The AirTAC SC50 Standard Cylinder SC50X850H 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 SC50X850H is a double-acting pneumatic cylinder with a 50 mm bore and an 850 mm stroke, fitted with high-temperature Viton (FKM) seals for reliable operation in environments from 0 to +150 °C. This model delivers a theoretical push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, providing ample thrust for medium-duty actuation tasks.
Built on the compact AirTAC SC tie-rod platform, the cylinder body length is 150 mm, resulting in an extended length of approximately 1000 mm. The 20 mm diameter piston rod features an M16x1.5 male thread, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends of stroke, protecting end caps from impact wear. PT1/4 ports are standard.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
With Viton seals rated to +150 °C, this cylinder is ideal for actuating dampers, gates, or clamps near ovens, autoclaves, and foundry equipment where standard seals would fail.
The 850 mm stroke moves heavy trays or components between conveyor lanes in packaging and assembly lines, with adjustable cushioning to protect the load at end-of-stroke.
Suitable for clamping and positioning in hot-melt adhesive stations or plastic welding jigs, resisting seal degradation from radiant heat and aggressive airborne contaminants.
For a 50 mm bore at 0.5 MPa, the cylinder provides 982 N of push force. If your application requires higher force, stepping up to the 63 mm bore (1559 N at 0.5 MPa) is a direct option; for lighter, faster cycling, the 40 mm bore (628 N) reduces air consumption. This cylinder uses the standard PT thread and does not include a magnet or mounting accessories, which must be ordered separately if needed.
At 850 mm stroke, the unsupported rod is subject to bending under side loads. For this stroke length, an external linear guide or rod support is strongly recommended to prevent rod bearing wear and ensure consistent alignment. When replacing, match five key points: 50 mm bore, 850 mm stroke, PT1/4 port thread, basic mount (no brackets), and absence of a magnet.
Quick checklist
At 0.7 MPa operating pressure, the 50 mm bore SC cylinder generates 1374 N of push force. The maximum push force at 0.9 MPa is 1767 N. Always operate within the 0.15–1.0 MPa range.
No. The SC50X850H is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. To hold a position without live pressure, you must add an external rod brake, mechanical lock, or a pilot-operated check valve.
