The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X160-10S 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. Ø80mm bore, 160mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X160-10S is a double-acting, single-rod pneumatic cylinder that puts fine stroke-end adjustment directly on the machine. Its rear-cap screw provides up to 10 mm of adjustment, letting you dial in the exact stopping position without adding external hard stops. With a 25 mm piston rod and PT3/8 ports, this cylinder delivers a robust 2513 N of push force at 0.5 MPa, scaling up to 4523 N at 0.9 MPa.
A built-in magnet is included with this model, allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for reliable, non-contact position sensing. The body length A is 239 mm, and the adjustable air cushion decelerates the piston smoothly at both ends of the 160 mm nominal stroke. This genuine AirTAC component is the go-to choice for commissioning and format-change applications where the stroke needs to be precisely tuned on-site.

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.

| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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.

Fine-tune the end-of-stroke position during initial machine commissioning without machining or re-mounting the cylinder. The 10 mm adjustment screw allows operators to quickly dial in the exact stopping point for grippers, pushers, or clamps.
Quickly adapt to different product sizes on packaging or assembly lines. The adjustable stroke allows a single cylinder to handle multiple formats by simply changing the stroke end, reducing changeover time and the need for multiple fixed-stroke cylinders.
Compensate for mechanical wear in tooling or contact surfaces over time. The rear adjusting screw can be easily advanced to take up slack and maintain precise positioning, extending the effective service life of the machine's tooling.
Choose the SCJ80 when your application requires a field-adjustable stroke end in this force class. If you need a fixed stroke and can forgo the adjustment screw, the standard SC80 cylinder offers the same bore and mounting footprint. For higher force requirements, stepping up to the SCJ100 provides 3927 N of push force at 0.5 MPa. The adjustable stroke is purely mechanical, shortening the stroke end by up to 10 mm; it does not alter the cylinder's force output or speed. For direct replacement, match an SCJ80 with a 160 mm nominal stroke, a -10 adjust range, PT3/8 ports, and the -S magnet option.
Adjustable-stroke checklist
As a single-rod cylinder, push and pull forces are different. At 0.5 MPa, the theoretical push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. These forces are identical to the fixed-stroke SC80 cylinder.
A screw in the rear cap mechanically limits how far the piston can retract, effectively shortening the stroke end by up to 10 mm. The nominal 160 mm stroke is the maximum; you can field-adjust it to any shorter stroke within that 10 mm range. It is not a speed or force control.
