The AirTAC Airtac SC40 Standard Cylinder SC40X215H is a genuine double-acting standard air cylinder with a Ø40mm bore and 215mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X215H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 215 mm stroke. Its Viton (FKM) seals shift the operating temperature window to 0–150 °C, making this unit suitable for hot zones, autoclaves, and aggressive environments where standard TPU seals would degrade. At 0.5 MPa it generates 628 N extending and 528 N retracting, placing it in a practical mid-force class for thermal-process machinery.
This model uses a 16 mm diameter piston rod with an M12x1.25 male thread and PT1/4 ports. The adjustable air cushion at each end (21 mm length) decelerates the load smoothly, while the tie-rod construction keeps the body length compact at 142 mm (A dimension). The 215 mm stroke is within the standard range for the 40 mm bore, so no special order lead-time applies.

Viton seals allow continuous operation up to 150 °C, making this cylinder ideal for clamping, ejecting, or diverting parts inside ovens, thermoforming stations, and autoclave lids.
FKM material resists many aggressive chemicals and cleaning agents better than standard TPU. Use the SC40X215H on sterilizer doors, dosing valves, or mixing-batch gates where chemical attack is a concern.
With 628 N of push force at 0.5 MPa and a 215 mm stroke, it handles medium-weight package diverters, lane guides, and reject-station pushers on heated packaging lines.
Choose the SC40X215H when your application demands heat resistance up to 150 °C and a force around 628 N at standard shop air. If you need more push without raising pressure, stepping up to the SC50 bore delivers 982 N at the same 0.5 MPa. For lighter, cooler-duty tasks, the SC32 bore provides 402 N. The 215 mm stroke is moderate, but if the rod sees any side load, pair the cylinder with an external guide or a guided cylinder to protect the rod bearing from bending stress.
For drop-in replacement, match five points: 40 mm bore, 215 mm stroke, PT1/4 port thread, basic (no accessory) mounting, and the Viton seal suffix (H). This cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders; it replaces another AirTAC SC40 tie-rod unit of the same configuration.
Quick checklist
At 0.5 MPa (5 bar) the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the extending force rises to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC40X215H is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a position or load without live pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
