The AirTAC Airtac SC40 Standard Cylinder SC40X800CA is a genuine double-acting standard air cylinder with a Ø40mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X800CA is a double-acting pneumatic cylinder with a 40 mm bore and an 800 mm stroke, configured with a rear single clevis (CA) mount for pivoting applications. At 0.5 MPa operating pressure, it generates 628 N of push force and 528 N of pull force, making it suitable for medium-duty actuation tasks where the cylinder body needs to articulate.
This model features a 16 mm diameter piston rod with an M12x1.25 rod-end thread and PT1/4 pneumatic ports. The cylinder includes an adjustable air cushion (21 mm cushion length) to decelerate the piston smoothly at the end of its stroke, reducing impact and noise. Its body length A is 142 mm, resulting in a total extended length of approximately 942 mm.

Operates chute diverters or conveyor gates on harvesting equipment, where the rear clevis mount allows the cylinder to pivot freely as the mechanism cycles through its arc of motion.
Pushes lightweight boxes or parts off a conveyor line. The 800 mm stroke provides the reach needed for wide belt systems, while the adjustable cushion protects the product from impact damage.
Drives a pivoting brush or scraper arm across a filter screen. The clevis mount accommodates the swinging motion, and the 40 mm bore supplies sufficient force to overcome debris buildup.
Select the SC40 bore when your application requires a push force around 628 N at 0.5 MPa; if you need more force, step up to the SC50 bore which delivers 982 N at the same pressure. For lighter, more compact needs, the SC32 bore provides 402 N. When replacing an existing cylinder, match five key points: 40 mm bore, 800 mm stroke, PT1/4 port thread, the CA rear single clevis mounting accessory (part code F-SC40CA), and the absence of a built-in magnet.
For this 800 mm stroke, be mindful of side loading. Long, unsupported piston rods are susceptible to bending under lateral forces. If your application involves any off-axis load, use an external linear guide or rod support to prevent premature seal wear and rod bearing damage. The SC40 is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC40 tie-rod units.
Quick checklist
At the standard maximum operating pressure of 1.0 MPa, the theoretical push force is 1256 N. At 0.9 MPa (the typical max operating pressure), it delivers 1130 N of push force. At a common 0.5 MPa line pressure, the push force is 628 N and the pull force is 528 N.
The SC40X800CA comes with a rear single clevis (CA) bracket, part code F-SC40CA, which is designed for pivoting applications. If you need a fixed, surface-mounted installation, you would order the basic model or one with LB foot mounts. The clevis can be removed, but you would need to source the appropriate mounting accessory for your specific mounting style.
