LJ10058 Lovejoy Jaw Coupling 5/8 inch Bore | L100 Series

L100 jaw coupling hub, 5/8 in. bore with 5/32 in. keyway

• AR LJ10058 is a Lovejoy L100 series jaw coupling hub
  with a 5/8-inch bore and 5/32-inch keyway, engineered by Annovi Reverberi for
  precise, vibration-damping torque transmission in pumps, motors, and industrial drive systems.
• Built for reliability, balance, and long service life, it provides secure
  alignment, smooth power transfer, and protection against wear and mechanical shock
  in demanding applications.
• Commonly specified for high-pressure pumps, hydraulic power units,
  compressors, and industrial cleaning equipment requiring consistent torque
  and stable operation.

Design & Construction

High-strength steel hub with precision-machined bore

• LJ10058 Manufactured from high-strength steel for exceptional durability,
  dimensional accuracy, and resistance to fatigue under continuous-duty operation.
• 5/8-inch precision-machined bore provides a snug, concentric fit
  on compatible shafts to minimize runout and vibration.
• Integrated 5/32-inch keyway and set screw create a positive
  mechanical lock that prevents shaft slippage and preserves alignment under load.
• Compact, balanced hub geometry performs efficiently in confined equipment bays
  while maintaining access for inspection and service.
• Corrosion-resistant surface finish supports reliable operation in environments
  exposed to water, detergents, and temperature variations.

Coupling Function & Protection

Lovejoy three-jaw design with elastomer spider (sold separately)

• Utilizes the proven Lovejoy three-jaw LJ10058 L100 profile, transmitting
  torque through an elastomer spider insert (sold separately).
• Elastomer element cushions torque spikes and shock loads, helping
  protect motors, pumps, bearings, and seals from premature wear.
• Coupling assembly compensates for angular, parallel, and axial
  misalignment, maintaining smooth power transfer even in real-world mounting conditions.
• Precision-machined jaws ensure smooth engagement and uniform load
  distribution across the insert, reducing backlash and mechanical noise.
• Fail-safe Lovejoy design keeps metal jaws partially engaged if
  the insert deteriorates, allowing limited operation until maintenance is completed.

Performance & Applications

Balanced, low-vibration torque transmission

• Tight machining tolerances and balanced construction deliver
  low-vibration, low-noise rotation across a wide speed range.
• Robust steel body provides high torque capacity and long-term
  stability in both high-speed and high-torque environments.
• Suitable for stationary and mobile systems, including
  pressure-washer skids, hydraulic drives, and industrial cleaning machines.
• By reducing misalignment stress and vibration, the hub helps
  extend bearing life, reduce shaft fatigue, and improve overall system stability.

Installation & Maintenance

Simple setup with low ongoing service needs

• Installation is straightforward: slide the hub onto the 5/8 in. keyed shaft,
  align the key, position axially, and tighten the set screw to lock in place.
• Complete the coupling by adding a matching L100 companion hub and elastomer spider
  between the jaws.
• No lubrication is required; routine care consists of periodic visual
  inspection of the elastomer insert for cracking, wear, or hardening.
• Inserts are inexpensive and quickly replaced without removing the hubs or disturbing
  shaft alignment, minimizing downtime.
• Corrosion-resistant finish and robust steel construction keep the hub in service
  across many insert changes for a long, low-maintenance service life.
