The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X130-30STC is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 30 mm range without swapping the cylinder. Ø63mm bore, 130mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X130-30STC puts a 30 mm field-adjustable stroke end into a 63 mm bore tie-rod body, delivering 1559 N push at 0.5 MPa and 2805 N at the 0.9 MPa maximum operating pressure. Its rear-cap screw lets you fine-tune the end position without removing the cylinder, and the 20 mm rod with M16x1.5 thread handles the single-rod force differential where pull is 1402 N at 0.5 MPa.
This model ships with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion (TC) with the TCM1 bracket, ideal for pivoting applications. The 28 mm air cushion decelerates the piston smoothly, and the PT1/4 ports keep plumbing compact. Body length A(SCJ) is 197 mm, making it a drop-in adjustable alternative to a fixed-stroke SC of the same bore.

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 new end-stop position for different product sizes on packaging or filling lines without swapping cylinders, using the 30 mm rear adjustment range.
Adjust the stroke end to maintain consistent clamping force as tooling or fixtures wear, ensuring part quality in CNC machining or assembly cells.
Fine-tune the actuator stroke on new equipment builds or R&D test rigs. The magnet-equipped body provides sensor feedback for precise end-of-stroke confirmation.
Choose the SCJ63X130-30STC when your machine needs a 130 mm nominal stroke that can be shortened by up to 30 mm during commissioning or changeover. 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 delivers 982 N. The centre trunnion mounting suits swinging loads, but if you need a fixed panel mount, consider the FA front flange variant instead.
For applications where the stroke never needs adjustment, the fixed-stroke SC63X130 is a simpler, slightly shorter alternative. Should your load need to be held in position without air pressure, an external rod lock or pilot-operated check valve is required—the air cushion and stroke-adjust screw do not provide any holding function.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. At the maximum operating pressure of 0.9 MPa, push force reaches 2805 N. The pull force is lower due to the 20 mm single rod reducing the piston area on the return stroke.
Yes, this is a direct replacement for any AirTAC SCJ63 adjustable-stroke cylinder with a 130 mm nominal stroke, 30 mm adjust range, PT1/4 ports, centre trunnion (TC) mounting, and a magnet. Verify that the TCM1 bracket matches your existing pivot point and that the M16x1.5 rod thread is correct for your tooling.
