The AirTAC SC50 Standard Cylinder SC50X90LB is a genuine double-acting standard air cylinder with a Ø50mm bore and 90mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X90LB is a 50 mm bore double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 90 mm stroke suits medium-reach clamping and pressing tasks, with a 20 mm diameter piston rod providing good column strength.
This model includes LB axial foot mounts (part F-SC50LB) for secure surface mounting on machine frames. The tie-rod construction uses TPU seals for standard -20 to +70 °C operation, with PT1/4 ports and an adjustable air cushion to decelerate the 20 mm rod smoothly at stroke end.

The 982 N push force at 0.5 MPa reliably actuates stop gates and diverters on packaging lines, holding product totes for filling or scanning.
Ideal for pneumatic clamps on CNC jigs. The 20 mm rod resists bending under direct axial loads, securing workpieces during light machining.
Foot-mounted on a lift table, the 90 mm stroke provides a controlled push to tilt bins or hoppers for ergonomic parts presentation.
For higher force, step up to the 63 mm bore SC63 series, which provides 1559 N push at 0.5 MPa. If a shorter, more compact cylinder suits the space, the 40 mm bore SC40 offers 628 N. When replacing, match bore (50 mm), stroke (90 mm), PT1/4 port thread, LB foot mount, and the absence of a magnet sensor option to ensure direct fitment. The 90 mm stroke is well within the 1200 mm maximum standard stroke for this bore, keeping lead times short.
Quick checklist
At 0.5 MPa, push force is 982 N and 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.
Yes, the LB foot mount (accessory F-SC50LB) is bolted to the cylinder body and can be removed or swapped for other AirTAC SC50 mounting types like FA flange or CA clevis if your machine layout changes.
