The AirTAC Airtac SCJ40 Standard Cylinder SCJ40X100-10S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø40mm bore, 100mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ40X100-10S is a double-acting, single-rod tie-rod cylinder that puts stroke-end tuning directly on the machine. Its rear-cap adjusting screw provides up to 10 mm of fine adjustment, so you can dial in the exact end position during commissioning or format changes without swapping the cylinder. With a 16 mm piston rod and PT1/4 ports, it delivers 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa).
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for reliable end-of-stroke detection. The body length A(SCJ) is 185 mm, and the 21 mm air cushion decelerates the piston smoothly. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed range of 30-800 mm/s, making it a versatile workhorse for light automation tasks.

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 | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 end-stop position by up to 10 mm during machine setup, eliminating the need to shim or reposition the cylinder to achieve the perfect stroke length.
Adjust the push stroke on a conveyor stop gate to handle different product widths, using the 628 N push force to reliably position lightweight components.
The built-in magnet works with CMSG/DMSG sensors to provide precise position feedback, ideal for sorting mechanisms where the stroke end is adjusted for varying part sizes.
Choose the SCJ40 when you need field-adjustable stroke in a compact 40 mm bore. If you require more force, step up to the SCJ50, which provides 982 N of push at 0.5 MPa. For applications where the stroke is fixed and never needs adjustment, the standard SC40 fixed-stroke cylinder is a simpler, cost-effective alternative. This SCJ40X100-10S is a direct replacement for any AirTAC SCJ40 with a 100 mm nominal stroke, 10 mm adjust range, PT ports, basic mounting, and a magnet.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. The maximum push force at the 0.9 MPa operating limit is 1130 N. The pull force is lower because the 16 mm piston rod reduces the effective area on the return stroke.
A screw in the rear cap sets the stroke end position, allowing you to shorten the 100 mm nominal stroke by up to 10 mm. It is a mechanical stop for the piston, not a speed or force controller. The cylinder will not hold its position if air pressure is lost; an external lock is required for load holding.
