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.
