Product Description
NM50-265 Polyurethane Rubber Coupling for Pump, Fan, Compressor, and Vehicle Applications
The NM rubber coupling spider and NM rubber element are key components of NM-type rubber couplings, consisting of elastomer (spider rubber ring) and rubber elements designed for efficient power transmission and vibration absorption.
Structure and Composition
- Comprises two cast iron half-couplings with an intermediate rubber elastomer
- Spider-shaped rubber elastomer with multiple claw-like structures for secure connection
- Made from high-quality synthetic rubber (typically nitrile rubber/NBR) for durability
Key Features and Benefits
- Superior shock absorption: Reduces equipment vibration and noise while extending service life
- Excellent resistance: Oil, acid, alkali, and chemical corrosion resistant for harsh environments
- High wear resistance: Maintains performance during long-term, frequent use
- Easy installation: Simple structure enables quick maintenance and reduces downtime
- Misalignment compensation: Accommodates axial, radial, and angular deviations
