The AirTAC Airtac SC32 Standard Cylinder SC32X70STC is a genuine double-acting standard air cylinder with a Ø32mm bore and 70mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X70STC is a double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at 0.9 MPa). Its 70 mm stroke suits compact clamping and short-transfer tasks where the built-in magnet enables direct barrel-mounted sensor feedback.
This configuration includes a centre trunnion (TC) mount with the TCM1 bracket, allowing the cylinder to pivot during actuation. The 12 mm rod and M10x1.25 thread handle light guided loads, while the 21 mm adjustable air cushion protects end-of-stroke components.

The 70 mm stroke and trunnion pivot suit compact pick-and-place units on assembly conveyors, with magnetic sensors confirming each cycle.
Delivers 724 N at 0.9 MPa for light clamping fixtures. The centre trunnion mount lets the cylinder body swing to self-align with the clamp arm.
Used in small test stands requiring a pivoting actuator. The built-in magnet simplifies stroke-end detection without external brackets.
For higher force, step up to the SC40 (628 N at 0.5 MPa). This trunnion-mounted model is ideal for pivoting applications; ensure the load is guided to prevent side-loading the 12 mm rod. For direct replacement, match the 32 mm bore, 70 mm stroke, PT port, TC mount, and the -S magnet option exactly.
Quick checklist
At 0.5 MPa, it provides 402 N pushing and 345 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N.
Match the 32 mm bore, 70 mm stroke, PT port thread, centre trunnion (TC) mount with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This is a tie-rod design, not an ISO 15552 profile.
