Tb Woods TB-WE3H118 WE3 Flexible Coupling Shaft Hub

Product Description

The TB Woods TB-WE3H118 is a WE3 series flexible coupling shaft hub designed for power transmission applications in industrial and mechanical drive systems. This Type BTS hub features a 1-1/8 inch bore with a 1/4 inch wide by 1/8 inch deep keyway for secure shaft engagement. Constructed from steel, it provides the durability required for demanding drive applications. With a 2.32 inch outer diameter and a 1-1/2 inch overall length, the hub is compact and suited for installations where space is a consideration. Licensed mechanics and industrial maintenance technicians install this component as part of a complete WE3 flexible coupling assembly.

This shaft hub is used in industrial drive applications where flexible couplings are required to transmit torque between shafts while accommodating minor misalignment. Typical installations include pump drives, fan drives, compressor drives, and general-purpose power transmission equipment in both light industrial and commercial mechanical systems. The hub mates with the corresponding WE3 coupling element and mating hub to complete the assembly.

Key Features

• 1-1/8 inch bore for direct shaft mounting
• 1/4 inch x 1/8 inch keyway width and depth for positive shaft engagement
• 2.32 inch outer diameter hub fits WE3 series coupling assemblies
• 1-1/2 inch overall length for compact installation
• Steel construction for strength and durability in power transmission service
• Type BTS designation for correct series identification and parts matching

Compatibility

Designed as a WE3 series flexible coupling shaft hub for use in standard industrial power transmission drive assemblies requiring a 1-1/8 inch bore and Type BTS configuration.

Installation Notes

Installation is typically performed by qualified mechanical or industrial maintenance technicians. De-energize and lock out the drive system before beginning any coupling work in accordance with applicable OSHA lockout/tagout procedures. Ensure the shaft and bore are clean and free of burrs before pressing or sliding the hub into position. Do not use the coupling to correct gross shaft misalignment beyond the rated tolerance of the WE3 coupling element.
