The AirTAC Airtac SC40 Standard Cylinder SC40X900TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 900mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X900TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (up to 1130 N at 0.9 MPa). With a 40 mm bore and a 900 mm stroke, it features a 16 mm diameter piston rod and PT1/4 ports. The adjustable pneumatic cushion (21 mm length) decelerates the piston smoothly at end-of-travel, reducing impact and noise.
This model includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (part code F-SC40TC), allowing the cylinder to pivot freely during operation. The body length A is 142 mm, giving a total extended length of approximately 1042 mm. Standard TPU seals provide a reliable operating temperature range of -20 to +70 °C.

The 900 mm stroke and pivoting trunnion mount suit long-reach diverter arms on packaging lines, where the cylinder must swing to redirect products between lanes.
Combines a long linear stroke with a centre pivot to raise and tilt bins or totes at assembly workstations, using the 628 N force to handle moderate payloads.
Moves a clamp head along a 900 mm beam in edge-banding or sawing machines. The adjustable cushion protects the tooling from impact at the end of each rapid advance.
Select the SC40X900TC when your application requires a 40 mm bore with a pivoting mounting style. For higher force, step up to the 50 mm bore (SC50 series, 982 N push at 0.5 MPa); for a lighter, more compact solution, the 32 mm bore (SC32, 402 N push at 0.5 MPa) may suffice. The 900 mm stroke is a long extension for a 16 mm rod—ensure the load is guided externally to prevent rod bending or bearing side-load damage.
For a direct replacement, match these five points: 40 mm bore, 900 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting accessory, and the absence of a built-in magnet. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder provides 628 N of push force and 528 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. These values are based on the 40 mm bore and 16 mm rod diameter.
A 900 mm stroke with a 16 mm rod is susceptible to bending under side loads. It is strongly recommended to use an external guide rail or rod support to absorb lateral forces. The cylinder's rod bearing is designed for axial thrust, not transverse loading.
