The AirTAC SC50 Standard Cylinder SC50X55TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 55mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X55TC is a double-acting pneumatic cylinder delivering a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa). Its 55 mm stroke is a standard length for the 50 mm bore, making it a practical choice for short linear movements in compact machinery.
This model features a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The integrated centre trunnion mount (TC) ships with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot during operation. The adjustable air cushion, with a 21 mm cushion length, decelerates the piston smoothly at end-of-stroke.

The pivoting action of the TC mount and 982 N push force at 0.5 MPa reliably actuates diverter gates on packaging and sorting conveyors.
Delivers controlled clamping force for workholding in machining centres, with the trunnion mount allowing the cylinder to swing clear for part loading.
Operates chute deflectors or hopper doors on farming equipment, with TPU seals rated for standard temperatures from -20 to +70 °C.
For higher force requirements, stepping up to a 63 mm bore provides 1559 N at 0.5 MPa, while a 40 mm bore offers 628 N for lighter tasks. Centre trunnion mounting is ideal for applications where the cylinder body must swing through an arc; ensure the pivot axis is correctly aligned to avoid binding.
When replacing an existing cylinder, match five key points: 50 mm bore, 55 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting, and the absence of a magnet. This is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile, so it is not a direct replacement for those types.
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. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The TC suffix indicates a factory-fitted centre trunnion mount, supplied with the TCM1 bracket (order code F-SC50TC). This allows the cylinder body to pivot, accommodating angular movement of the connected load.
