The AirTAC Airtac SC40 Standard Cylinder SC40X90STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 90mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X90STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa, making it a capable mid-range actuator for light pressing, clamping, and sorting tasks. Its 90 mm stroke, combined with a 16 mm diameter piston rod and 21 mm adjustable air cushion, provides smooth deceleration in a compact cycle length.
This variant includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors and ships with a centre trunnion (TC) mount and TCM1 bracket (F-SC40TC). The trunnion allows the cylinder to pivot during operation, ideal for swinging or articulating loads. Seals are standard TPU for a working range of -20 to +70 °C, with PT port threads.

The 90 mm stroke and pivoting trunnion mount allow the cylinder to swing a diverter gate on a conveyor line, reliably sorting packages by weight or barcode data.
Delivers 628 N of clamping force at 0.5 MPa for holding workpieces during light welding or assembly. The magnet enables end-of-stroke sensing for automated cycle start.
Used in life-cycle test stands to apply a consistent linear load. The adjustable cushion protects the 16 mm rod and end caps during high-speed repetitive cycling.
For applications needing more force, stepping up to a 50 mm bore provides 982 N at 0.5 MPa, while a 32 mm bore offers 402 N for lighter, faster cycles. The centre trunnion mount is suited for pivoting applications where the cylinder body must rotate; ensure the pivot axis is aligned to avoid binding.
When replacing this unit, match five key points: 40 mm bore, 90 mm stroke, PT port thread, the TC centre trunnion mounting, and the -S magnet for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series cylinders with the same configuration.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 628 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It directly replaces another AirTAC SC40 cylinder with the same bore, stroke, PT ports, TC mount, and magnet.
