The AirTAC Airtac SC40 Standard Cylinder SC40X75TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X75TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa), ideal for medium-duty linear tasks requiring a 75 mm stroke. This model features a 16 mm diameter piston rod with an M12x1.25 thread and an adjustable air cushion length of 21 mm for smooth end-of-stroke deceleration.
Equipped with a factory-fitted TC centre trunnion mount (includes TCM1 bracket, order code F-SC40TC), this cylinder is designed to pivot during operation, absorbing side loads in swinging or oscillating mechanisms. The compact tie-rod body measures 142 mm in length, resulting in a total extended length of approximately 217 mm.

The pivoting TC mount allows this 75 mm stroke cylinder to reliably swing diverter gates on packaging conveyors, directing products between lanes with a controlled 628 N push force.
Provides consistent 1130 N clamping force at 0.9 MPa for holding workpieces in automated welding or assembly jigs, with the trunnion mount allowing the cylinder to self-align as the clamp closes.
Operates discharge chutes or flow-control gates on agricultural hoppers and silos, where the centre-trunnion design handles the arcing motion and dusty environments with robust PT1/4 ports.
For higher force requirements in the same footprint, consider stepping up to the SC50 bore which provides 982 N at 0.5 MPa, while the SC32 bore offers a lighter 402 N option for space-constrained applications. The TC centre trunnion mount is essential for applications where the cylinder must pivot; ensure the trunnion pins are aligned precisely to avoid binding.
When replacing an existing cylinder, match these five points: 40 mm bore, 75 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting, and the absence of a magnetic piston. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder produces 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder. For a drop-in replacement, you must match another SC series cylinder with identical bore, stroke, TC mount, and port thread, as the mounting dimensions are not interchangeable with ISO 15552 profiles.
