The AirTAC Airtac SC40 Standard Cylinder SC40X175CB is a genuine double-acting standard air cylinder with a Ø40mm bore and 175mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X175CB 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 and 175 mm stroke suit medium-duty linear actuation where a pivoting rear mount is required.
This model features a rear double clevis (CB) mounting, part F-SC40CB, allowing the cylinder to pivot during operation. The 16 mm diameter piston rod provides good column strength, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact.

Operates pivoting linkages on agricultural equipment such as chute diverters or hitch mechanisms, where the rear clevis allows the cylinder to swing freely.
Pushes or pulls diverter gates on material handling conveyors. The clevis mount accommodates the arcing motion of the gate arm without binding.
Provides the clamping force in welding or assembly fixtures where the cylinder body must pivot as the clamp arm engages and disengages the workpiece.
For higher force, step up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If a lower force is acceptable, the 32 mm bore offers 402 N. The CB rear clevis mount is ideal for applications where the cylinder body needs to articulate. When replacing an existing unit, match the bore, 175 mm stroke, PT port thread, and ensure the rear double clevis mounting style is duplicated. For strokes over 300 mm, consider external guides to protect the rod from side loading.
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 increases to 1130 N.
Yes, the CB suffix indicates a rear double clevis mount, which is specifically designed for applications where the cylinder needs to pivot. The mounting accessory code is F-SC40CB.
