Norgren M/31081 Air Bellow - Frictionless operation
Part Number: M/31081
Quick Summary
Air bellow M/31081 by Norgren delivers frictionless single-acting actuation for high-force linear motion in automation setups. Engineers frequently contend with maintenance-heavy cylinders, lubrication needs, and wear from vibration. While the data sheet does not list formal certifications, this design aligns with common industry expectations for CE-style compliance, robust vibration isolation, and non-magnetic construction when used in compliant systems. By combining no-lubrication operation with compact dimensions and a high theoretical force, M/31081 reduces downtime and simplifies integration in compact automation cells.

FAQs
M/31081 uses a G1/2 port and standard 230 x 230 mm footprint with a 175 mm height. It is designed for simple on-frame mounting and provides a single-acting, high-force stroke of 75 mm. Ensure compatibility with your actuation plane and frame clearance before integration.
The unit operates from 0 to 8 bar (0 to 116 psi) and withstands temperatures from -40 to 70 °C (-40 to 158 °F). This makes it suitable for harsh industrial environments and temperature-variant applications without extra cooling or enclosure requirements.
Yes, it offers high vibration isolation and frictionless operation, with no lubrication needed. This reduces maintenance cycles and lowers contamination risk in sensitive environments like food processing or electronics assembly.
The provided data does not list specific certifications. Verify with the supplier for CE marking, IP protection class, and SIL readiness as applicable to your jurisdiction and safety program when integrating into compliant systems.
The frictionless, no-lubrication design plus straightforward installation reduces maintenance labor and downtime. Its high-force short-stroke capability enables reliable actuation in tight spaces, contributing to longer mean time between failures (MTBF) and lower lifecycle costs.
