The AirTAC SC50 Standard Cylinder SC50X65H is a genuine double-acting standard air cylinder with a Ø50mm bore and 65mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X65H is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, rising to 1767 N at the 0.9 MPa maximum operating pressure. Its 65 mm stroke suits short clamping, ejecting, and sorting tasks in hot environments.
This model is built with Viton (FKM) seals, shifting the operating temperature range to 0–150 °C for reliable performance in foundries, autoclaves, and engine test cells. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/4 port supplies standard flow.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Viton seals allow the SC50X65H to operate continuously at 150 °C, making it ideal for actuating gates or diverters on drying ovens and heat-treatment lines where standard seals would degrade.
Delivers 1767 N of clamping force at 0.9 MPa for welding jigs and soldering fixtures exposed to radiant heat, maintaining seal integrity across repeated hot cycles.
With a 65 mm stroke and 0–150 °C rating, this cylinder reliably locks and unlocks autoclave doors, resisting steam and aggressive cleaning agents without seal swelling.
For applications needing more force at the same pressure, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If a shorter, lighter cylinder is acceptable, the 40 mm bore delivers 628 N. The 65 mm stroke is a standard offering within the 50 mm bore’s 1200 mm maximum.
When replacing this cylinder, match five points: 50 mm bore, 65 mm stroke, PT1/4 port thread, the Viton seal designation (H), and the basic (no bracket) mounting. The SC50X65H is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa operating pressure, the 50 mm bore SC cylinder generates 1374 N of push force. The pull force on the retract stroke is 825 N at 0.5 MPa, reduced by the 20 mm rod area.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder of the same bore and stroke. It will only drop in as a replacement for another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, and mounting.
