The AirTAC Airtac SCJ40 Standard Cylinder SCJ40X60-10S 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, 60mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ40X60-10S is a double-acting, single-rod pneumatic cylinder from AirTAC that integrates a rear-cap adjusting screw, giving you up to 10 mm of field-adjustable stroke-end control on a nominal 60 mm stroke. With a 40 mm bore and 16 mm piston rod, it delivers 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa), making it a capable mid-range actuator for tasks that need fine positional tuning without swapping the cylinder or adding external hard stops.
This model includes a built-in magnet (-S suffix), so standard CMSG, DMSG, or EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. The tie-rod construction, PT1/4 ports, and 21 mm air cushion keep it serviceable and smooth. The SCJ body is slightly longer than a fixed-stroke SC of the same bore—confirm the exact A dimension from the datasheet—but it shares the same mounting accessories from the SCJ subset.

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 retract or extend end position during machine bring-up without re-plumbing. The 10 mm screw adjustment lets technicians quickly dial in the exact stop point for grippers or clamps.
On packaging lines, adjust the stroke end to accommodate different box or product sizes. The SCJ40X60-10S provides a quick mechanical change instead of reprogramming a servo axis for simple push-and-stop tasks.
Compensate for pad or tooling wear in pressing or stamping fixtures. The rear screw can be advanced to maintain consistent contact pressure without replacing the cylinder or adding shims.
Choose the SCJ40 when you need to dial in a precise stroke end during commissioning or changeover, and the 10 mm adjustment range covers your variation. If your force requirement grows, the 50 mm bore SCJ50 delivers 982 N push at 0.5 MPa; if you can accept a fixed stroke and a slightly shorter body, the standard SC40 is a simpler, cost-effective alternative. For replacement, match the bore (40 mm), nominal stroke (60 mm), adjust range (-10), PT thread, and the built-in magnet option (-S). Mounting accessories from the SCJ subset—such as FA front flange or LB foot—use the F-SC40 prefix. This cylinder cannot hold a load without air pressure; if the load must not drift when the valve is centred, add an external rod lock or pilot-operated check valve.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N (the difference is due to the 16 mm single piston rod). At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 1280 N, but the rated working maximum is 0.9 MPa, giving 1130 N of push force.
Yes, if you need the adjustable stroke feature. The SCJ40 shares the same bore, rod diameter, port size, and mounting accessories as the SC40, but the body is slightly longer to house the adjusting screw. Ensure your machine has clearance for the extra length and order the SCJ40 with the same nominal stroke, port thread, and magnet option as your original SC40.
