LJ19035M Lovejoy Jaw Coupling Hub 35 mm Bore | Standard L190 Hub

L190 jaw coupling hub, 35 mm bore

• The AR LJ19035M is a Lovejoy L190 jaw coupling hub with a
  35 mm bore, engineered by Annovi Reverberi for precision torque transmission,
  stable alignment, and long-lasting vibration control in high-performance mechanical systems.
• Built from high-strength steel, it delivers the durability, rigidity, and mechanical
  balance required for demanding industrial and commercial power transmission applications.
• Designed to pair with a matching L190 hub and an elastomer spider insert (sold separately)
  to form a flexible coupling that transmits torque while absorbing shock loads and shaft misalignment.

Design & Construction

High-strength steel hub with precision 35 mm bore

• Features a precision-machined 35 mm bore that provides a secure, concentric fit on the shaft
  for smooth torque flow without slippage.
• High-strength steel body is engineered for exceptional fatigue strength and resistance to
  mechanical wear in continuous-duty environments.
• Classic three-jaw Lovejoy L190 configuration engages with the elastomer spider to deliver
  uniform load distribution across all contact surfaces.
• Corrosion-resistant finish protects the hub from moisture, detergents, and harsh cleaning agents for
  dependable indoor or outdoor service.

Performance & Vibration Control

Flexible coupling action for smoother systems

• Jaw-and-spider design reduces vibration, eliminates backlash, and prevents metal-to-metal contact,
  creating a quiet, smooth-running connection.
• Compensates for minor angular, parallel, and axial misalignments that occur in dynamic systems,
  helping maintain steady performance under variable loads.
• Maintains concentricity and balance at high speeds, improving system efficiency and extending
  the life of connected components.
• Helps protect bearings, seals, shafts, pumps, and motors from stress caused by misalignment,
  torque spikes, and vibration.

Installation & Maintenance

Modular, lubrication-free coupling system

• Modular design allows technicians to slide the hub onto the keyed shaft, align it, secure
  with a set screw, and insert the elastomer spider between hubs with no special tools.
• Lubrication-free operation keeps the coupling clean and reduces maintenance requirements in
  hydraulic and industrial cleaning environments.
• Elastomer spider can be replaced without removing hubs or realigning shafts, minimizing
  system downtime during routine service.
• Fail-safe Lovejoy design allows limited torque transmission even if the spider deteriorates,
  as the metal jaws remain partially engaged until maintenance is performed.

Applications

For pumps, hydraulic drives, and industrial machinery

• Ideal for hydraulic power units, industrial cleaning machines, and pressure washer systems
  requiring stable, maintenance-free torque transmission.
• Commonly used in compressors, gearboxes, and rotating equipment where vibration control and
  alignment protection are critical.
• Suitable for medium-to-large power transmission systems that experience frequent starts, stops,
  torque fluctuations, and continuous-duty cycles.
