The AirTAC SC50 Standard Cylinder SC50X530SH is a genuine double-acting standard air cylinder with a Ø50mm bore and 530mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X530SH is a double-acting tie-rod cylinder with a 50 mm bore and a non-standard 530 mm stroke, built with a built-in magnet and high-temperature Viton (FKM) seals. Operating on filtered air from 0.15–1.0 MPa, it delivers 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator.
This model's 20 mm diameter piston rod and 21 mm adjustable air cushion help manage end-of-stroke deceleration for the extended 530 mm travel. The Viton seals shift the operating temperature range to 0–150 °C, suiting it for hot or aggressive environments. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for reliable, non-contact position sensing.

The Viton seals enable reliable operation in ambient temperatures up to 150°C, making this cylinder ideal for actuating dampers, valves, or gates in drying ovens, autoclaves, and foundry equipment.
With 1767 N of push force at 0.9 MPa and a 530 mm stroke, it can eject hot-formed parts or scrap from a press or conveyor line where standard seals would degrade, while the magnet provides end-of-stroke confirmation.
The 530 mm reach and FKM seals suit clamping fixtures in paint curing lines. The built-in magnet allows sensor feedback to verify the clamp is fully engaged before the next cycle begins.
For a 50 mm bore, the SC50X530SH provides 982 N at 0.5 MPa. If your load is lighter, stepping down to a 40 mm bore (628 N at 0.5 MPa) can reduce air consumption. For heavier loads, the 63 mm bore offers 1559 N at the same pressure. With a 530 mm stroke, this is a non-standard length that exceeds the 1200 mm maximum standard stroke for the 50 mm bore, so lead times may be longer.
At this stroke length, the unsupported piston rod is susceptible to bending under side loads. Use an external linear guide or a guided cylinder to protect the rod bearings and ensure reliable operation. For a direct replacement, match the 50 mm bore, 530 mm stroke, PT port thread, basic mount, and the -S magnet option exactly.
Quick checklist
At the standard 0.5 MPa operating pressure, the theoretical 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 SC50X530SH is a double-acting cylinder and does not lock or hold position when air pressure is exhausted or the directional valve is centered. The piston will drift or drop. If load holding is required, you must add a pilot-operated check valve or an external mechanical rod brake.
