Lovejoy 68514412294 Flexible Hub Coupling 1-3/8 in Bore

Product Description

The LOVEJOY 68514412294 is a flexible hub coupling designed to connect rotating shafts while accommodating minor misalignment in mechanical drive systems. With a maximum bore diameter of 1-3/8 inches and an overall outside diameter of 4-1/2 inches, this coupling fits a range of mid-torque drive applications. The overall assembled length measures 4.88 inches. Constructed from sintered iron, the hub delivers solid load-bearing performance in industrial and mechanical service environments. It carries a size code of L190 and is rated for speeds up to 5000 RPM. Millwrights, maintenance technicians, and mechanical contractors are the primary trades who specify and install this type of coupling.

This flexible hub coupling is suited for use in pumps, compressors, conveyor drives, fans, and other rotating equipment where shaft-to-shaft connection with some flex tolerance is required. The L190 size code places it in a common mid-range coupling family used across light industrial and commercial mechanical systems. It is typically paired with a matching spider insert and mating hub to complete the coupling assembly. Verify bore size and hub series compatibility before installation.

Key Features

• Maximum bore diameter of 1-3/8 inches accommodates common mid-range shaft sizes
• 4-1/2 inch outside diameter suits mid-torque drive applications
• Overall assembled length of 4.88 inches for standard drive train spacing
• Sintered iron construction provides strength and wear resistance
• Rated up to 5000 RPM for higher-speed drive applications
• L190 coupling size code for straightforward cross-reference and replacement

Compatibility

Designed as an OEM-style replacement flexible hub coupling for mechanical drive assemblies requiring an L190 series hub with a maximum bore of 1-3/8 inches.

Installation Notes

Installation is typically performed by millwrights or qualified mechanical technicians. Always de-energize and lockout the drive system before removing or installing coupling components. Ensure shaft and bore surfaces are clean and free of burrs before pressing or keying the hub onto the shaft. The coupling assembly requires a compatible spider insert and mating hub — do not operate the coupling without all assembly components fully seated.
