The AirTAC SC50 Standard Cylinder SC50X850 is a genuine double-acting standard air cylinder with a Ø50mm bore and 850mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X850 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With an 850 mm stroke and a 20 mm diameter piston rod, this model is well-suited for medium-length transfer and clamping tasks where consistent pneumatic force is required.
This cylinder features a body length A of 150 mm and an adjustable pneumatic cushion of 21 mm at each end to decelerate the piston smoothly. The standard PT1/4 port and M16x1.5 rod thread ensure straightforward integration into existing pneumatic circuits. As a genuine AirTAC SC series unit, it offers a compact tie-rod design that is shorter than a typical ISO 15552 cylinder.

Moves components between conveyor lines or workstations with a controlled 850 mm linear stroke, using the cylinder's 982 N push force at standard line pressure.
Applies consistent clamping pressure for medium-sized workpieces in CNC machining or welding fixtures, leveraging the adjustable cushion for smooth engagement.
Operates diverter gates or sorting paddles in material handling systems, where the long stroke provides a wide sweep angle and the tie-rod design allows easy maintenance.
For applications needing slightly less force, stepping down to a 40 mm bore (SC40 series) provides 628 N of push at 0.5 MPa. If higher force is required, the 63 mm bore (SC63 series) offers 1559 N at the same pressure. Always match replacements across five key points: bore, stroke, port thread (PT), mounting accessory, and the presence of a magnet (-S).
At an 850 mm stroke, the piston rod is extended significantly. To prevent rod bearing wear or bending under side loads, use an external guide or a guided cylinder assembly. The SC50X850 is not designed to hold a load without live air pressure; a pilot-operated check valve or mechanical lock is needed for static load holding.
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. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X850 is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. To hold a load safely without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
