The AirTAC Airtac SC40 Standard Cylinder SC40X135S is a genuine double-acting standard air cylinder with a Ø40mm bore and 135mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X135S is a double-acting single-rod pneumatic cylinder with a 40 mm bore and 135 mm stroke, delivering 628 N of push force at 0.5 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration, while the body length A of 142 mm keeps the envelope compact for tie-rod construction.
The built-in magnet, designated by the -S suffix, allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for non-contact position sensing. Operating on filtered air from 0.15 to 1.0 MPa with standard PT1/4 ports, this cylinder suits automated sequences where mid-stroke or end-of-stroke confirmation is required.

The built-in magnet and 135 mm stroke suit conveyor gate or stop applications where CMSG/DMSG sensors confirm the gate position at each cycle, ensuring precise material flow control.
Providing 628 N of push force at 0.5 MPa, this SC40X135S cylinder is ideal for small pneumatic presses, clinching fixtures, or insertion tools where sensor feedback verifies tool contact.
The adjustable cushion and magnet-based position sensing make this cylinder a good fit for laboratory test rigs and life-cycle testers that require a compact, repeatable 135 mm linear stroke.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N push at 0.5 MPa. If space is a constraint, the 32 mm bore SC32 delivers 402 N. This 135 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore. When replacing an existing unit, match bore, stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration to ensure drop-in compatibility with another AirTAC SC tie-rod cylinder.
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 reaches 1130 N.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG, DMSG, or EMSG sensors can be clamped directly onto the barrel to detect piston position without external brackets or flags.
