The AirTAC Airtac AIRTAC SCJ63 Standard Cylinder SCJ63X500-100 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, 500mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X500-100 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, letting you fine-tune the stopping position by up to 100 mm without swapping the unit. Its 63 mm bore generates 1559 N of push force at 0.5 MPa and 2805 N at the maximum operating pressure of 0.9 MPa, while the 20 mm piston rod and 28 mm air cushion deliver controlled deceleration across the full 500 mm nominal stroke.
This tie-rod cylinder uses a rear-cap adjusting screw to shorten the stroke end, making it ideal for commissioning, format changeovers, and wear take-up. The body length A(SCJ) is 197 mm, and the standard PT1/4 ports and M16x1.5 rod thread integrate easily into existing pneumatic circuits. A genuine AirTAC component, it is built for reliable service in industrial automation.

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.
The 100 mm adjustment range allows engineers to dial in the exact stroke end position during machine commissioning without fabricating custom stops or swapping cylinders, speeding up line start-up.
On packaging or assembly lines, the adjustable stroke lets operators quickly reset the cylinder's end position for different product sizes, reducing downtime between batches.
In clamping or pressing applications, the stroke can be incrementally extended over time to compensate for tooling or pad wear, maintaining consistent contact force without mechanical shims.
Choose the SCJ63X500-100 when you need a 500 mm nominal stroke with up to 100 mm of on-machine adjustment. If your force requirement is lower, stepping down to the 50 mm bore (982 N push at 0.5 MPa) saves space and air consumption; for higher force, the 80 mm bore delivers 2513 N push at the same pressure. This model is a direct replacement for another AirTAC SCJ63X500-100 with PT ports and basic mounting.
At a 500 mm stroke, the extended rod is susceptible to side loading and bending. For applications where the load is not perfectly guided, add an external guide rail or consider a guided cylinder to protect the rod bearing and seal from premature wear. If you do not need the adjustable feature, the fixed-stroke SC63X500 is a simpler, more compact alternative.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N (the pull force is lower because the 20 mm rod reduces the effective piston area on the return stroke). At the maximum operating pressure of 0.9 MPa, the push force reaches 2805 N.
Yes, the SCJ63X500-100 shares the same bore, rod size, ports, and mounting accessories as the SC63 series. The SCJ version adds the rear adjusting screw and is slightly longer in body length, so ensure you have clearance for the A(SCJ) dimension of 197 mm. The adjustable stroke is a bonus if you need end-position tuning.
