LJ110158 Lovejoy L110 Jaw Coupling Hub 1-5/8″ Bore

LJ110158

L110 jaw coupling hub, 1-5/8 in bore

• The AR LJ110158 is a heavy-duty Lovejoy L110 jaw coupling hub with a
  1-5/8-inch bore, engineered by Annovi Reverberi for precise, vibration-damping torque
  transmission in industrial pump and motor systems.
• Designed for continuous-duty operation, it delivers smooth, stable power transfer while
  protecting mechanical components from vibration, misalignment, and load fluctuations.
• Ideal for demanding environments such as hydraulic power units, pressure washer assemblies,
  compressors, and manufacturing machinery.
• Provides dependable alignment and long service life in high-torque, high-speed applications.

Design & Construction

High-strength steel Lovejoy L110 geometry

• Built from high-strength steel for exceptional durability, wear resistance, and mechanical
  integrity under heavy torque loads.
• Features the proven Lovejoy three-jaw L110 profile, designed to work with an elastomer
  spider (sold separately) for flexible, shock-absorbing coupling.
• Precision-machined 1-5/8-inch bore fits securely on compatible shafts, while an integrated
  keyway and set screw provide a positive, slip-free mechanical lock.
• Steel body is finished with a corrosion-resistant surface to withstand moisture,
  cleaning chemicals, and harsh operating environments.
• Tight machining tolerances maintain balanced rotation and accurate jaw alignment for
  uniform torque distribution across the elastomer insert.

Performance & Protection

Vibration damping and misalignment compensation

• When paired with an L110 elastomer spider, the hub forms a flexible coupling that cushions torque
  spikes and absorbs vibration, protecting pumps and motors from shock loads.
• Accommodates typical angular, parallel, and axial misalignments between shafts, reducing
  stress on bearings, seals, and shafts.
• Balanced geometry and precise engagement minimize backlash and deliver quiet, stable operation
  across a wide speed range.
• Helps extend the service life of connected equipment by reducing mechanical noise, heat, and
  fatigue in rotating assemblies.

Installation & Maintenance

Simple setup with fail-safe Lovejoy design

• Easy to install: slide the hub onto the keyed shaft, align the key, tighten the set screw,
  and position the elastomer spider between the two hubs.
• No lubrication required—the coupling runs clean and maintenance is limited primarily to
  elastomer inspection and replacement.
• Lovejoy’s fail-safe design allows limited operation even if the spider wears, as the metal
  jaws remain partially engaged to maintain torque transfer until service can be performed.
• Elastomer spider can typically be replaced without removing hubs or realigning shafts,
  minimizing downtime and simplifying field maintenance.

Applications

Where the LJ110158 is used

• Industrial and commercial pressure washer systems coupling electric or engine drives to
  high-pressure pumps.
• Hydraulic power units and fluid-handling systems requiring smooth motor-to-pump power
  transmission.
• Compressors and blowers where vibration reduction and alignment stability are critical.
• Manufacturing and process equipment, including conveyors, mixers, and general rotating
  machinery.
• Any installation needing a compact, high-torque L110 jaw coupling with a 1-5/8-inch bore
  and robust vibration damping.
