The AirTAC Airtac SC32 Standard Cylinder SC32X70 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 SC32X70 is a compact double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 402 N at 0.5 MPa. With a 32 mm bore and 70 mm stroke, it features a 12 mm diameter piston rod and an M10x1.25 rod thread for direct accessory mounting.
Its adjustable air cushion (21 mm length) decelerates the piston smoothly at stroke end, reducing impact noise. The body length A is 140 mm, giving a total extended length of approximately 210 mm. This model uses standard PT1/8 ports and TPU seals for operation in -20 to +70 °C environments.

The 402 N push force at 0.5 MPa is ideal for ejecting lightweight plastic or metal parts from assembly fixtures and pick-and-place stations.
Actuates small diverter gates on packaging lines. The 70 mm stroke provides sufficient travel to redirect products between lanes.
Compact 32 mm bore fits tight spaces in diagnostic equipment, moving sample trays or reagent dispensers with clean, oil-free air.
For higher force, step up to the SC40 bore (628 N push at 0.5 MPa). For lighter, more compact needs, the SC32 remains the entry point in this tie-rod family. Ensure the 70 mm stroke matches your application; non-standard strokes are available on request.
When replacing an existing cylinder, match five points: 32 mm bore, 70 mm stroke, PT1/8 port thread, basic mounting (no bracket), and confirm if a magnet is needed. This SC32X70 is a basic configuration without a built-in magnet, so it is not directly compatible with CMSG/DMSG sensors unless retrofitted with external brackets.
Quick checklist
At 0.7 MPa operating pressure, the SC32X70 cylinder produces a push force of 563 N. The maximum push force at 0.9 MPa is 724 N.
This specific model (SC32X70) does not include the -S suffix, so it has no built-in magnet. To use CMSG or DMSG sensors, order the SC32X70-S variant which includes a magnetized piston ring.
