LJ100SOX-B Lovejoy Jaw Coupling Insert BLUE

LJ100SOX-B

L100 blue Lovejoy jaw coupling insert

• AR LJ100SOX-B is a blue Lovejoy-style L100 series jaw coupling insert
  engineered by Annovi Reverberi for flexible, vibration-damping torque transmission in
  professional-grade pump and motor systems.
• Functions as the elastomer “spider” between two metal hubs, transmitting power
  efficiently while absorbing shock loads, vibration, and minor shaft misalignment.
• Helps protect rotating equipment—including pumps, motors, bearings, and seals—
  to extend overall system life and reduce unplanned downtime.
• Color-coded blue compound indicates a medium-stiffness material that balances
  torque capacity with excellent vibration absorption.

Design & Construction

High-performance blue elastomer compound

• Constructed from a high-performance blue elastomer that combines strength,
  elasticity, and durability for long service life in demanding industrial environments.
• Precision-molded geometry fits accurately within L100-series coupling jaws,
  maintaining alignment and uniform load distribution in all operating conditions.
• Material is engineered to resist fatigue, compression set, and chemical degradation
  even when exposed to temperature swings, moisture, detergents, and cleaning agents.
• Non-conductive and corrosion-resistant properties make it suitable for wet,
  chemically aggressive, or washdown environments where metal components may degrade.

Performance & Protection

Vibration damping, misalignment & torque cushioning

• Provides exceptional flexibility and vibration damping, reducing mechanical
  noise and torsional shock throughout the drive system.
• Absorbs torque spikes and transient loads during start-up, shutdown, or load
  changes, helping prevent damage to pumps, motors, and connected equipment.
• Compensates for small angular, parallel, and axial misalignments between hubs,
  reducing stress on bearings, seals, and shafts.
• Maintains stable, balanced rotation at high speeds and high torque, supporting
  smooth, quiet operation in continuous-duty or frequent start-stop applications.

Installation & Maintenance

Modular, lubrication-free coupling insert

• Designed to be installed between two L100-series Lovejoy hubs; torque is
  transmitted through elastic compression of the spider.
• Lubrication-free design keeps operation clean and simplifies service—no grease
  or oil required for the coupling.
• Replacement is quick and tool-light: technicians simply separate the hubs enough to remove the
  old insert and drop in a new LJ100SOX-B, typically without removing hubs or
  realigning shafts.
• Lovejoy-style fail-safe geometry allows metal jaws to remain partially engaged
  if the insert deteriorates, providing limited operation until scheduled maintenance.
• Routine maintenance consists of periodic visual inspections for cracks,
  hardening, or wear and timely insert replacement to restore full damping capability.

LJ100SOX-B Applications

Where the LJ100SOX-B is used

• Industrial and commercial pressure washers where smooth pump–motor coupling and
  vibration control are critical.
• Hydraulic power units and drives requiring flexible, shock-absorbing couplings
  between motors and pumps.
• Compressors, blowers, and general industrial machinery operating under variable
  loads or frequent start-stop cycles.
• Manufacturing and process equipment where reduced noise, improved efficiency,
  and longer bearing life are priorities.
• Suitable for both indoor and outdoor installations in harsh environments thanks
  to its chemical resistance and wide operating temperature range.
