The AirTAC Airtac SC32 Standard Cylinder SC32X390S is a genuine double-acting standard air cylinder with a Ø32mm bore and 390mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X390S is a double-acting pneumatic cylinder with a 32 mm bore and 390 mm stroke, delivering a push force of 402 N at 0.5 MPa (up to 724 N at 0.9 MPa). Its 12 mm diameter piston rod and 21 mm adjustable air cushion provide smooth end-of-stroke deceleration for light automation tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for contactless position sensing. The body length A is 140 mm, making the total extended length approximately 530 mm, ideal for compact machine layouts.

The 390 mm stroke and 402 N push force at 0.5 MPa suit ejecting lightweight plastic or metal parts from assembly fixtures, with the built-in magnet providing sensor feedback for cycle counting.
Operates small diverter gates on packaging conveyors. The adjustable cushion absorbs impact at the end of the 390 mm travel, reducing noise and mechanical shock on the gate mechanism.
Ideal for test-tube handling or sample transfer in laboratory automation. The compact 140 mm body and TPU seals offer reliable operation in clean, room-temperature environments.
For applications needing slightly more force, consider stepping up to the SC40 series, which provides 628 N at 0.5 MPa. At a 390 mm stroke on a 12 mm rod, side loads must be minimized; if the load is not perfectly guided, use an external linear guide or a guided cylinder to prevent rod bending and premature seal wear. When replacing an existing cylinder, match five key points: bore (32 mm), stroke (390 mm), PT1/8 port thread, basic mounting (no bracket), and the integrated magnet (-S) for sensor compatibility.
Quick checklist
At 0.7 MPa operating pressure, the push force is 563 N and the pull force is 483 N (calculated from the 345 N pull force at 0.5 MPa). The maximum theoretical force at 1.0 MPa is 82 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. You can clamp compatible CMSG, DMSG, or EMSG sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
