The AirTAC Airtac SC50 Standard Cylinder SC50X930SH is a genuine double-acting standard air cylinder with a Ø50mm bore and 930mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X930SH is a double-acting tie-rod cylinder with a 50 mm bore and an extended 930 mm stroke, equipped with high-temperature Viton seals and a built-in magnet for barrel-mounted sensors. Its 20 mm diameter piston rod generates 982 N of push force at 0.5 MPa, rising to 1767 N at the maximum operating pressure of 0.9 MPa.
This model's -S magnet option allows direct clamping of CMSG/DMSG/EMSG reed or solid-state sensors for reliable end-of-stroke detection without external brackets. The H suffix specifies Viton (FKM) seals, shifting the operating temperature range to 0 to +150 °C, making it suitable for hot environments where standard TPU seals would degrade. The 21 mm adjustable air cushion at each end decelerates the piston smoothly, protecting the end caps during high-cycle operation.

Viton seals withstand 0 to +150 °C, making this cylinder ideal for heated platen actuation in laminating presses, rubber moulding, and composite curing where standard seals would fail.
The 930 mm stroke provides extended reach for pushers or diverters on conveyor lines in bakeries, autoclaves, or drying ovens. The built-in magnet enables sensor feedback in tight thermal enclosures.
With 1767 N of clamping force at 0.9 MPa, this cylinder secures parts in robotic welding cells. The Viton seals resist weld spatter heat, and the magnetic piston allows position confirmation via barrel-mounted sensors.
Select the SC50 bore when your application needs roughly 1000 N of force at standard plant air pressure. If you require more force, stepping up to the SC63 bore provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the SC40 delivers 628 N. At a 930 mm stroke, the rod is fully extended well beyond the 150 mm body length, so evaluate side-loading carefully—an external guide rail or a guided cylinder is recommended to prevent rod bearing wear and bending under off-axis loads.
For a direct replacement, match five key points: 50 mm bore, 930 mm stroke, PT port thread, the built-in magnet for sensor mounting, and the Viton seal material for high-temperature compatibility. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the push force is 982 N; at 0.7 MPa, it is 1374 N; and at the maximum operating pressure of 0.9 MPa, it reaches 1767 N. The pull force on the retract stroke is slightly lower due to the rod area: 825 N at 0.5 MPa.
No. The SC50X930SH is a double-acting cylinder and does not lock or hold position when air pressure is exhausted or the directional valve is centred. If load holding is required, you must add a pilot-operated check valve or an external mechanical rod brake.
