The AirTAC Airtac SC40 Standard Cylinder SC40X700CB 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 SC40X700CB is a double-acting single-rod pneumatic cylinder with a 40 mm bore and 700 mm stroke, delivering a push force of 628 N at 0.5 MPa. Its 16 mm diameter rod and PT1/4 port thread suit moderate-force clamping, pressing, and positioning tasks where a pivoting mount is required.
This model features a rear double clevis (CB) mount, allowing the cylinder body to pivot during operation to accommodate angular misalignment. The adjustable air cushion at each end decelerates the piston smoothly over a 21 mm stroke, reducing end-cap impact. As a genuine AirTAC tie-rod cylinder, it provides reliable performance in industrial automation.

Pivots a mechanical linkage on agricultural equipment, with the CB clevis allowing the cylinder to swing as the linkage moves through its arc.
Operates a pivoting diverter gate on a conveyor line, where the rear clevis mount lets the cylinder body align with the gate's changing angle.
Drives a pivoting clamp arm in a welding fixture, using the CB mount to accommodate the arm's rotation during clamping and release.
The SC40X700CB uses a CB rear double clevis for pivoting applications; ensure the mating bracket matches the 40 mm bore. For higher force, the SC50 series offers 982 N push at 0.5 MPa. At 700 mm stroke, the 16 mm rod may be susceptible to bending under side load—consider an external guide or a guided cylinder if the load is not purely axial. When replacing, match bore, stroke, PT port thread, CB mount, and the absence of a magnet.
Quick checklist
At 0.5 MPa air pressure, 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 CB rear double clevis is integral to this model. For rigid mounting, choose a basic (no mount) or LB foot mount variant. The clevis allows the cylinder body to pivot, so a rigid mount would over-constrain it.
