The AirTAC Airtac SC50 Standard Cylinder SC50X660CA is a genuine double-acting standard air cylinder with a Ø50mm bore and 660mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X660CA is a double-acting tie-rod cylinder delivering 982 N push force at 0.5 MPa (1374 N at 0.7 MPa), built around a 20 mm diameter piston rod and PT1/4 ports. Its 660 mm stroke is paired with a rear single clevis (CA) mount, allowing the cylinder body to pivot during actuation—ideal for articulated linkages and dump mechanisms.
With a body length A of 150 mm, the extended length reaches approximately 810 mm. The adjustable air cushion (21 mm) decelerates the piston smoothly at each end, protecting end caps from impact. This model uses standard TPU seals for a -20 to +70 °C operating range and PT threads; the CA mount ships as accessory F-SC50CA.

The rear clevis pivot and 660 mm stroke suit hopper discharge gates on agricultural silos or feed mixers, where the cylinder must swing as the gate opens and closes.
Delivers consistent 982 N force to tension long conveyor belts. The clevis mount lets the cylinder pivot as belt stretch is taken up, maintaining alignment.
Used in automotive jigs where a pivoting cylinder clamps large weldments. The 660 mm stroke reaches across wide fixtures, and the adjustable cushion prevents impact chatter.
For a 50 mm bore at 0.5 MPa, expect 982 N push / 825 N pull. If your load exceeds ~800 N, step up to a 63 mm bore (1559 N at 0.5 MPa) to gain margin. At 660 mm stroke, the 20 mm rod is long enough that side loads must be managed—fit an external guide rail or linear bearing to prevent rod bending and premature seal wear.
When replacing this cylinder, match five points: 50 mm bore, 660 mm stroke, PT1/4 port thread, rear single clevis (CA) mounting, and the absence of a magnet. The SC is a tie-rod design, shorter than ISO 15552, so dimensional interchangeability is limited to another AirTAC SC of the same configuration.
Quick checklist
At 0.5 MPa air pressure, this 50 mm bore cylinder produces 982 N pushing force and 825 N pulling force (rod side). At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
The CA suffix means this cylinder is supplied with a rear single clevis bracket (F-SC50CA) designed for pivoting applications. If you need a fixed, rigid mount, choose the basic (no mounting) version or an LB foot mount instead. The clevis is not intended to be removed for fixed bolting.
