LJ100118 Lovejoy Jaw Coupling Hub 1-1/8 inch Bore | L100 Series

LJ100118 Lovejoy Jaw Coupling Hub 1-1/8 inch Bore | L100 Series

• AR LJ100118 is a precision-engineered Lovejoy-style jaw coupling hub from the L100 series with a 1-1/8″ precision-machined bore.
• Designed by Annovi Reverberi to deliver smooth, balanced, vibration-reducing torque transmission in high-performance pump and motor systems.
• Provides a secure mechanical connection that maintains shaft alignment and protects critical components under continuous-duty operation.
• Ideal for pressure washers, hydraulic systems, compressors, manufacturing equipment, and other demanding industrial drives.

Construction & Materials

• Manufactured from high-strength steel for superior resistance to fatigue, mechanical stress, and deformation.
• Corrosion-resistant finish stands up to water, cleaning chemicals, and humid or harsh environments.
• 1-1/8″ bore is precision-machined for a tight fit on the shaft, minimizing fretting and micro-movement.
• Includes keyway and set screw provision to secure the hub and prevent slippage during high torque transmission.
• Steel body provides rigidity and strength without unnecessary bulk, allowing installation in compact mechanical layouts.

LJ100118 Lovejoy L100 Jaw Design

• Classic three-jaw interlocking geometry connects two hubs via a flexible elastomer spider (sold separately).
• Spider element provides critical damping: absorbs vibration, cushions shock loads, and compensates for minor misalignment.
• Jaw faces are precision-machined to ensure perfect engagement with the mating hub for balanced, low-backlash operation.
• Fail-safe jaw profile allows limited continued operation even if the elastomer insert wears, supporting uptime until scheduled maintenance.

Performance & Misalignment Handling

• Engineered to transfer high torque while minimizing mechanical noise and vibration, improving operator comfort and equipment life.
• Accommodates angular, parallel, and axial misalignment that naturally occurs in rotating equipment.
• Reduces load on bearings, seals, and shafts, helping maintain alignment and extend service intervals for connected pumps and motors.
• Handles high loads, frequent start-stop cycles, and temperature variations typical of industrial duty cycles.

Installation & Maintenance

• Simple installation: LJ100118 position hub on the shaft, align the key, tighten the set screw, and insert the elastomer spider between the two hubs.
• Modular design allows quick disassembly and spider replacement without disturbing shaft alignment, minimizing downtime.
• Requires no lubrication; routine care is limited to periodic visual inspection of the elastomer insert for wear or degradation.
• Dimensional tolerances are tightly controlled by Annovi Reverberi to ensure compatibility with standard L100-series spiders and mating hubs.

Typical Applications

• Pressure washer power units – couples electric motors or engines to high-pressure pumps.
• Hydraulic power packs – connects drive motors to hydraulic pumps in mobile or stationary systems.
• Compressors and blowers – dampens vibration between motors and rotating elements.
• Manufacturing and process equipment – conveyor drives, mixers, and general industrial machinery.

Why Choose the AR LJ100118?

• Combines the proven LJ100118 Lovejoy L100 jaw coupling design with Annovi Reverberi’s high manufacturing standards.
• Provides smooth, low-vibration torque transfer that protects pumps, motors, and drivetrain components.
• Offers long-term stability in systems subject to shock loads, frequent cycling, and thermal expansion.
• Delivers maintenance-free, clean operation with only simple spider inspections required.
• Preferred by technicians, engineers, and OEMs who demand accurate fit, strength, and long service life from their couplings.
