The AirTAC SC50 Standard Cylinder SC50X85S is a genuine double-acting standard air cylinder with a Ø50mm bore and 85mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X85S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa. With an 85 mm stroke and a 20 mm diameter piston rod, it suits medium-force clamping and pressing tasks where the working length is under 100 mm.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for reliable end-of-stroke detection. The body length A is 150 mm, and the total extended length is approximately 235 mm.

The integrated magnet enables CMSG/DMSG sensors to confirm clamp closure on assembly fixtures, preventing cycle-start faults.
Actuates diverter gates on packaging lines with sensor feedback confirming gate position for the PLC.
Provides 982 N insertion force with magnetic piston sensing to verify full stroke completion in bearing press tooling.
For higher force, step up to the SC63 bore which provides 1559 N push at 0.5 MPa. If a shorter stroke with the same sensor capability is needed, the SC50X75S is a direct alternative. When replacing, match the 50 mm bore, 85 mm stroke, PT1/4 port thread, TPU seals, and the -S magnet option exactly. The built-in magnet eliminates the need for external switch mounting brackets.
Quick checklist
At 0.5 MPa it pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
Yes, the -S suffix denotes a built-in magnet specifically for AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that clamp directly onto the tie-rod barrel.
