The AirTAC Airtac SC32 Standard Cylinder SC32X20 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 SC32X20 is a compact double-acting pneumatic cylinder with a 32 mm bore and 20 mm stroke, delivering 402 N of push force at 0.5 MPa (563 N at 0.7 MPa). Its short stroke and 12 mm diameter piston rod make it ideal for light clamping, sorting, and ejecting tasks where space is tight.
With a body length A of just 140 mm and an adjustable air cushion of 21 mm, this tie-rod cylinder decelerates the piston smoothly at end-of-travel without adding bulk. The PT1/8 port and M10x1.25 rod thread keep connections small and industry-standard.

The 20 mm stroke and 402 N push force reliably eject small plastic or metal parts from injection molds and pick-and-place nests.
Actuates small diverter gates on compact conveyor lines, where the short 20 mm stroke provides crisp, repeatable motion without over-travel.
Applies controlled, low-force clamping on delicate assemblies or electronics, using the adjustable cushion to prevent impact damage.
For applications needing more push force, stepping up to the 40 mm bore SC40 delivers 628 N at 0.5 MPa. If space is the primary constraint, the SC32 remains the lightest SC-series option. When replacing an existing cylinder, match all five points: 32 mm bore, 20 mm stroke, PT1/8 port thread, basic mounting (no accessory bracket), and confirm the magnet option (this model has no built-in magnet).
Quick checklist
At 0.7 MPa operating pressure, the SC32X20 produces 563 N of push force and 345 N of pull force (rod side). The theoretical maximum at 1.0 MPa is 82 kgf.
This SC32X20 model does not include the -S magnet option, so CMSG/DMSG/EMSG sensors cannot be used directly on the barrel. For sensor-ready position detection, order the SC32X20-S variant with the built-in magnet.
