The AirTAC Airtac SC40 Standard Cylinder SC40X950 is a genuine double-acting standard air cylinder with a Ø40mm bore and 950mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X950 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a long 950 mm stroke. At 0.5 MPa it generates 628 N pushing force and 528 N pulling force, rising to 1130 N push at the 0.9 MPa maximum operating pressure, making it suitable for medium-duty linear transfer and lifting tasks.
This model features a 16 mm diameter piston rod with M12x1.25 male threads, PT1/4 ports, and an adjustable air cushion of 21 mm at each end to decelerate the piston quietly. The body length A is 142 mm, giving a total extended length of approximately 1092 mm. TPU seals provide a standard operating temperature range of -20 to +70 °C.

The 950 mm stroke moves components between distant conveyor stations or work cells, with adjustable cushioning protecting the tooling at both ends of travel.
Delivers smooth, controlled linear motion for adhesive or sealant dispensing heads across a wide workpiece, using the 628 N force to maintain steady tool pressure.
Pushes cartons or totes off a main line onto a spur conveyor. The 16 mm rod and tie-rod construction handle repetitive cycling in distribution centre environments.
Choose the SC40 bore when your application needs around 628 N of push force at standard plant pressure; stepping up to the SC50 delivers 982 N, while the SC32 provides 402 N for lighter loads. At 950 mm stroke the unsupported rod is long relative to its 16 mm diameter—evaluate side loads carefully and consider an external linear guide or a guided cylinder if the rod tip sees any radial force.
For replacement, match five points: 40 mm bore, 950 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder produces 628 N extending and 528 N retracting. At 0.7 MPa it reaches 879 N push, and at the maximum operating pressure of 0.9 MPa it delivers 1130 N push. The theoretical maximum at 1.0 MPa is 128 kgf, but AirTAC rates operation only up to 1.0 MPa.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an equivalent ISO 15552 profile cylinder. It will only drop in as a replacement for another AirTAC SC tie-rod cylinder of the same bore, stroke, port thread, and mounting configuration.
