Lovejoy 69790405178 Horizontal Coupling Seal Kit

Product Description

The LOVEJOY 69790405178 is an alloy steel universal seal kit designed for horizontal coupling assemblies. It provides a sealing solution that protects the internal coupling components from contamination and lubricant loss, extending service life in rotating power transmission applications. The kit is sized for coupling size code 1040, with a coupling size of 4.63 inches and a torque capacity of 1200 inch-pounds. It is rated for speeds up to 6000 RPM. Mechanical and maintenance technicians working on coupled shaft assemblies install this seal kit as part of routine service or when replacing worn seals on horizontal jaw or sleeve-type couplings.

This seal kit is suited for industrial and commercial power transmission installations where horizontal coupling configurations are used. Typical applications include motor-to-pump assemblies, conveyor drives, compressor drives, and similar coupled rotating equipment. The kit ships as a single package quantity, making it appropriate for single-coupling service jobs. It is compatible with coupling assemblies requiring a size 1040 horizontal seal configuration, and the alloy steel construction provides durability in demanding mechanical environments.

Compatibility

Designed to fit coupling part G2040 and compatible with size 1040 horizontal coupling assemblies requiring a universal seal kit replacement.

Installation Notes

Installation should be performed by a qualified mechanical or maintenance technician. De-energize and lock out all power to the drive system before disassembling any coupling components, following LOTO procedures per applicable safety standards. Inspect the coupling hub and sleeve for wear or damage before installing the new seal kit. Do not exceed the rated torque capacity or maximum RPM of the coupling assembly after reassembly.
