The AirTAC SC50 Standard Cylinder SC50X90S 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 SC50X90S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa) from a 50 mm bore. Its 90 mm stroke is well within the 1200 mm maximum standard stroke for this bore, making it a balanced choice for medium-throw clamping and positioning tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly on the tie-rod barrel for non-contact position sensing. The 20 mm diameter piston rod with M16x1.5 thread provides robust guidance, while the 21 mm adjustable air cushion at each end decelerates the load smoothly.

The built-in magnet allows CMSG/DMSG sensors to confirm clamp position, ideal for automated CNC fixtures and welding jigs where cycle verification is critical.
With 982 N of push force, this cylinder reliably raises part stops or actuates diverter gates on packaging and assembly conveyors, with sensor feedback to the PLC.
Delivers 1767 N at 0.9 MPa for short-stroke pressing, crimping, or forming operations where end-of-stroke confirmation via magnetic sensor prevents incomplete cycles.
Choose the SC50X90S when your application needs around 980 N of force at standard plant pressure. If you require more thrust, the SC63 series provides 1559 N at 0.5 MPa; for lighter, faster cycling, the SC40 series offers 628 N. Always match replacement cylinders on all five critical points: 50 mm bore, 90 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
For strokes of 300 mm or longer, side loads can cause rod bearing wear and bending. At 90 mm, the rod is well-supported, but if your load applies any lateral force, consider adding an external linear guide to protect the cylinder.
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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. Only replace with another AirTAC SC50 cylinder matching the 90 mm stroke, PT1/4 ports, and built-in magnet.
