The AirTAC Airtac SC40 Standard Cylinder SC40X170TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 170mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X170TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model is configured with a TC centre trunnion mount (supplied with TCM1 bracket, order code F-SC40TC), allowing the cylinder to pivot during operation. The 170 mm stroke fits neatly into compact machine cycles, and the PT1/4 ports ensure straightforward pneumatic connections.

The centre trunnion mount lets this cylinder pivot smoothly, making it ideal for actuating diverter gates on packaging conveyors where the 170 mm stroke provides a clean sweep.
With 1130 N of clamping force available at 0.9 MPa, this cylinder secures workpieces in CNC fixtures or welding jigs, and the trunnion mount absorbs misalignment.
Designed for pivoting linkages in process machinery, the SC40X170TC handles oscillating motion reliably, with the 21 mm air cushion softening end-of-stroke impact.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N at 0.5 MPa. If space is constrained, the 32 mm bore delivers 402 N. Always match replacement cylinders across five points: bore (40 mm), stroke (170 mm), port thread (PT), mounting accessory (TC centre trunnion), and magnet option (none on this model).
Quick checklist
At 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
This is a direct replacement for any AirTAC SC40X170TC or a tie-rod cylinder matching 40 mm bore, 170 mm stroke, PT1/4 ports, and a centre trunnion mount. It is not dimensionally interchangeable with ISO 15552 profile cylinders.
