The AirTAC Airtac SC40 Standard Cylinder SC40X650S is a genuine double-acting standard air cylinder with a Ø40mm bore and 650mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X650S is a double-acting pneumatic cylinder with a 40 mm bore and 650 mm stroke, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 16 mm diameter piston rod provides robust linear guidance, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for precise end-of-stroke detection.
This model features a body length A of 142 mm and an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly. The PT1/4 port and M12x1.25 rod thread ensure standard pneumatic connectivity. As a genuine AirTAC tie-rod cylinder, it is factory-tested for reliable operation in automation tasks.

The 650 mm stroke and 628 N push force at 0.5 MPa efficiently actuates diverter gates on packaging lines, sorting products by size or weight with sensor-confirmed positioning.
Provides consistent clamping force for medium-duty CNC jigs. The built-in magnet allows easy integration of reed switches to verify clamp engagement before machining starts.
Delivers the long 650 mm reach needed to push cartons onto a pallet stack. The adjustable cushion absorbs impact at the end of stroke, protecting the pusher plate and product.
For applications requiring higher force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa. If a more compact footprint is needed, the 32 mm bore SC32 series offers 402 N. At this 650 mm stroke, ensure the rod is protected from side loads; consider an external linear guide or a guided cylinder variant to prevent rod bending and premature seal wear.
When replacing an existing cylinder, match five key points: 40 mm bore, 650 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting configuration. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. It is a direct dimensional match only for another AirTAC SC series cylinder with the same 40 mm bore, 650 mm stroke, PT ports, and magnet option.
