Lovejoy 68514435454 Flexible Solid Sleeve Hytrel 1-1/8 in

Product Description

The LOVEJOY 68514435454 is a flexible one-piece solid sleeve coupling insert designed for shaft-to-shaft power transmission applications. Made from Hytrel, a durable thermoplastic elastomer, this sleeve insert fits between jaw-style coupling hubs to dampen vibration and absorb shock loads. It carries a rated torque capacity of 11,350 inch-pounds, making it suitable for demanding drive systems in industrial and mechanical service environments. The sleeve measures 7.06 inches in outside diameter and 3.44 inches in overall length. Licensed HVAC, mechanical, and industrial technicians install this component during coupling assembly or replacement on rotating equipment.

This sleeve insert is sized for a minimum bore diameter of 1.125 inches and is classified as a Series 10 coupling element. It is suited for use in pumps, blowers, compressors, and similar rotating equipment where flexible coupling assemblies are required. The Hytrel material performs across a broad temperature range and resists oils and many industrial fluids, making it appropriate for mechanical rooms, equipment pads, and light industrial installations where standard jaw couplings are already in use.

Compatibility

Designed as an OEM-style replacement sleeve insert for Series 10 jaw-style flexible coupling assemblies requiring a 1.125 inch minimum bore diameter and a 7.06 inch outside diameter element.

Installation Notes

This sleeve insert is installed by qualified mechanical or HVAC technicians during coupling assembly or scheduled maintenance. De-energize all connected equipment and lock out the drive system before disassembling the coupling. Inspect mating jaw hubs for wear or damage before seating the new sleeve. Consult applicable mechanical and local codes for proper coupling alignment procedures on rotating equipment.
