The AirTAC Airtac SC40 Standard Cylinder SC40X650TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 650mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X650TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke applications.
This model includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC40TC), allowing the cylinder to pivot during operation. With a 650 mm stroke and a compact body length A of 142 mm, it suits installations requiring angular movement in confined spaces.

Pivoting gate or diverter arms on packaging lines, where the trunnion mount allows the cylinder body to swing as the rod extends and retracts.
Pneumatic clamping in woodworking or light metalworking jigs, using the 628 N force to hold workpieces securely during machining or assembly.
Actuating chutes or flow-control flaps on seeders and spreaders, where the pivoting TC mount accommodates the arc of the mechanism.
For higher force, step up to the 50 mm bore SC50 series (982 N at 0.5 MPa). For lighter loads, the 32 mm bore offers 402 N. At 650 mm stroke, the rod is extended significantly; ensure side loads are managed with an external guide to prevent rod bearing wear and bending.
When replacing, match five points: 40 mm bore, 650 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and confirm if a magnet (-S) is needed for sensors.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N.
The TC suffix means it is supplied with a centre trunnion bracket for pivoting. For rigid surface mounting, consider an LB foot mount (SC40X650LB) or FA/FB flange mounts, and order the corresponding accessory kit.
