The AirTAC Airtac SC40 Standard Cylinder SC40X200CB is a genuine double-acting standard air cylinder with a Ø40mm bore and 200mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X200CB is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration across the 200 mm stroke, making it a reliable workhorse for medium-duty linear tasks.
This model features a rear double clevis (CB) mount, allowing the cylinder body to pivot during operation and absorb misalignment. The body length A is 142 mm, giving a total extended length of approximately 342 mm. It uses standard PT ports (PT1/4) and operates on filtered air from -20 to +70 °C with default TPU seals.

The rear clevis pivot allows the cylinder to drive oscillating linkages on agricultural equipment like chute diverters or bale handlers without binding.
Pivots a diverter gate on a conveyor line. The 200 mm stroke provides ample travel to swing the gate fully open or closed for sorting packages.
Operates a pivoting clamp arm on a welding fixture. The double clevis mount handles the arcing motion, while the adjustable cushion reduces impact at the end of the clamping stroke.
For applications needing more force, stepping up to the SC50 bore provides 982 N of push at 0.5 MPa. If space is tight and the load is lighter, the SC32 bore offers 402 N. The CB rear double clevis is ideal for pivoting applications where the cylinder must swing through an arc.
To ensure a correct replacement, match five points: 40 mm bore, 200 mm stroke, PT1/4 port thread, the CB rear double clevis mounting accessory (F-SC40CB), and the absence of a built-in magnet. At 200 mm, this stroke is well within the standard range, so no additional side-load concerns typically apply for purely axial loads.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC40 cylinder with matching stroke, port, and CB mounting.
