Bell Gossett Bg 189105LF Bearing Assembly Pr LD-3 HD-3

Product Description

The BELL GOSSETT BG 189105LF is a lead-free bearing assembly designed for use in hydronic heating pump systems. Bearing assemblies support the pump shaft, reduce rotational friction, and maintain alignment between the impeller and motor. This unit is built for the PR, LD-3, and HD-3 series pump platforms and is available in cast iron or bronze construction depending on the model configuration. Lead-free compliance makes it suitable for installations where low-lead material standards apply. Technicians performing pump rebuilds or scheduled maintenance will find this part a direct-fit replacement for the supported series.

This bearing assembly is used in heating system pump applications across the PR, 2.5 inch, LD-3, and HD-3 series pump lines. These pump families are commonly installed in residential and commercial hydronic heating systems, including hot water circulation and closed-loop heating loops. The cast iron or bronze model options allow selection based on system fluid compatibility and installation requirements.
