The AirTAC Airtac SC32 Standard Cylinder SC32X690 is a genuine double-acting standard air cylinder with a Ø32mm bore and 690mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X690 is a double-acting tie-rod cylinder with a 32 mm bore and a 690 mm non-standard stroke, built for applications requiring an extended reach in a compact envelope. At 0.5 MPa it provides 402 N of push force and 345 N of pull force, while at the maximum operating pressure of 0.9 MPa the thrust reaches 724 N, driven by a 12 mm diameter piston rod.
This model features a 140 mm body length (dimension A) and 21 mm of adjustable air cushion at each end to decelerate the load smoothly. The PT1/8 ports and M10x1.25 rod thread are standard, and the cylinder operates on filtered air from -20 to +70 °C with its default TPU seals. Because the 690 mm stroke exceeds the 1000 mm maximum standard stroke for bore 32, this unit is a made-to-order configuration.

The 690 mm stroke reaches across wide conveyor gaps to push or divert small packages, leveraging 402 N of force at standard shop air.
Operates flapper gates on compact sorting lines where a long, slender cylinder fits in tight machinery spaces.
Opens and closes lightweight ventilation dampers in agricultural buildings, using the extended 690 mm stroke for full louver travel.
Choose the SC32 when your force requirement aligns with its 402 N push at 0.5 MPa; if you need more force, step up to the SC40 which delivers 628 N at the same pressure. For this 690 mm stroke, the rod is relatively long compared to its 12 mm diameter, so avoid direct side loads—use an external linear guide or a guided cylinder variant if the load is not perfectly axial.
When replacing an existing cylinder, match five points: 32 mm bore, 690 mm stroke, PT1/8 port thread, the basic (no bracket) mounting configuration, and the absence of a magnet. This SC32X690 is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
No, the 12 mm rod is not designed for unsupported side loads at this extended length. You must use an external linear guide rail or replace it with a guided cylinder to prevent rod bending and premature seal wear.
