is a 32 mm bore double-acting single-rod pneumatic cylinder with a rear adjusting screw that provides up to 75 mm of field-adjustable stroke-end reduction. At 0.5 MPa it delivers 402 N push and 345 N pull, suiting light-to-medium positioning and clamping tasks where the exact end point must be dialled in during commissioning or format changes.
The 12 mm diameter piston rod and PT1/8 port thread keep the unit compact, while the 21 mm air cushion decelerates the piston smoothly. With a body length A(SCJ) of 182 mm plus the 400 mm nominal stroke, this tie-rod cylinder fits machines where space is at a premium but stroke fine-tuning is essential.

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.
During machine setup, the 75 mm rear screw lets technicians dial in the exact 400 mm stroke end position without removing the cylinder or adding external hard stops.
On packaging lines, the adjustable stroke compensates for gradual wear on mechanical end stops, maintaining precise product placement over long production runs.
When a machine switches between product sizes, the SCJ32X400-75 allows operators to quickly adjust the cylinder's end position to suit the new format.
Choose the SCJ32 when you need to trim the stroke end by up to 75 mm without swapping the cylinder—ideal for set-up trials or wear take-up on a 400 mm stroke. If the push force is marginal, stepping up to the SCJ40 delivers 628 N push at the same pressure. For applications that never need stroke adjustment, the fixed-stroke SC32 is a simpler, lower-cost alternative.
For a drop-in replacement, match the 32 mm bore, 400 mm nominal stroke, 75 mm adjust range, PT port thread, and basic mounting. At 400 mm stroke, be mindful of side loads on the 12 mm rod; if the load is not guided externally, consider adding a guide rail or switching to a guided cylinder to prevent rod bending.
Adjustable-stroke checklist
At 0.5 MPa the push force is 402 N and the pull force is 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N. Because it is a single-rod cylinder, push force is always higher than pull force.
Yes, if you need field-adjustable stroke. The SCJ32X400-75 matches the 32 mm bore and 400 mm nominal stroke of an SC32, but adds a rear screw that shortens the stroke end by up to 75 mm. Ensure the slightly longer body length fits your machine and that mounting, port thread, and magnet options match.
