The AirTAC Airtac SC32 Standard Cylinder SC32X20STC is a genuine double-acting standard air cylinder with a Ø32mm bore and 20mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X20STC is a compact double-acting pneumatic cylinder delivering 402 N of push force at 0.5 MPa, ideal for short-stroke clamping and ejection tasks. Its 12 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration in a space-efficient tie-rod body with a 140 mm base length.
This model includes a built-in magnet for mounting CMSG/DMSG/EMSG sensors directly on the barrel, plus a centre trunnion (TC) mount with the TCM1 bracket for pivoting applications. It operates on 40 µm filtered air from 0.15 to 1.0 MPa and uses standard PT ports.

The 20 mm stroke and 402 N force at 0.5 MPa are well-suited for fixturing and clamping small components in CNC machining or assembly jigs.
With its centre trunnion mount and magnetic sensor capability, this cylinder is ideal for actuating small diverter gates on packaging or sorting conveyors.
The compact body and sensor-ready design enable precise, short-stroke ejection of vials or test strips in automated laboratory equipment.
Choose the SC32 for light-duty tasks needing up to 724 N at 0.9 MPa. For higher force, step up to the SC40 (628 N at 0.5 MPa). This 20 mm stroke is well within the 1000 mm maximum for bore 32. The TC trunnion mount suits swinging loads; ensure the pivot axis is aligned to avoid side-loading the rod bearing.
For replacement, match bore (32 mm), stroke (20 mm), port thread (PT), mounting accessory (F-SC32TC centre trunnion), and the built-in magnet (-S). This is a genuine AirTAC tie-rod cylinder, not an ISO 15552 profile.
Quick checklist
At 0.5 MPa, the push force is 402 N and pull force is 345 N. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N.
Match five key points: 32 mm bore, 20 mm stroke, PT port thread, centre trunnion (TC) mount with F-SC32TC bracket, and the built-in magnet (-S) for sensors. Verify the tie-rod body length (140 mm + stroke) fits your space.
