The AirTAC SC50 Standard Cylinder SC50X500CB is a genuine double-acting standard air cylinder with a Ø50mm bore and 500mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X500CB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), built around a 20 mm diameter piston rod for robust linear actuation. With a 500 mm stroke and a rear double clevis (CB) mount, it is designed to pivot freely at the cap end, absorbing misalignment in articulated linkages.
This model features a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, making the total extended length approximately 650 mm. It uses PT1/4 ports and an M16x1.5 rod thread, with TPU seals for a standard operating range of -20 to +70 °C.

The rear clevis mount allows the cylinder to pivot as it actuates a chute or gate on harvesting equipment, handling dusty conditions with the standard TPU seals.
Provides the mid-range force needed to swing a diverter paddle across a conveyor line, with the 500 mm stroke offering ample travel for wide belt systems.
Delivers consistent clamping force for metal fabrication jigs, where the CB mount simplifies installation on a pivoting bracket and the air cushion protects the fixture from hammering.
Choose the SC50 bore when your application needs around 982 N of force at standard plant pressure; if you require roughly 1559 N, step up to the SC63 bore. For lighter tasks around 628 N, the SC40 bore may be a more compact choice. The 500 mm stroke is within the standard range for this bore (max 1200 mm), but at this length, avoid unsupported side loads that can bend the 20 mm rod—consider an external guide rail if the load is not purely axial.
To replace an existing cylinder, match five points exactly: 50 mm bore, 500 mm stroke, PT port thread, rear double clevis CB mounting (part F-SC50CB), and confirm no magnet is needed. This tie-rod SC cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
Quick checklist
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. 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 cylinder of the same bore and stroke, so mounting dimensions and body length do not match. It is a direct replacement only for another AirTAC SC50 cylinder with the same stroke, PT ports, and CB rear double clevis mount.
