IMI Norgren PM/31043 Air Bellow - 5750 N Force
Part Number: PM/31043
Quick Summary
Air bellow PM/31043 delivers frictionless, high-force piston action for short-stroke applications in automation and packaging. Engineers often battle downtime caused by lubrication requirements and wear in traditional actuators, which slows lines and increases maintenance costs. This unit is designed for minimal upkeep, offering frictionless operation with no maintenance or lubrication and high vibration isolation to protect sensitive equipment. While industry-standard considerations like CE marking, IP protection, and SIL safety integration are important, confirm the appropriate certifications for your region with your supplier. The aluminium body and compact installation simplify retrofits, while the 4-1/2 inch diameter and 100 mm stroke deliver predictable performance in confined spaces, supporting reliable, high-throughput automation.

Frictionless operation reduces wear and maintenance, delivering longer service intervals and lower lifecycle costs for high-cycle pneumatic lines. This translates to fewer unplanned downtime events in packaging, robotic transfer, and fixture-clamping tasks. The PM/31043’s 5750 N theoretical force enables rapid actuation and reliable load handling, improving cycle times and part accuracy in pressing, forming, and material handling applications. Its single-acting design and compact footprint simplify integration into tight control cabinets, robot cells, and automated lines where space is at a premium. A non-magnetic aluminium body minimizes interference with nearby sensors and actuators, supporting robust system performance in mixed-signal environments. Standard 0 to 8 bar operating pressure and G3/8 port size align with common plant air systems, reducing integration effort and procurement complexity. The 100 mm stroke and three convolutions deliver controlled, repeatable motion suitable for precise positioning and vibration isolation in CNC, packaging, and assembly equipment.

FAQs
PM/31043 uses standard G3/8 ports and a compact aluminium body. Ensure current from your plant air line is 0-8 bar and that fittings match G3/8 dimensions. Align the actuator for straight-line travel, mount using compatible brackets, and verify clearances around the 100 mm stroke to prevent binding during operation.
The PM/31043 is designed for high-vibration isolation with a rigid aluminium body and frictionless operation. In vibration-prone setups such as milling, grinding, or palletizing, expect stable stroke, reduced sensor interference, and improved repeatability, thanks to its robust single-acting design and compact form factor.
Yes. Its short 100 mm stroke with a 4-1/2 inch diameter provides strong, repeatable actuation for clamping, transfer, and indexing tasks. The low-maintenance, lubrication-free operation minimizes downtime on high-speed packaging lines, while the 0-8 bar operating range matches typical plant air systems.
PM/31043 is designed for frictionless operation with no maintenance or lubrication, reducing ongoing upkeep. Regular checks should include ensuring air supply cleanliness, inspecting mounting hardware, and confirming no external damage to the aluminium body or ports to maintain consistent performance.
Verify a 0 to 8 bar operating pressure, a G3/8 port size, 4-1/2 inch nominal diameter, and a 100 mm stroke with three convolutions. The unit delivers up to approximately 5750 N of theoretical force and uses a non-magnetic aluminium body, suitable for sensor-rich automation environments.
