The AirTAC SC50 Standard Cylinder SC50X85 is a genuine double-acting standard air cylinder with a Ø50mm bore and 85mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X85 is a double-acting pneumatic cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With an 85 mm stroke and a 20 mm diameter piston rod, this model is well-suited for medium-duty clamping, pressing, and ejector tasks where a compact tie-rod body is preferred.
This genuine AirTAC SC cylinder features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, giving a total extended length of approximately 235 mm. Standard PT1/4 ports and an M16x1.5 rod thread simplify pneumatic connections and tooling attachment.

The 85 mm stroke and 982 N push force at 0.5 MPa reliably actuates diverter gates on packaging and assembly conveyors, sorting products by size or destination.
Ideal for pneumatic clamping in woodworking or light metalworking jigs. The adjustable cushion protects the fixture from hammering, maintaining precision over high-cycle runs.
Provides a clean, repeatable ejection stroke for plastic injection molding or stamping presses, where the 20 mm rod resists buckling under axial loads.
For applications needing more force, stepping up to the 63 mm bore provides 1559 N push at 0.5 MPa. If space or air consumption is a concern, the 40 mm bore offers 628 N at the same pressure. When replacing an existing cylinder, match five points: 50 mm bore, 85 mm stroke, PT1/4 port thread, the specific mounting accessory (this model is basic, without brackets), and the absence of a magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. For a direct replacement, match another AirTAC SC tie-rod cylinder with the same 50 mm bore, 85 mm stroke, and PT port thread.
