Lovejoy 68514436184 Flexible Coupling Hub 2-3/8 in Bore

Product Description

The LOVEJOY 68514436184 is a flexible coupling hub designed for power transmission applications in industrial and mechanical drive systems. With a maximum bore diameter of 2.375 inches and a keyway measuring 0.625 inches wide by 0.3125 inches deep, this hub accepts a keyed shaft for positive torque transfer. The overall diameter is 7.5 inches and the overall length is 5.69 inches. Constructed from cast iron, it delivers the rigidity and wear resistance required in demanding drive train installations. Licensed mechanics and industrial maintenance technicians are the typical installers for this component.

This flexible coupling hub is suited for use in pump drives, compressor drives, fan drives, and general-purpose rotating equipment where shaft misalignment tolerance is needed. The size code 10S designation places this hub within a specific coupling series, allowing it to be paired with a matching hub and a flexible spider or grid element to complete the coupling assembly. It is appropriate for both light industrial and heavy-duty mechanical systems operating within the rated speed range.

Key Features

• Maximum bore diameter of 2.375 inches accommodates a range of shaft sizes up to that dimension
• Keyway dimensions of 0.625 inches wide by 0.3125 inches deep for positive keyed shaft engagement
• Cast iron construction provides high rigidity and resistance to wear under continuous load
• 7.5 inch OD with 5.69 inch overall length suits larger drive assemblies
• Rated to 3600 RPM maximum for compatibility with standard motor speeds
• Coupling size code 10S for straightforward series matching when selecting mating hubs and flexible elements

Compatibility

Designed as an OEM-style replacement or direct-fit flexible coupling hub for rotating equipment applications requiring a size code 10S hub with a maximum bore of 2.375 inches and cast iron construction. Verify mating hub series and spider or grid element type before installation.

Installation Notes

Installation should be performed by a qualified mechanical technician. De-energize and lock out all power to the drive system before beginning work, following LOTO procedures in accordance with applicable safety standards. Ensure shaft and bore dimensions are confirmed before pressing or driving the hub onto the shaft, and verify keyway alignment before final seating. Do not exceed the 3600 RPM rated maximum speed during operation.
