The AirTAC Airtac SC40 Standard Cylinder SC40X170 is a genuine double-acting standard air cylinder with a Ø40mm bore and 170mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X170 is a double-acting pneumatic cylinder delivering a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and a 170 mm stroke, its 16 mm diameter piston rod provides robust linear actuation for medium-duty tasks, while the adjustable air cushion at each end decelerates the piston smoothly over the final 21 mm to reduce end-cap impact.
This tie-rod cylinder features a compact body length of 142 mm (A dimension), making the total extended length approximately 312 mm. It uses PT1/4 ports and an M12x1.25 rod thread. The standard TPU seals provide reliable operation in ambient temperatures from -20 to +70 °C, and the design is rated for a proof pressure of 1.5 MPa.

The 170 mm stroke and 628 N push force efficiently actuate gates or pushers to divert cartons on a packaging conveyor, with the adjustable cushion softening the shift at high cycle rates.
Ideal for holding workpieces in place during drilling or welding. The 16 mm rod provides good rigidity, and the consistent double-acting motion ensures reliable clamping and release.
Use this cylinder as a pallet stop on gravity or powered roller conveyors. Its tie-rod construction is serviceable, and the force is sufficient to halt medium-weight loads without damage.
Select the SC40X170 when your application requires a push force around 628 N at standard plant air pressure. If you need more force, stepping up to the SC50 bore delivers 982 N at the same 0.5 MPa. For precise position sensing, specify the -S magnet option to allow CMSG or DMSG sensors to mount directly on the barrel.
To ensure a direct replacement, match five key points: 40 mm bore, 170 mm stroke, PT1/4 port thread, the specific mounting accessory (if any), and the magnet option. The SC40 is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 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 reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than a standard ISO 15552 cylinder. It is not dimensionally interchangeable. You must match it with another AirTAC SC tie-rod cylinder of the same bore, stroke, and port configuration.
