Product Description
NM50-265 Polyurethane Rubber Coupling For Pump, Fan, Compressor, Vehicle
NM50-265 coupling, rubber coupling, polyurethane coupling for pumps, fans, compressors, vehicles, and transporting equipment.
Product Overview
"NM rubber coupling spider" and "NM rubber element" refer to the elastomer components of NM-type rubber couplings. These couplings consist of two cast iron half-couplings and an intermediate rubber elastomer designed for efficient power transmission and vibration absorption.
Structure and Composition
  • Consists of two cast iron half-couplings and an intermediate rubber elastomer
  • Rubber elastomer features spider-like shape with multiple claw structures
  • Made from specially designed synthetic rubber such as nitrile rubber (NBR)
  • Steel cores inserted in teeth for enhanced durability and performance
Key Features and Advantages
  • Excellent elasticity and shock absorption for vibration reduction
  • Superior oil resistance and corrosion resistance
  • High wear resistance for long service life
  • Easy installation and maintenance
  • Compensates for axial, radial, and angular shaft misalignment
  • Economical and practical for various applications
  • Quiet and smooth operation
  • Suitable for high torque and intermittent operation
Application Fields
  • Pump equipment: centrifugal pumps, gear pumps, screw pumps
  • Fan equipment: centrifugal fans, axial fans
  • Compressors: air compressors, refrigeration compressors
  • Transportation equipment: conveyors, elevators, cranes
  • Industrial equipment: mixers, crushers, reducers, printing machines, textile machines
Technical Specifications
  • CE certificate compliant
  • Full quality detection before delivery
  • OEM services available
  • Rich experience in precision casting
