The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X130-100 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. Ø63mm bore, 130mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X130-100 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, letting you fine-tune the working stroke by up to 100 mm without removing the cylinder from the machine. Its 63 mm bore delivers 1559 N of push force at 0.5 MPa (2805 N at 0.9 MPa), while the 20 mm piston rod and 28 mm air cushion provide smooth deceleration for mid-range automation tasks.
This adjustable-stroke model uses a rear-cap screw to set the precise stroke end position, making it ideal for commissioning trials, format changeovers, or compensating for tooling wear. The body length A(SCJ) is 197 mm, and the standard PT1/4 ports accept common pneumatic fittings. A genuine AirTAC component backed by full traceability.

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.
Quickly dial in a different stroke end for each product size on a carton erector or case packer. The 100 mm adjustment range handles a wide family of box heights without changing the cylinder or adding mechanical stops.
Use the rear adjusting screw to take up slack as clamp pads or tooling wear down over thousands of cycles. The 1559 N push force at 0.5 MPa provides secure part holding for machining or assembly.
During machine bring-up, fine-tune the actuator stroke end in seconds to find the optimal position. Once the process is locked in, the lock nut holds the setting, eliminating the need to machine custom stops.
Choose the SCJ63 bore when your application needs roughly 1560 N of push force at standard plant air pressure. If you require more force, step up to the 80 mm bore which provides 2513 N push at 0.5 MPa; for a lighter, more compact solution, the 50 mm bore offers 982 N push. The 100 mm adjustment range on this model is the maximum available, giving you exceptional flexibility to shorten the stroke end for different product sizes or process steps.
This cylinder is a direct replacement for another AirTAC SCJ63X130-100 with PT ports and basic mounting. If your stroke is fixed and you never need to adjust it, a standard SC63X130 fixed-stroke cylinder is a simpler, more economical choice. For applications where the rod takes a side load, add an external guide rail or switch to a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
Because it is a single-rod cylinder, push and pull forces differ. At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N (the rod area reduces the pull force). At the maximum operating pressure of 1.0 MPa, the theoretical push force is 3118 N. Always size your cylinder based on the required force at your specific working pressure.
Yes, if you need the ability to adjust the stroke end. The SCJ shares the same bore, rod, port, and mounting dimensions as the SC series. To replace an SC63X130, order the SCJ63X130-100, ensuring the port thread (PT or G) and any magnet or mounting options match your existing setup. The body is slightly longer to house the adjusting screw mechanism.
