The AirTAC SC50 Standard Cylinder SC50X800STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X800STC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration for mid-force automation tasks.
This model includes a built-in magnet for mounting CMSG/DMSG/EMSG sensors directly on the barrel, plus a centre trunnion (TC) mount with the TCM1 bracket for pivoting applications. The 800 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore.

Pivoting gate or diverter arms on packaging lines, using the TC trunnion mount for smooth angular motion and sensor feedback for position confirmation.
Pneumatic clamping fixtures requiring 982 N of force at standard line pressure, with magnetic sensors verifying clamp engagement before a cycle starts.
Long-stroke pushers or lift-assist devices in logistics, where the 800 mm reach moves totes or cartons between conveyor levels.
Choose the SC50X800STC when you need a 50 mm bore cylinder with sensor feedback and a pivoting mount. If your force requirement is lower, the 40 mm bore offers 628 N at 0.5 MPa; for higher force, step up to the 63 mm bore at 1559 N. For this 800 mm stroke, ensure the load is guided if side forces are present—long, unsupported rods are susceptible to bending. To replace this cylinder, match the 50 mm bore, 800 mm stroke, PT port thread, TC centre trunnion mount, and the integrated magnet (-S).
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.
Match the bore (50 mm), stroke (800 mm), PT port thread, centre trunnion (TC) mount with TCM1 bracket, and the built-in magnet (-S). The SC is a tie-rod design, so dimensional interchangeability is limited to another AirTAC SC of the same configuration.
