The AirTAC SC50 Standard Cylinder SC50X800SN is a genuine double-acting standard air cylinder with a Ø50mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X800SN is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), built around a 20 mm diameter piston rod and PT1/4 ports. With an 800 mm stroke and a body length A of 150 mm, the total extended length reaches 950 mm, making it a capable mid-bore actuator for longer linear moves.
This variant is fitted with NBR (nitrile) seals, offering reliable performance within the standard -20 to +70 °C temperature range. The adjustable air cushion (21 mm) decelerates the piston smoothly at end-of-stroke, protecting the end caps during high-cycle operation.

Moves components 800 mm across a conveyor or assembly station, using the 50 mm bore's force to push or lift reliably at standard line pressure.
Applies 982 N of holding force in welding or machining fixtures, with NBR seals providing a cost-effective solution for ambient-temperature workshops.
Extends to push boxes or product layers into position, where the long 800 mm stroke reaches across a pallet or packing station.
Choose the SC50 when your application needs force in the 1000 N class at typical plant pressure. If the load is lighter and speed is critical, stepping down to a 40 mm bore (628 N push at 0.5 MPa) reduces air consumption. For heavier tooling, the 63 mm bore provides 1559 N at the same pressure.
At 800 mm stroke, the 20 mm rod is susceptible to bending under side loads. Use an external linear guide or a guided cylinder to protect the rod bearing and piston seals. For replacement, match bore (50 mm), stroke (800 mm), PT port thread, NBR seal material, and basic mounting—this model does not include a magnet or mounting bracket.
Quick checklist
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa the push force rises to 1374 N. The maximum operating pressure is 1.0 MPa, producing a theoretical push of 1767 N.
At this stroke length, side loads can bend the 20 mm rod and wear the bearing. Mount the cylinder so the load is purely axial, or add an external guide rail. For applications with unavoidable side forces, consider a guided cylinder or a larger bore with a thicker rod.
