The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X225-100 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 100 mm range without swapping the cylinder. Ø32mm bore, 225mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X225-100 is a 32mm bore double-acting single-rod cylinder with a 225mm nominal stroke and a 100mm rear adjusting screw range, letting you dial in the exact stroke end without swapping the cylinder. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, rising to 724 N push at the maximum operating pressure of 0.9 MPa, with a 12mm diameter piston rod and PT1/8 ports.
This tie-rod cylinder uses a 21mm air cushion to decelerate the piston and operates on 40µm filtered air at speeds from 30 to 800 mm/s. The body length A(SCJ) is 182 mm, and the standard stroke ceiling for this bore is 1000 mm, so the 225mm stroke is well within standard range. The adjusting screw sets the stroke end position only; it is not a force or speed adjuster.

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 100mm adjustment range lets technicians dial in the exact stroke end position during machine commissioning without cutting or swapping cylinders, speeding up line start-up.
On packaging or assembly fixtures where tooling wears over time, the rear screw can be advanced to compensate for material loss, maintaining consistent part contact without reprogramming.
When a machine runs multiple product sizes, operators can quickly adjust the cylinder stroke end to match the new format, reducing changeover time compared to fixed-stroke cylinders.
Choose the SCJ32X225-100 when you need to fine-tune the stroke end by up to 100mm during commissioning or format changes. If you need more push force, step up to the 40mm bore SCJ40, which provides 628 N push at 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC32 cylinder is a simpler alternative. A direct replacement must match the 32mm bore, 225mm nominal stroke, 100mm adjustment range, PT port thread, and basic mounting style. At this 225mm stroke, rod deflection is minimal under axial loads, but if the application introduces side forces, add an external guide rail to protect the rod bearing.
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.
Yes, if you need the adjustable stroke feature. The SCJ32X225-100 has the same bore, rod diameter, and port size as an SC32, but the body is slightly longer to house the adjusting screw. Ensure the 100mm adjustment range fits your space and that the mounting style matches your existing setup.
