The AirTAC Airtac SC40 Standard Cylinder SC40X80CB is a genuine double-acting standard air cylinder with a Ø40mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X80CB is a 40 mm bore, 80 mm stroke double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration for mid-range automation tasks.
This model features a rear double clevis (CB) mounting, part F-SC40CB, allowing the cylinder body to pivot during operation. The standard PT1/4 port thread and TPU seals suit operating temperatures from -20 to +70 °C. The total extended body length is approximately 222 mm.

The rear double clevis mount lets the cylinder swing as it actuates a diverter gate on a packaging line, handling 628 N of force at standard shop air pressure.
Provides consistent 1130 N clamping force at 0.9 MPa for CNC workholding, with the clevis allowing the cylinder to self-align as the clamp engages.
Drives mechanical linkages in material handling equipment where a pivoting mount is needed to follow an arc path, with reliable double-acting control.
Choose the SC40 when 628 N of thrust at 0.5 MPa meets your load requirement. If you need more force, stepping up to the SC50 bore provides 982 N at the same pressure. For strokes of 80 mm, the standard tie-rod construction is rigid, but always align the rod with the load axis to prevent side-load wear on the rod bearing. For replacement, match bore, stroke, PT port thread, CB rear clevis mount, and the non-magnetic specification.
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 reaches 1130 N.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. For a direct dimensional and mounting match, replace only with another AirTAC SC40 cylinder with the same stroke, CB rear clevis, and PT ports.
