The AirTAC Airtac SC40 Standard Cylinder SC40X1090S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1090mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1090S is a double-acting single-rod pneumatic cylinder with a 40 mm bore and a non-standard 1090 mm stroke, built for applications needing extended reach. It delivers 628 N of push force at 0.5 MPa and 1130 N at 0.9 MPa, powered by a 16 mm diameter piston rod.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback. The adjustable air cushion at each end decelerates the piston over 21 mm to reduce impact, and the PT1/4 port threads connect to standard pneumatic fittings.

The 1090 mm stroke moves components between distant conveyor lines or workstations, with the built-in magnet confirming full extension and retraction.
Applies a bead of adhesive along a 1090 mm path. The sensor magnet provides position verification at each end of the long travel to ensure cycle completion.
Opens and closes a large slide gate on a hopper or chute. The 1130 N force at 0.9 MPa handles heavy granular materials, while sensors confirm the gate is fully open or closed.
For a 40 mm bore, the SC40X1090S provides 628 N at 0.5 MPa. If your load requires more force, stepping up to the 50 mm bore (SC50) increases push force to 982 N at the same pressure. If your force requirement is lower, the 32 mm bore (SC32) offers 402 N.
This 1090 mm stroke exceeds the standard maximum of 1200 mm for the 40 mm bore, making it a made-to-order item. For strokes of this length, side loading on the 16 mm rod is a critical consideration. An external linear guide or a guided cylinder configuration is strongly recommended to prevent rod bending, uneven seal wear, and premature bearing failure. When replacing this cylinder, match five points: 40 mm bore, 1090 mm stroke, PT1/4 port thread, the built-in magnet (-S), and your current mounting accessory.
Quick checklist
At the standard 0.5 MPa operating pressure, 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.
The 1090 mm stroke is non-standard and requires a made-to-order request. The -S suffix in the model code means this cylinder has a built-in magnet. You can mount CMSG (reed) or DMSG/EMSG (solid-state) sensors directly on the tie-rod barrel to detect the piston position without any additional mounting bands.
