Norgren M/31162 Air Bellow - 65250 N Theoretical Force
Part Number: M/31162
Quick Summary
The Norgren M/31162 air bellow provides frictionless, single-acting actuation for high-force pneumatic applications. Engineers frequently grapple with maintenance, lubrication needs, and vibration that degrade short-stroke performance. This design supports common industry certifications and safety practices, including CE-style compliance, IP-rated ruggedness, and SIL-ready interfaces. Its 16 inch nominal diameter, 315 mm stroke, and 65250 N theoretical force enable decisive motion in compact footprints. With maintenance-free operation and straightforward installation, it reduces downtime and lowers total cost of ownership for automated lines. Designed by IMI Norgren, this actuator integrates with standard G1/2 ports and compatible pneumatic controls for rapid deployment. Whether replacing existing bellows or integrating into a new line, the device offers predictable performance under -40 to 70 C.

Frictionless operation minimizes wear and energy consumption, extending actuator life in high-cycle environments. The business impact is lower maintenance costs and longer mean time between failures on automated lines, with the application ideal for compact pneumatic setups like clamping stations and positioning modules in packaging and pick-and-place systems. No lubrication requirement offers true maintenance-free performance, reducing downtime and lubricant-related contamination, which is particularly valuable in clean or mixed-use environments. The 16 inch diameter, 315 mm stroke and 65250 N theoretical force enable high-load handling within a short stroke, allowing space-constrained installations to improve cycle times and throughput while using standard G1/2 ports and a 0–8 bar air supply. High vibration isolation protects sensors and controls from shocks, aiding precision in stamping and assembly lines; non-magnetic construction further reduces interference with nearby instrumentation. Simple installation and a robust Germany-made design shorten commissioning, enabling quicker startup and reliable operation across the M/31000 range for legacy or new equipment upgrades.

FAQs
Mounting is straightforward thanks to standard G1/2 porting and the 16 inch diameter with a 315 mm stroke. The device accepts typical compressed air supplies from 0 to 8 bar and fits most compact frames without special adapters. Ensure non-magnetic housing remains clear of ferrous interference, and align the actuator with the load path to maximize vibration damping.
The M/31162 delivers a theoretical force of 65,250 N at the 315 mm stroke, with a 16-inch diameter and 2 convolutions. It operates on 0–8 bar air pressure via a G1/2 port. While speed depends on supply and load, the single-acting design provides rapid, decisive movement in short-stroke applications, enhancing cycle time reliability.
Yes, the M/31162 features a high vibration isolation level and a non-magnetic construction, reducing transfer of motion to adjacent sensors and controls. This helps maintain precision in stamping, assembly, and packaging lines. For best results, mount per load path recommendations and verify surrounding ferrous material is minimized to preserve isolation effectiveness.
The data sheet emphasizes industrial robustness and standard operating ranges, with capabilities aligned to common safety and regulatory expectations in pneumatic systems. For your specific region or application, verify CE marking, IP protection level, and SIL compatibility with the control scheme. The unit’s non-magnetic design also supports instrumentation safety near sensitive sensors.
Because the air bellow is maintenance-free with no lubrication requirements, downtime for lubricant changes is eliminated. Its long life, high-force output in a compact package reduces cycle times and improves throughput. When replacing legacy bellows or upgrading lines, the straightforward installation minimizes commissioning time, while the rugged German engineering behind M/31000 family supports predictable lifecycle costs.
