The AirTAC SC50 Standard Cylinder SC50X285 is a genuine double-acting standard air cylinder with a Ø50mm bore and 285mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X285 is a double-acting tie-rod cylinder that generates 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a capable mid-range actuator for pressing, clamping, and material-transfer tasks. Its 285 mm stroke is within the standard range for the 50 mm bore, which supports strokes up to 1200 mm, and the 20 mm diameter piston rod provides solid rigidity for linear motion.
This model features a 150 mm body length (dimension A) and a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The PT1/4 port and M16x1.5 rod thread are standard, and the cylinder operates on filtered air from 0.15 to 1.0 MPa across a -20 to +70 °C temperature range with its default TPU seals.

The 285 mm stroke and 982 N push force at 0.5 MPa suit linear transfer units that shuttle components between conveyor belts or workstations in automated assembly lines.
Delivers controlled force for pressing bearings, bushings, or pins into housings where a short, guided stroke and adjustable cushion protect the workpiece from impact damage.
Used in welding or machining fixtures to hold parts securely. The double-acting design provides positive clamp and release, with the 20 mm rod offering good resistance to bending under clamping loads.
Choose the SC50X285 when your application needs roughly 1000 N of force at typical shop air pressure. If you require more force, stepping up to the 63 mm bore (SC63) provides 1559 N push at 0.5 MPa—a 58% increase—while the 40 mm bore (SC40) offers 628 N if a smaller, lighter cylinder is preferred. For strokes of 300 mm or longer, be mindful of side loads: an unsupported 20 mm rod at full extension can experience bending stress. Add an external guide rail or switch to a guided cylinder if the load is not perfectly axial.
To replace an existing SC50 cylinder, match five points exactly: 50 mm bore, 285 mm stroke, PT1/4 port thread, the required mounting accessory (this basic model has none), and the presence or absence of a magnet. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf (approx. 1961 N).
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder, so mounting dimensions and accessory interfaces differ. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching stroke, port thread, and mounting configuration.
