The AirTAC Airtac SC50 Standard Cylinder SC50X965S is a genuine double-acting standard air cylinder with a Ø50mm bore and 965mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X965S is a double-acting tie-rod cylinder with a 50 mm bore and an extended 965 mm stroke. At 0.5 MPa air pressure it generates 982 N of push force and 825 N of pull force, rising to 1767 N push at the 0.9 MPa maximum operating pressure. The piston rod is 20 mm diameter with an M16x1.5 male thread, and the adjustable air cushion at each end provides 21 mm of controlled deceleration.
This model carries the -S suffix, so a built-in magnet is fitted along the barrel. That lets you clamp CMSG reed switches or DMSG/EMSG solid-state sensors directly onto the tie-rod tube for reliable end-of-stroke or mid-position sensing without external brackets. The standard PT1/4 port threads and TPU seals suit filtered-air service from -20 to +70 °C.

The 965 mm stroke moves parts or pallets across a wide conveyor gap. The built-in magnet allows two sensors to confirm full extend and retract for reliable automation handshakes.
Delivers a steady 982 N push at 0.5 MPa to press a dispensing head along a long linear path. Sensor feedback from the -S magnet confirms position before each dispense cycle.
With 1767 N available at 0.9 MPa, the cylinder can lift or slide a heavy hopper gate. The adjustable cushion softens the stop at both ends, reducing wear on the gate frame.
Choose the SC50 bore when your application needs up to 982 N at 0.5 MPa. If you require more force, the SC63 delivers 1559 N at the same pressure; for a lighter, more compact solution the SC40 provides 628 N. Because the 965 mm stroke is long relative to the 20 mm rod diameter, avoid unsupported side loads — fit an external linear guide or a guided cylinder to protect the rod bearing from bending moments.
When replacing an existing cylinder, match five points: 50 mm bore, 965 mm stroke, PT1/4 port threads, the built-in magnet (-S) for sensor mounting, and the basic (no-bracket) mounting configuration. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile types.
Quick checklist
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa the push force reaches 1767 N. The theoretical force at 1.0 MPa is 200 kgf (1961 N) push.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensors clip directly onto the tie-rod barrel. No external actuator or flag is needed.
