The AirTAC Airtac SC40 Standard Cylinder SC40X810S 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 AirTAC SC40X810S is a double-acting single-rod tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at the 0.9 MPa max operating pressure). Its 810 mm stroke falls well within the 1200 mm maximum standard stroke for the 40 mm bore, making this a standard-configuration actuator.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. The 16 mm diameter piston rod features an M12x1.25 male thread, PT1/4 ports, and an adjustable air cushion (21 mm cushion length) to decelerate the piston quietly at end of travel. Body length A is 142 mm, giving an extended length of approximately 952 mm.

The 810 mm stroke and magnetic piston allow precise end-of-stroke sensing for diverting or stopping medium-weight packages on conveyor lines, with sensor feedback confirming gate position.
Provides 628 N at 0.5 MPa for pressing components into fixtures. The built-in magnet enables multi-position sensing to verify full extension and retraction in automated assembly cells.
Ideal for pushing tall bins or totes off accumulation zones in warehouse automation. The 810 mm stroke reaches across wide roller beds, and the adjustable cushion reduces impact noise at end of travel.
Choose the SC40 bore when your application needs around 628 N of push force at standard 0.5 MPa shop air. If you require more force, step up to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 bore provides 402 N. At 810 mm stroke, the rod is long and unsupported side loads can cause bending or premature bearing wear—always guide the load externally or use a guided cylinder when lateral forces are present.
For direct replacement, match these five points: 40 mm bore, 810 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor mounting, and the basic (no bracket) mounting configuration. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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, push force reaches 1130 N. These values are based on the 40 mm bore and 16 mm rod diameter.
Yes. The -S suffix in SC40X810S indicates a built-in magnet on the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without additional brackets.
