Taco brg-a-100 Pro-fit Bearing Assembly Replacement

Product Description

The TACO brg-a-100 is a heavy-duty Pro-Fit bearing assembly designed as a direct replacement for Bell Gossett and Armstrong seal and bearing assemblies in hydronic circulation systems. Built with die cast aluminum or cast iron construction, the assembly ensures proper alignment with the motor shaft to extend bearing life and reduce premature wear. The unit features bronze-fitted internals, a stainless steel faceplate, and a stainless steel shaft, making it suitable for both open and closed hydronic system applications. Licensed HVAC technicians and plumbers working on commercial or residential hydronic systems install this assembly during pump rebuilds or seal replacements.

This bearing assembly falls within the universal A-through-D size range of the Pro-Fit lineup, which is engineered to consolidate inventory by reducing the number of SKUs needed to cover a broad range of pump configurations. It is appropriate for use in hydronic heating and cooling systems where Bell Gossett or Armstrong circulator pumps require seal and bearing service. The bronze-fitted, stainless steel shaft construction makes it compatible with both open and closed loop piping systems.

Key Features

• Die cast aluminum or cast iron construction for durability and proper motor shaft alignment
• Stainless steel shaft and faceplate for corrosion resistance in wet system environments
• Bronze-fitted internals suitable for open and closed hydronic system applications
• Universal sizing (A thru D range) reduces inventory SKU requirements for service technicians
• Designed as a drop-in replacement for Bell Gossett and Armstrong seal and bearing assemblies

Compatibility

Designed as an OEM-style replacement for Bell Gossett and Armstrong seal and bearing assemblies, covering universal size range A through D configurations in hydronic circulator pump applications.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with hydronic pump service. Shut down the system and relieve all pressure before disassembling the pump casing or removing the existing bearing assembly. Ensure the motor shaft is clean and free of debris before seating the new assembly to maintain proper alignment. Follow all applicable local codes and manufacturer service procedures when completing the repair.
