The AirTAC Airtac SC40 Standard Cylinder SC40X265 is a genuine double-acting standard air cylinder with a Ø40mm bore and 265mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X265 pneumatic cylinder provides a compact 40 mm bore with a 265 mm stroke, generating 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration for medium-duty linear tasks.
With a body length A of 142 mm and PT1/4 ports, this double-acting cylinder is a genuine AirTAC design, built with a tie-rod construction that is shorter than an ISO 15552 profile. It operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C.

Actuates diverter gates on packaging lines, using its 265 mm stroke to reliably push products onto different conveyor lanes at moderate speed.
Provides the 628 N push force needed for light-duty clamping, holding, or pressing of components during assembly or gluing processes.
Opens and closes discharge doors on small hoppers and chutes, handling the repetitive linear motion required for granular material flow control.
For applications needing more force, consider stepping up to the 50 mm bore SC50 series, which offers 982 N at 0.5 MPa. If space is a constraint and less force is acceptable, the 32 mm bore SC32 series provides 402 N. This cylinder is a direct replacement only for another AirTAC SC40 tie-rod unit with matching bore, stroke, PT1/4 ports, and basic mounting.
At a 265 mm stroke, the rod is still well-supported, but always ensure the load is guided externally if any side forces are present to prevent premature rod bearing wear and bending.
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.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so mounting dimensions are not interchangeable. It is a direct dimensional match only for another AirTAC SC40 tie-rod cylinder.
