The AirTAC Airtac SC40 Standard Cylinder SC40X700SCA is a genuine double-acting standard air cylinder with a Ø40mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X700SCA is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and 700 mm stroke, it uses a 16 mm diameter piston rod and PT1/4 ports, making it a capable mid-range actuator for linear motion tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a rear single clevis mount (CA) for pivoting applications. The total extended body length is approximately 842 mm (body length A of 142 mm + 700 mm stroke), with an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly.

The 700 mm stroke and rear clevis mount allow this cylinder to pivot a diverter gate on a packaging or sorting conveyor, directing products between lanes with the 628 N push force at standard line pressure.
With the CA rear clevis, the cylinder body can swing as it extends, ideal for actuating a pivoting clamp or hold-down arm on a welding or assembly fixture, using the full 700 mm reach.
Controls a large hopper door or directional chute on agricultural processing equipment. The magnet allows end-of-stroke sensors to confirm full open/close positions in dusty environments.
The SC40X700SCA suits applications needing the 628 N force class of a 40 mm bore. If your load requires more force, stepping up to a 50 mm bore (SC50) provides 982 N at 0.5 MPa. For lighter, faster cycles, a 32 mm bore (402 N) may be a better fit. At 700 mm stroke, the 16 mm rod is unsupported beyond the front bearing; any side load will cause bending and premature seal wear. Use an external linear guide or a guided cylinder to absorb transverse forces and protect the rod.
For direct replacement, match these five points: 40 mm bore, 700 mm stroke, PT1/4 port thread, rear single clevis mounting (CA, using bracket F-SC40CA), and the built-in magnet (-S) for sensor compatibility.
Quick checklist
At the standard operating pressure of 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 increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
It is a direct replacement for an AirTAC SC40X700SCA or a tie-rod cylinder with identical specifications: 40 mm bore, 700 mm stroke, PT1/4 ports, rear single clevis (CA) mount, and a built-in magnet for sensors. It is not dimensionally interchangeable with ISO 15552 profile cylinders.
