The AirTAC Airtac SC40 Standard Cylinder SC40X175STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 175mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X175STC is a double-acting pneumatic cylinder delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 175 mm stroke, combined with a 16 mm diameter piston rod and PT1/4 ports, provides a balanced combination of speed and force for medium-duty linear tasks.
This model features a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (suffix -TC) supplied with the TCM1 bracket (F-SC40TC) to allow the cylinder to pivot during operation. The standard TPU seals offer a reliable operating range of -20 to +70 °C.

Operates swinging gates or diverters on a packaging line, with the trunnion mount allowing the cylinder body to pivot as it extends and retracts.
Provides consistent clamping force in a welding jig, where the pivoting action helps accommodate part variation and the magnet confirms full extension.
Controls a pivoting chute or hopper door on a planter or spreader, with sensor feedback ensuring the gate is fully open or closed.
For applications requiring slightly more force, consider stepping up to the SC50 bore, which provides 982 N of push force at 0.5 MPa. If a lower profile is needed, the SC32 offers 402 N. The centre trunnion mounting is ideal for swinging loads, but ensure the pivot axis is aligned to avoid binding. For a direct replacement, match the 40 mm bore, 175 mm stroke, PT1/4 ports, centre trunnion mount, and the integrated magnet sensor capability.
Quick checklist
At 0.5 MPa (5 bar), it delivers 628 N pushing force and 528 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 1130 N.
The TC suffix designates a centre trunnion mount, which is supplied with the TCM1 bracket for pivoting. If you need a fixed mount, select the basic version without the TC suffix, and use foot (LB) or flange (FA/FB) accessories instead.
