PU Coupling

PU Couplings are high-performance elastomeric components used in flexible shaft coupling assemblies. Designed to absorb shock, vibration, and minor misalignment in mechanical systems, PU couplings help reduce wear on connected components and ensure smoother power transmission. Manufactured using premium-grade polyurethane, these couplings provide a superior balance of flexibility, toughness, and chemical resistance—making them ideal for demanding applications across multiple industries.

Key Features:

  • High Elasticity & Flexibility: Compensates for angular, parallel, and axial misalignments between shafts.
  • Excellent Shock & Vibration Absorption: Protects gearboxes, motors, and other components from dynamic loads and torque spikes.
  • Durable & Wear-Resistant: Long service life even under continuous, high-load operation.
  • Chemical & Oil Resistant: PU resists degradation from lubricants, oils, and common industrial solvents.
  • Quiet Operation: Damps noise and reduces metal-to-metal contact.

Common Types:

  • Jaw-Type PU Spider Couplings: Interlocking hub and spider design—standard in most motor and pump assemblies.
  • HRC Couplings: For medium-duty power transmission with easy installation.
  • Gear Coupling Inserts: Polyurethane gear profiles that fit between steel hubs.
  • Tyre & Pin Bush Couplings (PU elements): Used in flexible disc-type couplings.

Applications:

  • Pumps and compressors
  • Gearboxes and conveyors
  • Hydraulic machinery
  • Textile and packaging machines
  • Industrial mixers and agitators
  • HVAC equipment
  • Machine tools and robotics
