The AirTAC Airtac SC40 Standard Cylinder SC40X1065S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1065mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1065S is a double-acting tie-rod cylinder with a 40 mm bore and a non-standard 1065 mm stroke, exceeding the 1200 mm maximum standard stroke for this bore family. It delivers 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa operating pressure, driven by a 16 mm diameter piston rod with M12x1.25 male threads.
The built-in magnet (-S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. With a body length A of 142 mm, the total extended length is approximately 1207 mm, and the adjustable air cushion (21 mm) decelerates the piston smoothly at each end of the stroke.

The 1065 mm stroke pushes or pulls components across wide conveyor gaps, with the built-in magnet confirming end-of-stroke position.
Operates sliding safety gates or diverters on packaging lines, where the long stroke and sensor feedback ensure full open/close verification.
Moves pallets or totes across roller beds in logistics hubs, using the 16 mm rod and adjustable cushion for controlled, repeatable motion.
Choose the SC40 when 628 N at 0.5 MPa covers your load; step up to the SC50 bore for 982 N if you need more force, or down to the SC32 for 402 N in a lighter assembly. This 1065 mm stroke is non-standard—confirm lead time with your AirTAC distributor.
For strokes over 300 mm, a long unsupported rod can bend under side load. Use an external linear guide or switch to a guided cylinder if the load is not perfectly axial. When replacing an existing unit, match five points: 40 mm bore, 1065 mm stroke, PT1/4 port thread, the built-in magnet (-S), and basic mounting (no bracket).
Quick checklist
At 0.7 MPa supply pressure, the 40 mm bore generates 879 N of push force and 528 N of pull force on the retract stroke, based on the official AirTAC thrust table.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so mounting dimensions differ. Only replace another AirTAC SC40 tie-rod cylinder with matching bore, stroke, PT1/4 ports, and magnet option.
