The AirTAC Airtac SCJ40 Standard Cylinder SCJ40X160-100 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 100 mm range without swapping the cylinder. Ø40mm bore, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ40X160-100 is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that provides up to 100 mm of field-adjustable stroke-end reduction. This allows operators to fine-tune the piston stop position without removing the cylinder or adding external hard stops. With a 16 mm diameter piston rod and PT1/4 ports, it delivers a push force of 628 N at 0.5 MPa, making it a versatile actuator for medium-duty automation tasks where stroke length needs to be dialed in during commissioning or changeover.
The cylinder body length A(SCJ) is 185 mm plus stroke, and it features an adjustable air cushion of 21 mm for smooth end-of-stroke deceleration. The standard operating pressure ranges from 0.15 to 1.0 MPa, with a maximum push force of 1130 N at 0.9 MPa. This model comes in a basic mounting configuration with TPU seals and PT threads, ready to accept the SCJ-specific mounting accessories like FA, LB, or TC trunnion kits.

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 | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 stop position for a clamp or ejector during machine commissioning. The 100 mm adjustment range allows engineers to test multiple positions quickly without fabricating new stops.
Adjust the stroke end to accommodate different box or pallet sizes on a packaging line. Operators can change the pusher stroke from 60 mm to 160 mm in seconds using the rear screw.
Compensate for tooling wear or material thickness variation in pressing or stamping operations. The adjustable stroke lets you advance the end position incrementally to maintain consistent contact force.
Choose the SCJ40X160-100 when you need to precisely set a stroke end point within a 100 mm window, such as for aligning a pusher with varying product sizes. If the 628 N push force at 0.5 MPa is insufficient, stepping up to a 50 mm bore provides 982 N of push force. For applications requiring a fixed, non-adjustable stroke, the standard SC series is a more economical choice. This cylinder is a direct replacement for another AirTAC SCJ40X160-100 with the same bore, nominal stroke, 100 mm adjust range, and PT port thread. When using a basic mount, ensure the cylinder body is properly supported to prevent rod deflection under side loads.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. The maximum push force at the 0.9 MPa operating limit is 1130 N. Because it is a single-rod cylinder, the push force is greater than the pull force due to the rod area on the return side.
Yes, this is a direct dimensional and performance replacement for any AirTAC SCJ40X160-100 cylinder with a 100 mm adjust range and PT ports. Ensure your mounting (basic, FA, LB, or TC) and magnet option (S) match your original configuration.
