The AirTAC Airtac SC40 Standard Cylinder SC40X1750S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1750mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1750S is a double-acting, single-rod pneumatic cylinder with a 40 mm bore and an extended 1750 mm stroke. This model delivers a theoretical push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa, making it suitable for long-reach actuation tasks.
This specific non-standard stroke length exceeds the standard maximum of 1200 mm for the 40 mm bore, requiring a made-to-order configuration. The cylinder features a 16 mm diameter piston rod, PT1/4 port connections, and an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly. The integrated '-S' magnet allows direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for reliable end-of-stroke detection.

Ideal for pushing boxes or products off a wide conveyor line where a 1750 mm stroke is needed to fully traverse the belt width, with sensors confirming full extension and retraction.
Moves a dispensing head along a long gantry axis. The built-in magnet provides precise position feedback to the PLC, ensuring adhesive is applied accurately over a large area.
Used in custom durability test machines to apply a consistent 628 N load over a long 1750 mm travel distance, with the adjustable cushion protecting the cylinder and test fixture at end-of-stroke.
Select the SC40X1750S when your application requires a long, 1750 mm linear reach with a force of around 628 N at standard plant pressure. If your load demands more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N of push force at 0.5 MPa. For a shorter standard stroke within the 1200 mm limit, the SC40X1000 is a readily available alternative.
For this 1750 mm stroke, side loading on the 16 mm rod is a critical design factor. An unsupported long stroke rod is susceptible to bending and bearing wear under any lateral force. You must guide the load externally with a linear rail system or integrate a guided cylinder to ensure the rod moves purely in an axial direction. When replacing this cylinder, ensure the new unit matches the 40 mm bore, 1750 mm stroke, PT1/4 port thread, basic mounting, and the integrated magnet for sensor compatibility.
Quick checklist
The theoretical output force at 0.5 MPa is 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. Actual dynamic force will be slightly lower due to friction.
A 1750 mm stroke on a 16 mm rod is highly susceptible to buckling and side-load damage. The load must be externally guided on a separate linear rail or bearing system. The cylinder rod should only be used to push or pull the load, not to support its weight or absorb lateral forces.
