The AirTAC Airtac SC40 Standard Cylinder SC40X800TC is a genuine double-acting standard air cylinder with a Ø40mm 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 SC40X800TC is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore houses a 16 mm diameter piston rod with an M12x1.25 male thread, and the 800 mm stroke is well within the 1200 mm maximum standard stroke for this bore size.
This model is factory-configured with a centre trunnion (TC) mount, supplied together with the TCM1 bracket (accessory code F-SC40TC). The trunnion allows the cylinder to pivot during operation, making it ideal for swinging or articulating loads. Ports are PT1/4, the adjustable air cushion is 21 mm, and the body length A is 142 mm.

The pivoting action of the TC mount and 800 mm stroke suit medium-length conveyor sorting gates, where the cylinder swings to redirect packages between lanes.
628 N at shop air pressure provides reliable clamping for woodworking or light metal fabrication jigs, with the trunnion allowing the clamp arm to swing clear for part loading.
Operates discharge doors on agricultural hoppers or chutes. The centre trunnion absorbs the arc motion of the door linkage, reducing stress on the rod bearing.
For applications needing more force, stepping up to the SC50 bore provides 982 N push at 0.5 MPa, while the SC32 offers a more compact 402 N alternative. At 800 mm stroke, the 16 mm rod is relatively slender; avoid unguided side loads or couple the cylinder with an external linear guide to prevent rod bending and premature bearing wear.
When replacing an existing unit, match five points: 40 mm bore, 800 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the standard TPU seal. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC 40x800 tie-rod cylinder matching the TC mount and PT1/4 ports.
