The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X500-75 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, 500mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X500-75 is a double-acting, single-rod pneumatic cylinder that puts stroke-end tuning directly on the machine. Its rear-cap adjusting screw provides up to 75 mm of field-adjustable stroke reduction, so you can dial in the exact 500 mm maximum stroke without swapping cylinders or adding external hard stops. The 12 mm piston rod and M10x1.25 rod thread handle push forces of 402 N at 0.5 MPa and up to 724 N at the 0.9 MPa maximum operating pressure.
Built on the proven SC tie-rod platform, this 32 mm bore cylinder uses a 21 mm air cushion to decelerate the piston quietly at end of travel. The PT1/8 port and standard TPU seals cover a -20 to +70 °C operating range. With a body length A of 182 mm plus stroke, it fits compact machine envelopes where commissioning trials, format changeovers, or wear take-up demand a repeatable, adjustable end position.

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.
Dial in the exact 500 mm stroke end during machine bring-up. The 75 mm rear screw lets technicians fine-tune the stop position without cutting brackets or re-machining mounts.
Compensate for pad or tooling wear on linear transfer stations. Adjust the stroke end in seconds to maintain precise part placement without replacing the cylinder.
Quickly reset the stroke for different product sizes on packaging or assembly lines. The 32 mm bore provides 402 N of push force for light-to-medium positioning tasks.
Choose the SCJ32 when you need to fine-tune the 500 mm stroke end without redesigning the tooling. If the 402 N push at 0.5 MPa is marginal, stepping up to the SCJ40 delivers 628 N push at the same pressure. For applications that do not require stroke adjustment, the fixed-stroke SC32X500 is a simpler, slightly shorter alternative. When replacing an existing unit, match the 32 mm bore, 500 mm nominal stroke, 75 mm adjust range, PT1/8 port thread, and basic mounting style.
At 500 mm stroke, the 12 mm rod is fully supported inside the barrel, but any external side load must be managed with an external guide or a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
At 0.5 MPa air pressure, the 32 mm bore generates 402 N pushing force and 345 N pulling force. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
Yes, if your current cylinder is an AirTAC SCJ32 with a 500 mm nominal stroke, 75 mm adjust range, PT1/8 ports, and basic mounting. The SCJ is a tie-rod cylinder, not an ISO 15552 profile cylinder, so confirm the body length A of 182 mm plus stroke and the mounting hole pattern match your machine.
