The AirTAC Airtac SC40 Standard Cylinder SC40X750TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 750mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X750TC is a double-acting pneumatic 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, and the 750 mm stroke suits medium-reach material transfer and actuation tasks.
This model is configured with a TC centre trunnion mount (supplied with TCM1 bracket, order code F-SC40TC), allowing the cylinder to pivot during operation. The standard PT1/4 port and adjustable air cushion at both ends ensure smooth deceleration, with a body length A of 142 mm plus the stroke.

The TC centre trunnion mount lets this cylinder swing to actuate a diverter gate on a packaging line, handling 628 N of push force at standard plant pressure.
Delivers 1130 N of clamping force at 0.9 MPa for a robotic welding cell, with the trunnion mount absorbing the arc of the clamping arm.
Operates a pivoting chute on a seed hopper, using the 750 mm stroke to fully open and close the discharge path under dusty conditions.
Choose the SC40 bore when your application needs between 628 N and 1130 N of pneumatic force. If you require more thrust, step up to the SC50 (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 provides 402 N. The 750 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
For a stroke of this length, avoid exposing the rod to direct side loads. If the load path is not perfectly axial, use an external linear guide or a guided cylinder to protect the rod bearing from bending moments. When replacing an existing unit, match bore (40 mm), stroke (750 mm), PT1/4 port thread, TC centre trunnion mounting, and the non-magnetic piston configuration.
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 theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC40 tie-rod cylinder with matching stroke, PT ports, and TC trunnion mount.
