The AirTAC SC50 Standard Cylinder SC50X75FB is a genuine double-acting standard air cylinder with a Ø50mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X75FB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa maximum operating pressure). Its 75 mm stroke suits short linear transfer and clamping tasks where a compact, rigidly mounted actuator is needed.
This model features a rear rectangular flange (FB) for secure end-face mounting, with a 20 mm piston rod and M16x1.5 male rod thread. The 50 mm bore body has a length of 150 mm, adjustable air cushioning at both ends, and PT1/4 ports. It operates on filtered air from -20 to +70 °C with standard TPU seals.

The rear flange mount and 982 N push force make this cylinder ideal for actuating grippers or clamps on robotic end-of-arm tooling where a rigid, space-efficient mounting is required.
Use the 75 mm stroke to deploy a positive part stop on a conveyor line. The adjustable cushion decelerates the rod gently, reducing impact noise and part bounce at the end of travel.
Mount the cylinder via the rear flange to a welding or assembly fixture. The 1767 N maximum force at 0.9 MPa provides ample clamping pressure for holding workpieces during processing.
The SC50 bore sits between the lighter SC40 (628 N at 0.5 MPa) and the more powerful SC63 (1559 N at 0.5 MPa). Choose the SC50X75FB when you need the rear flange mounting style and a force around 1 kN, but step up to the SC63 if your load approaches 1400 N. For strokes over 200 mm on this 20 mm rod, evaluate side-load forces and consider an external linear guide.
To replace an existing cylinder, match five points: 50 mm bore, 75 mm stroke, PT1/4 port thread, the FB rear flange mounting (accessory F-SC50FB), and the absence of a magnet. This tie-rod SC cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 reaches 1767 N. These values are for a double-acting cylinder in extension and retraction.
The FB suffix designates a rear rectangular flange for fixed, face-mounting. For pivoting applications, you would need a rear clevis mount (CA or CB) or a centre trunnion (TC). This specific model is not designed to pivot on its mount.
