Lovejoy 68514441328 Flexible Coupling Hub 28mm Bore

Product Description

The LOVEJOY 68514441328 is a flexible coupling hub designed for use in mechanical power transmission applications where rotational torque must be transferred between shafts while accommodating minor misalignment. This hub features a 28mm maximum bore and an 8mm wide by 3.3mm deep keyway, making it suitable for keyed shaft connections. It measures 2.11 inches in outer diameter and 2.5 inches in overall length, constructed from sintered iron for durability under load. A complete flexible coupling assembly requires two hubs and one spider insert, which are ordered separately. Licensed mechanical contractors and industrial service technicians are the typical installers.

This flexible coupling hub fits rotating equipment in light to medium industrial applications, including pumps, compressors, fans, and conveyor drives. The L095 coupling size code helps identify the correct matching spider and paired hub. With a maximum speed rating of 9000 RPM, it suits a wide range of motor-driven shaft connections in both commercial and industrial settings. Two hubs and one spider must be combined to form a complete functional coupling assembly.

Key Features

• 28mm maximum bore accommodates standard metric shaft sizes
• 8mm x 3.3mm keyway width and depth for keyed shaft engagement
• 2.11 inch outer diameter and 2.5 inch overall length
• Sintered iron construction for load-bearing durability
• Rated to 9000 RPM maximum for high-speed shaft applications
• Coupling size code L095 for matching spider and hub selection

Compatibility

This hub is part of the L095 coupling size family. Two hubs and one spider insert are required for a complete coupling assembly. Compatible spider and hub selections should be matched using the L095 coupling size code.

Installation Notes

Installation is typically performed by a qualified mechanical technician or millwright. Always de-energize and lock out the connected motor or drive before beginning installation. Ensure shaft and bore dimensions are verified before pressing or fitting the hub onto the shaft. Refer to the coupling manufacturer guidelines for proper spider selection and hub spacing to avoid premature wear.
