The AirTAC SC50 Standard Cylinder SC50X540TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 540mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X540TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 50 mm bore and 540 mm stroke suit medium-force linear tasks where the cylinder needs to pivot during operation, handled by the factory-fitted centre trunnion mount.
This tie-rod cylinder uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The 540 mm stroke is within the 1200 mm maximum standard stroke for bore 50, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-travel.

The centre trunnion mount allows the cylinder body to swing as it actuates a diverter gate or flap on a conveyor line, handling repetitive medium-force cycling at 540 mm stroke.
Delivers 1767 N of clamping force at 0.9 MPa for holding workpieces in CNC or welding fixtures, with the trunnion mount simplifying alignment in tight machine envelopes.
Operates chute deflectors or hopper doors on farming equipment, where the pivoting TC mount absorbs misalignment and the TPU seals handle standard outdoor temperature ranges.
For applications needing slightly more force, stepping up to a 63 mm bore (1559 N at 0.5 MPa) is a direct option. If space is tight and less force is acceptable, the 40 mm bore (628 N at 0.5 MPa) offers a smaller body length A of 142 mm. At 540 mm stroke, the 20 mm rod is relatively slender; avoid unguided side loads that can bend the rod or wear the bearing. Use external linear guides or a guided cylinder for off-axis loads.
To replace an existing SC50X540TC, match five points: 50 mm bore, 540 mm stroke, PT1/4 port thread, centre trunnion (TC) mount with the TCM1 bracket (F-SC50TC), and the absence of a magnet. The SC is a tie-rod cylinder 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.
No. The SC50X540TC is a double-acting cylinder and does not lock or hold position when air pressure is exhausted or the valve is centred. The piston will drift or drop under load. If load holding is required, add a pilot-operated check valve or an external mechanical rod brake.
