The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X110-30S 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, 110mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X110-30S is a double-acting, single-rod pneumatic cylinder that puts field-adjustable stroke control directly in your hands. Its rear-cap adjusting screw lets you fine-tune the stroke end position by up to 30 mm, making it ideal for commissioning trials, format changeovers, and taking up mechanical wear without swapping the cylinder. With a 20 mm diameter piston rod and PT1/4 ports, this 63 mm bore unit delivers a robust 1559 N of push force at 0.5 MPa.
This model includes a built-in magnet, allowing you to clamp CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for reliable, non-contact position sensing. The body length A(SCJ) is 197 mm, and the integrated air cushion decelerates the piston smoothly at the end of its 110 mm nominal stroke. Operating on 40 µm filtered air, it handles pressures from 0.15 to 1.0 MPa across a standard temperature range of -20 to +70 °C.

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 actuator's end stop by up to 30 mm during machine commissioning without needing to re-plumb or swap out the cylinder, saving significant setup time.
In high-cycle clamping or pressing fixtures, use the rear adjusting screw to periodically take up mechanical slack caused by pad wear, maintaining consistent clamping force without reprogramming.
Quickly adapt the stroke end position for different product sizes on a packaging or assembly line. The built-in magnet provides sensor feedback to confirm the new position is reached.
Choose the SCJ63X110-30S when your application demands a mid-range force output with the flexibility to adjust the stroke end on the machine. If you need more force, stepping up to an 80 mm bore provides 2513 N of push at 0.5 MPa; for a lighter, more compact solution, the 50 mm bore offers 982 N. This adjustable-stroke model is the right choice over a fixed-stroke SC when you anticipate needing to change the end position during setup or over the machine's life. For a direct replacement, match the 63 mm bore, 110 mm nominal stroke, 30 mm adjust range, PT port thread, and the integrated magnet. If your application involves significant side loading, consider adding an external guide rail or switching to a guided cylinder to protect the rod bearings.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. The push force is greater because the single rod reduces the effective piston area on the return stroke. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 2805 N.
Yes, it is a direct dimensional replacement for an SC63X110 cylinder, provided you have clearance for the slightly longer rear adjusting screw housing. You must match the 63 mm bore, 110 mm nominal stroke, PT port thread, and the magnet option (S). The key advantage is gaining the ability to shorten the stroke end by up to 30 mm in the field.
