The AirTAC Airtac SC50 Standard Cylinder SC50X950STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 950mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X950STC 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). With a 50 mm bore and a long 950 mm stroke, it uses a 20 mm diameter piston rod and provides an adjustable air cushion of 21 mm at each end to decelerate the load smoothly.
This model is factory-configured with a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC50TC) for pivoting applications. The body length A is 150 mm, giving a total extended length of approximately 1100 mm.

The 950 mm stroke and 982 N push force at 0.5 MPa suit transferring parts between distant conveyor lines or workstations, with the trunnion mount allowing the cylinder body to pivot as it extends.
Delivers consistent clamping force for large welding jigs. The built-in magnet enables easy addition of reed sensors to confirm clamp engagement and release at each cycle end.
The centre trunnion mount is ideal for swinging diverter gates on material handling chutes, where the cylinder must pivot to follow the gate's arc through its full 950 mm stroke.
For applications needing less force, consider stepping down to the 40 mm bore (628 N at 0.5 MPa); for higher thrust, the 63 mm bore offers 1559 N at the same pressure. This 950 mm stroke approaches the 1200 mm maximum standard stroke for the 50 mm bore, so ensure the rod is adequately supported against side loads—an external linear guide or a guided cylinder configuration is strongly recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five key points: 50 mm bore, 950 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is dimensionally shorter than an ISO 15552 profile cylinder and is not a drop-in interchange for that standard.
Quick checklist
At the standard 0.5 MPa operating pressure, 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. The theoretical maximum force at 1.0 MPa is 200 kgf.
The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. For a direct replacement, match the SC series specifically, verifying the 50 mm bore, 950 mm stroke, PT ports, and TC centre trunnion mount.
