The AirTAC Airtac SC40 Standard Cylinder SC40X805S is a genuine double-acting standard air cylinder with a Ø40mm bore and 805mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X805S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 805 mm stroke is a made-to-order length exceeding the standard 1200 mm maximum for the 40 mm bore, providing extended reach for specialized linear motion tasks.
This model features a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The 16 mm diameter piston rod and adjustable air cushion at each end ensure smooth deceleration, while the PT1/4 port and M12x1.25 rod thread maintain standard connectivity.

The 805 mm stroke moves components between distant conveyor stations, with the magnetic piston enabling end-of-stroke confirmation via barrel-mounted sensors.
Directs product flow on wide packaging lines. The adjustable cushion absorbs impact at high cycle rates, protecting the 16 mm rod and end caps.
Provides extended clamping reach for large weldments or assemblies, where the non-standard stroke avoids the need for complex mechanical linkages.
Choose the SC40 bore when your application needs a balance of compactness and force, delivering 628 N at 0.5 MPa. If you require higher thrust, stepping up to the SC50 bore provides 982 N at the same pressure. For this 805 mm stroke, which is non-standard and exceeds typical catalog lengths, ensure the 16 mm rod is adequately supported against side loads—consider an external linear guide if the load is not purely axial.
To replace an existing cylinder, match five key points: 40 mm bore, 805 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 628 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so dimensions are not interchangeable. It replaces another AirTAC SC40 cylinder or a tie-rod cylinder with matching bore, stroke, PT1/4 ports, and magnetic piston.
