LJ22530M Lovejoy Jaw Coupling Hub 30 mm Bore

AR LJ22530M Lovejoy L225 Jaw Coupling Hub Overview

The AR LJ22530M is a Lovejoy L225 jaw coupling hub with a 30 mm bore, engineered by Annovi Reverberi to deliver precise torque transfer, superior alignment, and long-term vibration control in industrial pump and motor assemblies. Built from high-strength steel, this heavy-duty hub provides the durability and accuracy needed for continuous-duty systems operating under high torque and variable loads.

LJ22530M Key Features

• Compatible with Lovejoy L225 coupling components
• Precision-machined 30 mm bore for accurate shaft fit
• High-strength steel construction for maximum durability
• Corrosion-resistant finish for harsh environments
• Three-jaw interlocking design for balanced torque transmission
• Requires elastomer spider insert (sold separately)

Performance Benefits

• Provides precise, efficient torque transfer under heavy load
• Reduces vibration and mechanical noise
• Protects bearings, seals, and shafts from misalignment stress
• Absorbs shock loads and torsional vibrations when paired with a spider insert
• Maintains alignment stability during high-speed and high-torque operation
• Fail-safe design allows limited operation even if the spider wears

Coupling System Function

• Forms a flexible mechanical connection when paired with a matching hub and spider
• Eliminates metal-to-metal contact for quieter operation
• Compensates for angular, axial, and parallel misalignment
• Ensures even load distribution across all jaws
• Promotes smooth torque flow throughout the drive assembly

Construction & Material Advantages

• High-strength steel body ensures exceptional durability and fatigue resistance
• Precision machining improves fit, balance, and torque distribution
• Corrosion-resistant coating supports long service life in demanding environments
• Rigid structure maintains concentricity and prevents runout

LJ22530M Applications

• Hydraulic power units
• Industrial cleaning equipment
• Compressors and blowers
• Pumps and motor assemblies
• Manufacturing and processing machinery
• General industrial power transmission systems

Installation & Maintenance

• Slides onto keyed shafts and secures with a set screw
• No lubrication required for clean, maintenance-free operation
• Spider insert can be replaced without removing hubs or altering alignment
• Minimal downtime during service or inspection
• Routine checks of the spider ensure continued vibration control and torque efficiency
