  • High wear resistance maintains performance during long-term, frequent use.
  • Easy installation with simple structure enables quick maintenance and reduces downtime.
  • Misalignment compensation accommodates axial, radial, and angular deviations.
  • Made from high-quality synthetic rubber (NBR/CSM/SBR) with 80 Shore A hardness for durability.
  • Available in standard sizes from NM50 to NM265 with custom sizes upon request.
  • CE certified with comprehensive quality inspection and OEM services available.
FAQs:
  • What materials are used in the NM rubber coupling?
    The NM rubber coupling is made from high-quality synthetic rubber, typically nitrile rubber (NBR), CSM, or SBR, providing excellent durability and resistance properties.
  • What types of misalignment can this coupling accommodate?
    The NM rubber coupling effectively compensates for axial, radial, and angular misalignments between connected equipment shafts.
  • In which industrial applications is this coupling commonly used?
    This coupling is widely used in pump equipment (centrifugal, gear, screw pumps), fan equipment, compressors, transportation equipment, and various industrial machinery including mixers and crushers.
  • What are the temperature limits for this polyurethane coupling?
    The NM rubber coupling can operate at working temperatures up to 100°C while maintaining its performance characteristics.
