The AirTAC SC50 Standard Cylinder SC50X90STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 90mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X90STC is a double-acting pneumatic cylinder with a 50 mm bore and 90 mm stroke, delivering a push force of 982 N at 0.5 MPa (1767 N at the maximum operating pressure of 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration, making it suitable for medium-force clamping and transfer tasks.
This configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, and a centre trunnion mount (TC) with the TCM1 bracket (F-SC50TC) for pivoting applications. The standard TPU seals and PT1/4 port threads suit normal operating temperatures from -20 to +70 °C.

The 90 mm stroke and centre trunnion mount allow the cylinder to pivot, directing packages or components between two conveyor lanes with a 982 N push force.
With a built-in magnet for end-of-stroke sensing, this cylinder confirms clamp closure in automated welding fixtures, handling 1767 N of clamping force at 0.9 MPa.
The adjustable cushion decelerates the 20 mm rod smoothly at the end of the 90 mm stroke, ideal for pushing components into a test station without impact damage.
For a 90 mm stroke, the SC50 bore provides a balanced force-to-size ratio. If you need higher force, stepping up to the SC63 bore offers 1559 N push at 0.5 MPa; for a lighter, more compact solution, the SC40 bore delivers 628 N. This cylinder is a genuine AirTAC tie-rod unit, not an ISO 15552 profile, so replacements must match bore, stroke, PT port thread, the TC centre trunnion mounting, and the -S magnet option.
At this stroke length, the 20 mm rod is well-supported within the cylinder body, but always avoid direct side loads. For applications with significant lateral forces, use an external linear guide to protect the rod bearing and seals from premature wear.
Quick checklist
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
Yes. The -S suffix in the model code indicates a built-in magnet along the barrel. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
