The AirTAC Airtac SC40 Standard Cylinder SC40X975S is a genuine double-acting standard air cylinder with a Ø40mm bore and 975mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X975S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 975 mm stroke is within the 1200 mm maximum standard range for the 40 mm bore, making it a standard-configuration unit ready for long-travel linear tasks.
A built-in magnet (-S suffix) allows CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for non-contact position sensing. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/4 port supplies the filtered air required for reliable cycling.

Moves lightweight bins or trays across a 975 mm span in packaging lines, with magnetic sensors confirming full extension and retraction at each cycle.
Drives a dispensing head along a linear rail at moderate speed. The 628 N push force handles the tooling weight, while the adjustable cushion protects the adhesive pattern from end-of-stroke vibration.
Operates a tall lift gate or hopper door in agricultural or bulk-handling equipment. The magnet enables interlock signals to confirm the gate is fully open or closed before conveying starts.
For applications needing less force, the 32 mm bore SC32 series offers 402 N at 0.5 MPa. If the load demands more, stepping up to the 50 mm bore provides 982 N at the same pressure. At 975 mm stroke, the long, unsupported 16 mm rod is susceptible to bending under side loads; an external linear guide or a guided cylinder configuration is strongly recommended to protect the rod bearing and seals.
When replacing an existing cylinder, match five points: 40 mm bore, 975 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This model ships without mounting accessories, so reuse or order the required F-SC40 mounting kit separately.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, push force increases to 1130 N. These values assume clean, filtered air at 40 µm and a stable supply pressure.
Yes. The -S suffix denotes a built-in magnet in the piston, making the barrel compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors. Simply clamp the sensor onto the barrel groove at the desired position to detect stroke end or intermediate points.
