Lovejoy 69790405246 Grid Coupling Spring Alloy Steel Size 1040

Product Description

The LOVEJOY 69790405246 is a universal grid coupling spring designed as the spring-only replacement component for grid-style flexible couplings. Made from alloy steel, this grid spring transmits torque between connected shafts while absorbing shock loads and dampening vibration in rotating equipment. It fits coupling size code 1040, with a coupling size of 2.94 inches. Rated for up to 2000 inch-pounds of torque and a maximum speed of 6000 RPM, it suits demanding power transmission applications. Millwrights, industrial mechanics, and maintenance technicians install this component during scheduled coupling service or after grid element wear.

This grid spring is used in industrial power transmission systems where flexible grid couplings connect motors, pumps, compressors, conveyors, and similar rotating equipment. It is a direct replacement spring element for coupling size 1040 housings, including applications referencing part G2040. It is suited for both horizontal and vertical shaft installations in light to medium industrial environments where shock absorption and misalignment tolerance are required.

Key Features

• Coupling size code 1040 with a coupling size of 2.94 inches
• Rated torque capacity of 2000 inch-pounds
• Maximum operating speed of 6000 RPM
• Spring-only design allows component-level replacement without full coupling disassembly
• Fits coupling housings referencing part G2040

Compatibility

Designed as a replacement grid spring for LOVEJOY size 1040 grid couplings, including applications that reference coupling part G2040. Confirm housing size code before ordering.

Installation Notes

Installation is typically performed by a millwright or qualified industrial mechanic. De-energize and lock out all connected equipment before beginning coupling service per applicable LOTO procedures. The grid spring element should be inspected for wear or fatigue at regular maintenance intervals and replaced as a set when significant wear is observed. Consult the coupling manufacturer's service documentation for proper grid installation and lubrication requirements.
