The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X450-100 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, 450mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X450-100 is a 32 mm bore double-acting single-rod cylinder that lets you fine-tune the stroke end position across a full 100 mm range without removing the unit from the machine. Its 12 mm diameter rod delivers 402 N of push force at 0.5 MPa, and the rear adjusting screw makes commissioning and format changeovers far quicker than swapping fixed-stroke cylinders.
This tie-rod design includes an adjustable air cushion (21 mm) to decelerate the piston smoothly. The body length A(SCJ) is 182 mm plus stroke, and the PT1/8 port keeps the footprint compact. The 450 mm nominal stroke is well within the 1000 mm maximum for the 32 mm bore, so it ships as a standard configuration.

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 100 mm adjustment range allows technicians to dial in the exact stroke end position during initial machine setup without cutting rods or adding external hard stops.
On packaging or assembly lines, operators can quickly reset the stroke end to accommodate different product sizes or pallet patterns, minimizing downtime between batches.
As tooling or gripper pads wear over time, the rear screw can be advanced to restore the precise end-of-stroke position, extending the service life of the tooling.
Choose this 32 mm bore when 402 N of push at 0.5 MPa covers your load and you need the 100 mm field-adjustable stroke window for setup trials or wear take-up. If your force requirement grows, step up to the 40 mm bore (SCJ40, 628 N push at 0.5 MPa) which also offers a longer 1200 mm max stroke. For applications that do not require stroke adjustment, the fixed-stroke SC32 is a simpler alternative.
A direct replacement must match the 32 mm bore, 450 mm nominal stroke, 100 mm adjust range, PT1/8 thread, and basic mounting. At 450 mm stroke, ensure the rod is not subjected to side loads; use an external guide rail or switch to a guided cylinder if lateral forces are present.
Adjustable-stroke checklist
At 0.5 MPa, it generates 402 N pushing and 345 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. The pull force is lower because the 12 mm rod reduces the effective piston area on the return stroke.
It is a direct fit for an AirTAC SCJ32 adjustable-stroke cylinder with a 450 mm nominal stroke, 100 mm adjust range, basic mounting, and PT1/8 ports. Verify that your existing mounting and port thread match, as this model does not include a magnet or alternative mount.
