The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X160-100STC 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, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X160-100STC is a double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw that provides a 100 mm field-adjustable stroke range. This allows you to fine-tune the end position from the nominal 160 mm down to 60 mm without swapping the cylinder. With a 20 mm rod diameter and a 28 mm air cushion, 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 specific model includes a built-in magnet (S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion (TC) mounting style, supplied with the TCM1 bracket (order code F-SC63TC) to allow the cylinder to pivot during operation. The standard TPU seals and PT ports make it a robust choice for general industrial environments where stroke-end adjustability is critical for commissioning or format changes.

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 a single packaging machine to handle different box sizes. Operators can quickly dial in the correct push stroke for each product run without mechanical stops.
In CNC machining or welding fixtures, the adjustable stroke lets you set the precise clamp engagement point. The 1559 N force at 0.5 MPa provides secure holding, and the screw compensates for part tolerance variations.
Use this trunnion-mounted cylinder to pivot a diverter gate on a conveyor. The adjustable stroke fine-tunes the gate's open angle, while the built-in magnet confirms full-open and full-close positions via sensors.
Choose this SCJ63 when you need the 1559 N push force at 0.5 MPa that a 63 mm bore provides, but also require the ability to dial in the stroke end position. If your force requirement is lower, stepping down to a 40 mm bore (628 N push) saves space and air consumption; for higher force, the 80 mm bore delivers 2513 N push. The 100 mm adjustment range is the largest standard option, ideal for applications with significant wear take-up or multiple product setups.
This cylinder is a direct replacement for another AirTAC SCJ63 with a 160 mm nominal stroke and 100 mm adjust range, matching PT ports and the TC centre trunnion mount. For strokes of this length, ensure the rod is not subjected to high side loads; if lateral forces are present, integrate an external guide rail or consider a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
The push force is 1559 N at 0.5 MPa and 2805 N at the maximum operating pressure of 0.9 MPa. The pull force is slightly lower due to the 20 mm rod area, providing 1402 N at 0.5 MPa.
Yes, if you need the added benefit of stroke adjustability. The SCJ63 shares the same bore, rod size, and mounting interfaces as the SC63. Ensure your replacement matches the 160 mm nominal stroke, PT ports, and that you order the TC centre trunnion mount (F-SC63TC) to match your existing pivoting setup.
