Features

Features 

  • High tensile, shot-peened alloy steel grid springs and precision machined hubs ensure superior coupling performance and long life.
  • Lovejoy’s grid couplings with tapered grids are designed to be interchangeable with other industry standard grid couplings with both horizontal and vertical grid covers.
  • Lovejoy grid couplings are designed for ease of installation and maintenance reducing labor and downtime costs.
  • The torsional flexibility and resilience of Lovejoy grid couplings helps reduce vibration and cushions shock and impact loads.
  • Cover fasteners can be provided in either Inch or Metric sizes.
  • Excellent for use in applications where the equipment is close coupled or spaced apart requiring a spacer style coupling arrangement.
  • Stock spacer designs are available or requests for custom spacer lengths can be addressed by Lovejoy engineering.
