The AirTAC Airtac SC32 Standard Cylinder SC32X420S is a genuine double-acting standard air cylinder with a Ø32mm bore and 420mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X420S is a double-acting pneumatic cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). Its 420 mm stroke is well within the 1000 mm maximum standard stroke for the 32 mm bore, making this a standard-configuration actuator with a 12 mm diameter piston rod and M10x1.25 rod thread for end tooling.
This model includes the -S suffix, equipping the cylinder with a built-in magnet. This allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for reliable, non-contact end-of-stroke or mid-stroke position sensing without external brackets. The body length A is 140 mm, giving a total extended length of approximately 560 mm.

The 420 mm stroke with magnetic piston sensing provides precise confirmation of part ejection in small assembly fixtures, ensuring the rod has fully retracted before the next cycle.
Operates a small gate or diverter flap on a conveyor line handling lightweight packages. The 402 N push force at 0.5 MPa is well-matched to compact sorting mechanisms.
Suited for linear transfer in diagnostic or lab automation equipment. The built-in magnet enables sensor feedback for precise position verification in clean, light-load environments.
Choose the SC32 bore for light automation tasks where the 402 N push force at 0.5 MPa is sufficient. If your application requires more force, step up to the SC40 bore which provides 628 N at the same pressure. For strokes of 300 mm or longer, like this 420 mm unit, avoid applying side loads directly to the rod; the 12 mm rod can bend under lateral force. Use an external linear guide or a guided cylinder variant to absorb the moment load and protect the rod bearing.
When replacing an existing cylinder, match five points exactly: 32 mm bore, 420 mm stroke, PT1/8 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting. This is a tie-rod cylinder with a shorter body than an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC32 of the same configuration.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force on retraction is 345 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows you to clamp compatible CMSG, DMSG, or EMSG sensors directly onto the cylinder's tie-rod barrel for position sensing without any additional mounting hardware.
