The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X150-10 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. Ø63mm bore, 150mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X150-10 is a double-acting, single-rod pneumatic cylinder from the AirTAC SCJ adjustable-stroke family, built around a 63 mm bore and a nominal 150 mm stroke. A rear-cap adjusting screw provides 10 mm of field-adjustable range, allowing you to dial in the exact stroke end position during commissioning or changeover. With a 20 mm piston rod and PT1/4 ports, it delivers a push force of 1559 N at 0.5 MPa and up to 2805 N at the maximum operating pressure of 0.9 MPa.
This model uses the standard TPU seal for a -20 to +70 °C operating range and features an adjustable air cushion (28 mm length) for smooth end-of-stroke deceleration. The basic mounting configuration gives you the freedom to pair it with the specific SCJ accessory you need—such as an FA front flange or LB foot mount—without paying for hardware you won't use. Its tie-rod construction keeps it serviceable and robust in general industrial automation tasks.

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.

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.
Use the 10 mm rear screw to precisely dial in a machine's actuator stroke end during initial build, eliminating the need to shim or cut brackets for a perfect fit.
In clamping or pressing fixtures, the adjustable stroke lets operators quickly take up slack caused by pad wear or workpiece tolerance drift, maintaining consistent clamping force without cylinder replacement.
Adjust the stroke end in seconds to accommodate a new product size on a packaging or sorting line, reducing downtime between batches compared to swapping out a fixed-stroke cylinder.
Choose the SCJ63 bore when your application needs roughly 1560 N of push force at standard plant air pressure. If you can work with less force, stepping down to an SCJ50 (982 N push at 0.5 MPa) saves space and air consumption; if you need more, the SCJ80 provides a substantial jump to 2513 N. This 10 mm adjustable range is ideal for fine-tuning an end stop or taking up minor mechanical wear, but if you need a wider adjustment window, consider the same cylinder with a -20 or -30 suffix.
For a direct replacement, match an AirTAC SCJ63 cylinder with a 150 mm nominal stroke, a 10 mm adjust range, PT ports, and the same mounting accessory. If your setup subjects the rod to high side loads at this 150 mm stroke, an external guide rail or switching to a guided cylinder will protect the rod bearing and seals from premature wear. When the stroke length is fixed and will never need in-situ adjustment, the standard SC fixed-stroke cylinder is a simpler, more cost-effective alternative.
Adjustable-stroke checklist
At 0.5 MPa, it produces 1559 N of push force and 1402 N of pull force (the difference is due to the 20 mm rod area). At the maximum operating pressure of 0.9 MPa, push force reaches 2805 N. Always size your cylinder based on the required force at your specific working pressure.
Yes, this is a direct replacement for any AirTAC SCJ63 adjustable-stroke cylinder that has a 150 mm nominal stroke, a 10 mm adjustment range, and PT ports. Ensure your mounting accessory (FA, LB, TC, or basic) and magnet option (S or none) also match your original configuration.
