The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X160-10 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø63mm bore, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X160-10 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, letting you fine-tune the stopping position by up to 10 mm without swapping the unit. With a 63 mm bore and 20 mm rod, it delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa, making it a solid mid-range actuator for tasks that need a precise, repeatable end point.
This adjustable-stroke model shares the same rugged tie-rod construction as the fixed SC series but adds a rear-cap adjusting screw. The 28 mm air cushion at each end decelerates the piston smoothly, and the PT1/4 port and M16x1.5 rod thread keep it compatible with standard AirTAC fittings and rod-end accessories. Its body length A is 197 mm, slightly longer than the fixed-stroke version to house the adjustment mechanism.

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 | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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.

Dial in the exact stopping point on a pressing or staking fixture where tooling wear or part tolerance stack-up requires a 10 mm field adjustment to maintain consistent engagement depth.
Quickly adapt a diverter gate or stop on a packaging line to handle a new box size. The 10 mm screw adjustment lets operators change the stroke end without replacing the cylinder.
During machine build and runoff, use the rear screw to experimentally find the optimal stroke for a clamp or ejector, then lock it in place for production, saving engineering time.
Choose the SCJ63X160-10 when your application needs a 160 mm maximum stroke that can be shortened on the machine by up to 10 mm during commissioning or changeovers. If you need more push force, stepping up to the 80 mm bore provides 2513 N at 0.5 MPa; for a lighter, more compact solution, the 50 mm bore delivers 982 N. For a fixed, non-adjustable stroke, the standard SC63X160 is a direct alternative. As a direct replacement, match the 63 mm bore, 160 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting style.
Adjustable-stroke checklist
A rear-cap screw sets the stroke end position. You can shorten the 160 mm nominal stroke by up to 10 mm in the field. It adjusts the stopping point only, not the cylinder's force or speed.
At 0.5 MPa, the SCJ63X160-10 provides 1559 N pushing force and 1402 N pulling force. At the maximum operating pressure of 0.9 MPa, push force reaches 2805 N.
