Lovejoy 68514436181 Flexible Coupling Hub Cast Iron

Product Description

The LOVEJOY 68514436181 is a flexible coupling hub designed for industrial drive applications requiring reliable torque transmission with some allowance for shaft misalignment. Cast from iron, this hub accepts a maximum bore diameter of 2-1/8 inches and features a keyway measuring 1/2 inch wide by 1/4 inch deep, providing a positive mechanical connection to the drive shaft. The hub measures 7-1/2 inches in outer diameter with an overall length of 5.69 inches and is rated to a maximum speed of 3600 RPM. At 10.88 pounds, it is built for heavy-duty service and is installed by industrial mechanics and millwrights in power transmission systems.

This flexible coupling hub is suited for use in industrial machinery, pumps, compressors, fans, and similar rotating equipment where shaft-to-shaft coupling is required. The size code designation 10S identifies its position within the Lovejoy coupling series, allowing pairing with the corresponding spider element and mating hub. It is appropriate for both new installations and replacement service in commercial and light industrial environments where cast iron construction and moderate bore capacity are required.

Key Features

• 1/2 inch by 1/4 inch keyway provides positive keyed shaft engagement
• 7-1/2 inch outer diameter and 5.69 inch overall length suit heavy-duty coupling assemblies
• Cast iron construction for durability in industrial power transmission service
• Rated to 3600 RPM maximum for compatibility with standard motor speeds
• Coupling size code 10S for proper spider and mating hub selection

Compatibility

Designed as an OEM-style flexible coupling hub within the Lovejoy 10S coupling size series, intended for pairing with a compatible spider element and matching mating hub in standard jaw-type flexible coupling assemblies.

Installation Notes

Installation is performed by qualified industrial mechanics or millwrights familiar with power transmission equipment. De-energize and lock out the drive motor before mounting or removing the coupling hub. The bore and keyway should be inspected for proper fit with the shaft and key before assembly. Refer to applicable ANSI and OSHA lockout/tagout procedures during installation and removal.
