The AirTAC Airtac SC40 Standard Cylinder SC40X810STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 810mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X810STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 40 mm bore and 16 mm diameter piston rod provide a robust linear drive for medium-duty automation tasks, with an 810 mm stroke suited to longer transfer and positioning operations.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC40TC) for pivoting applications. The adjustable air cushion at each end decelerates the piston smoothly, and the PT1/4 port thread ensures straightforward pneumatic connection.

Pushes or pulls components between conveyor lines over an 810 mm travel, with sensor confirmation via the built-in magnet.
Operates sliding safety doors or guards on machining centres, where the centre trunnion mount allows the cylinder body to pivot.
Directs packages on gravity or powered roller conveyors, using the long stroke to fully extend a diverter gate.
For applications requiring more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. For lighter, more compact needs, the 32 mm bore SC32 offers 402 N. Always match bore, stroke, port thread (PT), mounting accessory (TC with TCM1), and the magnet option (-S) when replacing an existing cylinder.
At an 810 mm stroke, the 16 mm rod is susceptible to bending under side loads. Evaluate the application for off-axis forces and consider an external guide rail or a guided cylinder if the load is not purely axial to prevent rod bearing wear and premature seal failure.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder pushes with 628 N. At 0.7 MPa, force increases to 879 N, and at the maximum 0.9 MPa operating pressure, it reaches 1130 N.
Match five key specs: 40 mm bore, 810 mm stroke, PT1/4 port thread, centre trunnion (TC) mount with the TCM1 bracket (F-SC40TC), and the built-in magnet (-S) for sensors. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to the AirTAC SC series.
