The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X150-100TC 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, 150mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X150-100TC is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, providing a 100 mm adjustment range on the nominal 150 mm stroke. The rear-cap adjusting screw lets you fine-tune the retracted position without removing the cylinder, making it ideal for commissioning and format changeovers. With a 20 mm piston rod and PT1/4 ports, this 63 mm bore unit delivers 1559 N of push force at 0.5 MPa.
This TC-configuration model includes a centre trunnion pivot for swinging loads, supplied with the TCM1 mounting bracket. The tie-rod construction offers a 28 mm air cushion for smooth end-of-stroke deceleration. At the maximum operating pressure of 0.9 MPa, the cylinder generates 2805 N of push force, suiting it to medium-duty positioning and clamping tasks where stroke length needs regular on-machine adjustment.

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 initial machine setup without swapping cylinders or machining external hard stops.
Quickly adapt the stroke for different product sizes on a packaging or assembly line by turning the rear adjusting screw, minimizing downtime between production runs.
As tooling or gripper pads wear over time, the stroke end can be incrementally extended to maintain precise contact and consistent cycle performance.
Choose the SCJ63 bore when your application needs roughly 1560 N of push force at standard plant air. If you require more force, step up to the SCJ80 bore, which provides 2513 N at 0.5 MPa; for a lighter, more compact solution, the SCJ50 bore delivers 982 N. The 100 mm adjustment range on this model is the maximum offered, giving you exceptional flexibility to shorten the stroke end for wear take-up or different product sizes.
This cylinder is a direct replacement for another AirTAC SCJ63X150-100TC with a centre trunnion mount and PT ports. If your stroke length is fixed and you do not need field adjustability, a standard SC63X150 cylinder with a TC mount is a simpler, more cost-effective alternative. For applications with high side loads at this 150 mm stroke, consider adding an external guide rail to protect the rod bearing from premature wear.
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 due to the area of the 20 mm piston rod. At the maximum operating pressure of 0.9 MPa, the push force reaches 2805 N.
This specific model (SCJ63X150-100TC) comes with the TC centre trunnion mount. If you need a front flange, you would order the FA variant, such as SCJ63X150-100FA. The mounting is integral to the order code and cannot be changed after purchase.
