The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X160-50TC is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 50 mm range without swapping the cylinder. Ø63mm bore, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X160-50TC is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke, giving you up to 50 mm of fine-tuning on the stroke end via a rear-cap screw. With a 63 mm bore, it delivers 1559 N of push force at 0.5 MPa, making it a robust actuator for medium-duty tasks where the final stop position must be dialled in precisely during commissioning or changeovers.
This model comes configured with a centre trunnion (TC) mount, which is ideal for applications requiring the cylinder to pivot. The trunnion bracket (TCM1) is included, and the assembly mounts using the F-SC63TC hardware. The 20 mm rod and PT1/4 ports are standard, and the body length A(SCJ) is 197 mm, providing a compact footprint for its 160 mm nominal stroke.

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.

Quickly adjust the end stop for different product sizes on packaging or filling lines without changing the cylinder, using the 50 mm adjustment range.
Dial in the precise clamping depth or pressing stroke for workpieces with varying thicknesses, ensuring consistent force without over-travel.
Compensate for mechanical wear in linkages or tooling over time by simply turning the rear adjusting screw to restore the original stroke end position.
Step up to an SCJ80 bore if your application needs more than the 2805 N push force this 63 mm bore provides at 0.9 MPa; the SCJ80 delivers 4523 N. For a fixed, non-adjustable stroke, the standard SC63 is a simpler alternative, but you lose the ability to compensate for tooling wear or fine-tune the end position without external hard stops. This SCJ63X160-50TC is a direct replacement for any AirTAC SCJ63 cylinder with the same 160 mm nominal stroke, 50 mm adjust range, PT ports, and TC mount. For this 160 mm stroke, a rigid external guide is recommended if the rod faces significant side loads to prevent bending.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. The maximum push force at the 0.9 MPa operating limit is 2805 N. The push force is greater than the pull force because it is a single-rod cylinder.
No. Like all standard pneumatic cylinders, the SCJ63X160-50TC will not hold its position or a load if air pressure is lost or the valve is centered. The adjustable screw only sets the stroke end, not a lock. You must use a pilot-operated check valve or an external rod brake to safely hold a load without live pressure.
