  • Designed for 4RD16 in-line circulating pumps

Bearing Assembly for 4RD16 Pumps

This cast-iron bearing assembly is built for Bell & Gossett Series 100 NFI in-line circulating pumps. It fits equipment identified by Grainger part 4RD16 and manufacturer model 106189. The part number is 118844 and the unit ships new.

Direct replacement with included seal

The assembly arrives as a complete seal bearing unit, so no separate seal kit is required. Installation follows the standard pump teardown procedure for Series 100 NFI models. The main risk is damaging the new bearing races if the old shaft is scored or if the housing bore is out of round.

Handles Series 100 NFI circulating loads

The cast-iron construction matches the original rating for Series 100 NFI in-line circulators. It supports the radial and axial loads those pumps generate in hydronic heating and cooling loops. It will not suit larger frame sizes or pump series outside the 100 NFI family.
