The AirTAC Airtac SCJ250 Standard Cylinder SCJ250X200-10 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. Ø250mm bore, 200mm nominal stroke, PT1" ports and adjustable end cushioning.
The AirTAC SCJ250X200-10 is a robust double-acting, single-rod pneumatic cylinder engineered for heavy-duty applications requiring precise, field-adjustable stroke end positioning. With a substantial 250 mm bore, this model delivers a powerful push force of 24544 N at 0.5 MPa, making it suitable for pressing, clamping, and large-scale material handling tasks. The rear-cap adjusting screw provides a 10 mm range to fine-tune the stroke end, allowing operators to compensate for wear or adjust for different tooling setups without replacing the entire cylinder.
This ISO 6430 class tie-rod cylinder features a 50 mm diameter piston rod, a 1-inch PT port, and an M42x2 rod thread for secure tooling attachment. The body length (A dimension) is 409 mm, and the unit incorporates an adjustable air cushion to decelerate high-inertia loads smoothly at the end of its 200 mm nominal stroke. Operating on filtered air from 0.15 to 1.0 MPa, this standard-configuration model comes with a TPU seal, PT threads, and no magnet, providing a reliable foundation for integration into large-scale automation systems.

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 | 24544 N | 23562 N |
| 0.7 MPa | 34361 N | — |
| Max (@1.0 MPa) | 5006 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.
The 10 mm stroke-end adjustment screw is ideal for precisely dialing in the final position of large press tools or clamps during initial machine setup, eliminating the need for shims.
Delivers 24544 N of push force at 0.5 MPa for secure clamping of large weldments or composite layups, with the adjustable stroke ensuring consistent pressure application as tooling wears.
Acts as a powerful, adjustable end-stop for pallets or heavy components on a conveyor line, where the 10 mm adjustment range allows for quick changeovers between different product sizes.
Select the SCJ250X200-10 when your application demands the highest force output in the SCJ family and the ability to make minor stroke-end adjustments during commissioning or maintenance. If your force requirement is slightly lower, consider stepping down to the 200 mm bore SCJ200 series, which provides 15708 N of push force at 0.5 MPa and a more compact footprint. For applications needing a fixed, non-adjustable stroke, the standard SC250 series is a direct alternative with identical force characteristics.
For replacement, ensure the new cylinder matches the 250 mm bore, 200 mm nominal stroke, 10 mm adjust range, and PT port thread. This model is a basic configuration, so confirm if your application requires a mounting accessory like an FA front flange or TC center trunnion. At this 200 mm stroke length, the piston rod is well-supported, but for applications with significant side loads, an external guide rail or a switch to a guided cylinder is recommended to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, the push force is 24544 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 5006 kgf. The pull force is lower at 23562 N at 0.5 MPa due to the area of the 50 mm piston rod.
A screw mechanism in the rear cap allows you to shorten the stroke end position by up to 10 mm. This is a mechanical adjustment for setting the piston's stopping point, not a speed or force control. It is ideal for fine-tuning the cylinder's travel for different tasks without needing to change the cylinder.
