Lovejoy 68514412296 Flexible Hub Coupling 1.5 in Bore

Product Description

The LOVEJOY 68514412296 is a flexible hub coupling designed for power transmission applications in industrial and mechanical drive systems. With a maximum bore diameter of 1.5 inches and an outer diameter of 4.5 inches, this coupling accommodates shaft connections where minor misalignment, vibration damping, or torque flexibility is required. The overall assembled length is 4.88 inches. Constructed from sintered iron, it delivers the structural rigidity expected in demanding rotary drive environments. This coupling is typically installed by millwrights, mechanical contractors, or industrial maintenance technicians working on motors, pumps, compressors, and similar rotating equipment.

This flexible hub coupling is suited for use in residential and commercial mechanical systems wherever a flexible drive connection is needed between a motor shaft and a driven component. The L190 coupling size code and 5000 RPM maximum speed rating make it appropriate for a range of mid-speed rotary applications. It is sold individually and ships as a single hub, which is the standard configuration for replacement and new-installation scenarios where only one hub requires service.

Key Features

• Maximum bore diameter of 1.5 inches accommodates common motor and pump shaft sizes
• 4.5 inch outer diameter and 4.88 inch overall length for compact drive train fitment
• Sintered iron construction provides durability in continuous-duty rotary applications
• Rated to 5000 RPM maximum for reliable mid-speed power transmission
• Coupling size code L190 for straightforward cross-reference and replacement sourcing

Compatibility

Designed as an OEM-style replacement or new-installation flexible hub coupling suitable for motors, pumps, compressors, and other rotating equipment that accept L190 series flexible couplings with up to 1.5 inch bore shafts.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before removing or installing any coupling components. Ensure shaft surfaces are clean and free of burrs before pressing or fitting the hub, and verify bore and keyway dimensions match the application shaft before assembly. Follow applicable ANSI and OSHA lockout/tagout procedures throughout the service procedure.
