The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X160-40S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 40 mm range without swapping the cylinder. Ø63mm bore, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X160-40S is a double-acting, single-rod pneumatic cylinder that puts field-adjustable stroke control directly on the machine. Its rear-cap adjusting screw provides up to 40 mm of fine-tuning for the stroke end position, letting you dial in the exact travel needed for commissioning, format changes, or wear compensation without swapping the cylinder. The built-in magnet allows CMSG/DMSG/EMSG sensors to mount directly on the tie-rod barrel for reliable end-of-stroke detection.
With a 63 mm bore and 20 mm rod, this cylinder generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. The PT1/4 ports and M16x1.5 rod thread handle standard pneumatic connections, while the 28 mm adjustable air cushion decelerates the piston smoothly. The body length A(SCJ) is 197 mm, making it a compact solution for applications where the stroke must be precisely set and verified.

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.

The 40 mm adjustment screw allows engineers to precisely dial in the actuator's end-stop on a new assembly line without fabricating custom shims or hard stops, speeding up machine bring-up.
Quickly adapt a pusher or diverter station for a new box size. The operator adjusts the rear screw to change the cylinder's stroke end, eliminating mechanical rework during batch changes.
The built-in magnet enables direct mounting of reed or solid-state sensors. Combined with the adjustable stroke, this creates a flexible clamping station where both the clamp position and its verification are easily configured.
Step up to an 80 mm bore if your application demands more than the 1559 N push force this SCJ63 delivers at 0.5 MPa; the SCJ80 provides 2513 N. For a simpler, fixed-stroke solution where adjustability is not required, the standard SC63 cylinder is a direct alternative. This SCJ63X160-40S model is a precise replacement for another AirTAC SCJ adjustable cylinder with a 63 mm bore, 160 mm nominal stroke, and a 40 mm adjustment range, using PT ports, a basic mount, and a magnet.
At a 160 mm stroke, rod deflection under side load is generally minimal, but for any off-axis force, consider an external guide rail or a guided cylinder to protect the rod bearing and seal from premature wear.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, this single-rod cylinder delivers 1559 N of push force and 1402 N of pull force. The push force is greater because the pull side has a smaller effective piston area due to the 20 mm rod. At the maximum 1.0 MPa operating pressure, the theoretical push force is 3118 N.
Yes, if you need the ability to fine-tune the stroke end. The SCJ63X160-40S has the same bore, port size, and mounting footprint as a fixed-stroke SC63. The key difference is the rear adjusting screw, which lets you shorten the stroke by up to 40 mm. Ensure your machine has clearance for the slightly longer body length A(SCJ) of 197 mm.
