The AirTAC Airtac SC40 Standard Cylinder SC40X900SN is a genuine double-acting standard air cylinder with a Ø40mm bore and 900mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X900SN is a double-acting pneumatic cylinder with a 40 mm bore and a 900 mm stroke, delivering a push force of 628 N at 0.5 MPa (up to 1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for precise position feedback.
This model is configured with NBR (nitrile) seals, offering a balanced cost-performance ratio for general industrial environments within the standard -20 to +70 °C temperature range. The body length A is 142 mm, resulting in a total extended length of approximately 1042 mm. As a tie-rod cylinder, it is shorter than an ISO 15552 profile, making it suitable for installations where space is limited.

Ideal for medium-duty pusher stations on packaging lines, using its 900 mm stroke to transfer cartons between conveyor lanes. The built-in magnet enables end-of-stroke sensing for automated sequencing.
Provides the consistent linear motion needed for adhesive or sealant dispensing heads. The NBR seals are compatible with standard shop air, and the 16 mm rod offers good rigidity for the 900 mm reach.
Suitable for operating vertical lift gates on chutes or hoppers, where the double-acting function provides positive control in both directions. The adjustable cushion softens the impact at the top and bottom of the stroke.
For applications requiring slightly less force, consider stepping down to the 32 mm bore (402 N at 0.5 MPa). If higher force is needed, the 50 mm bore provides 982 N at the same pressure. With a 900 mm stroke, this cylinder has a significant unsupported rod length. To prevent rod bending and premature seal wear, especially under any side load, use an external guide rail or a guided cylinder assembly.
When replacing an existing unit, ensure a 5-point match: 40 mm bore, 900 mm stroke, PT port thread, NBR seal material, and the presence of a built-in magnet (-S suffix) for sensor compatibility. This ensures the replacement fits the existing mounting, plumbing, and control system without modification.
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 AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke. It is a direct replacement only for another AirTAC SC tie-rod cylinder with matching bore, stroke, PT ports, NBR seals, and a built-in magnet.
