The AirTAC SC50 Standard Cylinder SC50X920 is a genuine double-acting standard air cylinder with a Ø50mm bore and 920mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X920 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 920 mm stroke. At 0.5 MPa it delivers 982 N pushing force and 825 N pulling force, while the maximum operating thrust at 0.9 MPa reaches 1767 N, driven by a 20 mm diameter piston rod.
This model features a 150 mm body length (dimension A) and PT1/4 ports with M16x1.5 rod thread. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, protecting end caps during high-cycle operation. The 920 mm stroke is within the standard range for bore 50, which extends up to 1200 mm.

The 920 mm stroke moves components between distant conveyor stations in packaging lines, providing consistent push force without complex linkages.
Delivers 1767 N of clamping force at 0.9 MPa for holding workpieces in CNC fixtures, with adjustable cushioning to reduce impact on precision parts.
Operates diverter gates or stoppers in gravity-fed chutes, using the long stroke to fully retract the blade from the product flow path.
Choose the SC50 bore when your application needs roughly 980 N of push force at standard plant air. 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 bore delivers 628 N. Always match replacement cylinders on five points: 50 mm bore, 920 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the absence of a built-in magnet.
With a 920 mm stroke, the 20 mm rod is susceptible to bending under side loads. For this stroke length, consider adding an external linear guide or switching to a guided-cylinder configuration if the load is not perfectly axial. The SC cylinder relies on the rod bearing alone and is not designed to absorb lateral forces.
Quick checklist
At 0.7 MPa operating pressure the SC50X920 produces 1374 N of force when extending (push) and 1155 N when retracting (pull), based on the 50 mm bore and 20 mm rod diameter. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and overall length differ. It is a direct dimensional match only for another AirTAC SC tie-rod cylinder with the same bore, stroke, port thread, and mounting configuration.
