Lovejoy 68514436848 Flexible Coupling Sleeve Hytrel

Product Description

The LOVEJOY 68514436848 is a one-piece solid sleeve insert designed for use with JE-series flexible jaw couplings. Made from Hytrel, a flexible polyester elastomer, this sleeve transmits torque between two coupling hubs while absorbing shock and dampening vibration. It accommodates bore diameters from 0.625 inches up to 1.625 inches and carries a rated torque of 2,875 inch-pounds (324.83 N/m). At 2.19 inches in overall length and 4.34 inches in outside diameter, it fits the Series JE coupling envelope. Licensed mechanical contractors, millwrights, and industrial maintenance technicians are the typical installers.

This sleeve is used in light-to-medium industrial drive applications where two shafts must be coupled with a degree of flexibility. Common installations include pump-to-motor connections, conveyor drives, and compressor drives in both commercial and industrial settings. The Hytrel material provides resistance to oil, heat, and moderate chemical exposure, making it suitable for mechanical rooms, equipment pads, and light-duty process environments. It is sold individually.

Installation Notes

Installation is typically performed by a licensed millwright or mechanical technician. De-energize and lock out the drive motor before removing or installing any coupling component per OSHA lockout/tagout requirements. Ensure both hub bores are clean and free of burrs before seating the sleeve. Do not exceed the rated torque for the coupling size when selecting this sleeve for an application.
