The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X30-10 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, 30mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X30-10 delivers a robust 1559 N of push force at 0.5 MPa, making it a capable actuator for medium-duty industrial tasks. Its 10 mm rear adjusting screw lets you fine-tune the stroke end position on the fly, ideal for commissioning and format changes without swapping the cylinder.
Built on a durable tie-rod design with a 20 mm piston rod and PT1/4 ports, this double-acting, single-rod cylinder includes a 28 mm air cushion for smooth deceleration. The body length is 197 mm, providing a compact yet powerful solution for space-constrained, adjustable-stroke applications.

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.
Fine-tune the end-stop during initial machine setup without mechanical rework. The 10 mm screw adjustment allows operators to dial in the exact stroke length needed for a new process.
Compensate for tooling or gripper wear on a packaging line. The adjustable stroke lets you incrementally extend the piston's reach to maintain consistent part contact over time.
Quickly adapt the cylinder's stroke for different product sizes in a forming or pressing station. A simple screw adjustment replaces the need for multiple fixed-stroke cylinders.
Choose the SCJ63X30-10 when you need field-adjustable stroke end positioning in a 63 mm bore package. If your force requirements increase, stepping up to the 80 mm bore provides 2513 N of push force at the same pressure. For applications needing a fixed, non-adjustable stroke, the standard SC63 series is a direct alternative.
For a like-for-like replacement, match this model with any AirTAC SCJ cylinder of 63 mm bore, 30 mm nominal stroke, a 10 mm adjust range, PT thread, and basic mounting. Ensure the replacement uses the same SCJ adjustable-stroke body to guarantee dimensional interchangeability.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. The maximum push force at the 0.9 MPa operating limit is 2805 N. The pull force is lower due to the 20 mm piston rod area.
A rear-cap adjusting screw limits the piston's retraction stroke end by up to 10 mm. This sets the effective stroke shorter than the 30 mm nominal maximum, allowing field adjustment without changing the cylinder's overall dimensions or mounting.
