Lovejoy 69790405461 Flexible Hub Coupling Alloy Steel

Product Description

The LOVEJOY 69790405461 is an alloy steel flexible hub coupling designed to connect rotating shafts in mechanical drive systems while accommodating minor misalignment and reducing vibration transmission. With a maximum bore diameter of 7/8 inches and an outer diameter of 1.88 inches, this coupling fits the 1020 coupling size code. Rated to 6000 RPM, it is suited for moderate- to high-speed drive applications in HVAC equipment, pumps, compressors, and general industrial machinery. Licensed millwrights, HVAC mechanics, and maintenance technicians are the typical installers.

This flexible hub coupling is used in residential and light commercial mechanical drive applications where shaft coupling flexibility is required to compensate for angular or parallel misalignment. The 1020 size code makes it a common replacement or upgrade component in belt-drive and direct-drive assemblies found in fan systems, blower assemblies, and pump drive trains. Its alloy steel construction provides durability in demanding service environments.

Key Features

• Maximum bore diameter of 7/8 inches accommodates a range of shaft sizes up to that dimension
• Outer diameter of 1.88 inches fits compact drive assemblies
• Rated to 6000 RPM for moderate- to high-speed applications
• Alloy steel construction for strength and wear resistance
• 1020 coupling size code for straightforward replacement identification
• Flexible hub design reduces vibration and shock load transmission between shafts

Compatibility

Designed as an OEM-style replacement flexible hub coupling for mechanical drive systems requiring a 1020 size code coupling with a maximum bore of 7/8 inches and an outer diameter of 1.88 inches.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before beginning work, following OSHA lockout/tagout procedures. Ensure shaft diameters do not exceed the 7/8 inch maximum bore before pressing or keying the hub onto the shaft. Do not operate the coupling above its 6000 RPM rating, and verify alignment is within the coupling's allowable tolerance after installation.
