The AirTAC SC50 Standard Cylinder SC50X65STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 65mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X65STC is a double-acting AirTAC SC tie-rod cylinder with a 50 mm bore and 65 mm stroke, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the 0.9 MPa maximum operating pressure. Its 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration for moderate-load positioning tasks.
This model is factory-equipped with a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the barrel for non-contact position sensing. The TC centre trunnion mount (supplied with the TCM1 bracket, accessory code F-SC50TC) allows the cylinder to pivot, making it ideal for swinging or articulating linkages. Standard PT ports and TPU seals suit general industrial air service from -20 to +70 °C.

The 65 mm stroke and centre trunnion pivot let this cylinder swing a diverter gate on a packaging or sortation conveyor, with magnetic sensors confirming open/closed position for the PLC.
Delivers 982 N at 0.5 MPa to hold workpieces in machining or welding fixtures. The built-in magnet enables compact sensor mounting for clamp-confirmation signals without external brackets.
The trunnion-mounted SC50X65STC pivots freely to operate quarter-turn valves or dampers via a linkage, with adjustable cushioning softening end-of-stroke impact at the 65 mm travel limit.
Choose the SC50 when your application needs roughly 1000 N of push force at standard shop air; stepping down to a 40 mm bore drops force to 628 N at 0.5 MPa, while moving up to a 63 mm bore raises it to 1559 N. The 65 mm stroke is a standard length within the 50 mm bore’s 1200 mm maximum, so lead times are short.
For replacement, match five points: 50 mm bore, 65 mm stroke, PT port thread, TC centre trunnion mount with TCM1 bracket, and the -S magnet for sensor compatibility. The trunnion pivot handles angular motion, but if the rod sees side load, add an external linear guide—the 20 mm rod is not designed to support bending moments on its own.
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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, provided the original was an AirTAC SC tie-rod cylinder with PT ports and a TC centre trunnion mount. The -S magnet adds sensor capability but does not change the envelope or porting—just ensure your control system can use CMSG/DMSG/EMSG sensors if you plan to wire them.
