Lovejoy 68514435450 Flexible Solid Sleeve Epdm 1-1/8 in

Product Description

The LOVEJOY 68514435450 is a flexible one-piece solid sleeve coupling designed for shaft-to-shaft power transmission applications. Constructed from Ethylene Propylene Diene Monomer (EPDM), this sleeve insert provides vibration dampening and misalignment compensation between coupled shafts. It accepts a minimum bore diameter of 1.125 inches and measures 3.44 inches in overall length with a 7.06-inch outside diameter. With a rated torque capacity of 2,875 in/lb (422 N/m), it is suited for moderate to demanding drive applications. Mechanical technicians and millwrights install this part as a direct sleeve component within Series 10 jaw-style coupling assemblies.

This sleeve is used in industrial and commercial drive systems where flexible coupling connections are required. The one-piece solid sleeve design simplifies replacement compared to multi-piece configurations and is appropriate for pump drives, conveyor systems, compressor connections, and similar rotating equipment. It is sized for Series 10 coupling hubs and is sold individually.

Key Features

• One-piece solid sleeve construction simplifies installation and replacement
• EPDM material provides resistance to heat, ozone, and moderate chemical exposure
• Rated torque of 2,875 in/lb (422 N/m) for reliable power transmission
• 1.125-inch minimum bore diameter accommodates standard Series 10 coupling hubs
• 3.44-inch overall length and 7.06-inch outside diameter for precise dimensional fit
• Sleeve insert style for use with jaw-type coupling hub assemblies

Compatibility

Designed for use with LOVEJOY Series 10 jaw-style coupling assemblies requiring a one-piece solid sleeve insert with a 1.125-inch minimum bore diameter.

Installation Notes

Installation should be performed by a qualified mechanical technician or millwright. Disconnect and lock out all power to the drive system before removing or installing coupling components. Ensure both coupling hubs are properly aligned before seating the sleeve to avoid premature wear. Follow applicable ANSI and OSHA machine guarding requirements when reassembling drive components.
