The AirTAC SC50 Standard Cylinder SC50X90 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 AirTAC SC50X90 is a 50 mm bore double-acting tie-rod cylinder with a 90 mm stroke, delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa maximum operating pressure). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
With a compact body length A of 150 mm and PT1/4 ports, this cylinder suits space-constrained automation where genuine AirTAC build quality and consistent cycle life are required. The standard TPU seals cover a -20 to +70 °C operating range.

The 982 N push force at 0.5 MPa easily stops or diverts medium-weight totes and cartons on powered roller conveyors.
Delivers consistent clamping pressure for CNC jigs and welding fixtures, with the 21 mm cushion absorbing impact at end of stroke.
The 90 mm stroke is ideal for right-angle transfers in case packers, pushing products squarely into cartons.
The SC50X90 sits between the smaller 40 mm bore (628 N at 0.5 MPa) and the larger 63 mm bore (1559 N at 0.5 MPa). Step up to the SC63 if your load exceeds 800 N in dynamic conditions. For a direct replacement, match five points: 50 mm bore, 90 mm stroke, PT port thread, basic mounting (no bracket), and no magnet.
At 90 mm stroke the rod is well supported, but if you later extend stroke beyond 300 mm on this rod size, add an external guide to protect the rod bearing from side loads.
Quick checklist
At 0.7 MPa the SC50X90 produces 1374 N of push force and 825 N of pull force, based on the 50 mm bore and 20 mm rod diameter.
This basic model ships without a bracket. You can order the centre trunnion kit separately (F-SC50TC, which includes the TCM1 bracket) and fit it to the tie rods for pivoting motion.
