The AirTAC Airtac SC40 Standard Cylinder SC40X175TC 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 SC40X175TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 175 mm stroke suit mid-range linear actuation tasks where a compact tie-rod body is preferred.
This model features a 16 mm diameter piston rod with M12x1.25 threads and PT1/4 ports. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (F-SC40TC), allowing the cylinder to pivot during operation. Total extended body length is approximately 317 mm.

Pivoting gate or diverter arms on packaging lines, where the centre trunnion mount allows the cylinder body to swing as it extends and retracts.
Pneumatic clamping in woodworking or light metal fabrication jigs, using the 175 mm stroke for part ejection or clamp arm actuation.
Actuating chutes or sorting gates on harvesters and processing equipment, benefiting from the pivoting trunnion mount in tight spaces.
Select the SC40 bore for push forces around 628 N at 0.5 MPa. If your load requires more force, step up to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 bore provides 402 N. The 175 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
For replacement, match five points: 40 mm bore, 175 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting, and the non-magnetic piston (no -S suffix). The centre trunnion mount is ideal for applications where the cylinder body needs to swing through an arc.
Quick checklist
At 0.5 MPa operating pressure, the cylinder provides 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 mount includes a trunnion bracket (TCM1) that clamps around the cylinder body, creating a pivot point. This allows the entire cylinder to swing as the rod extends and retracts, compensating for angular misalignment in the connected load. The mounting kit part code is F-SC40TC.
