Busch Ball Bearing Part# 473000262 – vacstellar

Description

Ball bearings are the elegant solution. They use rolling elements—hardened steel balls—to separate the moving parts. The shaft is attached to the bearing’s inner ring. The pump housing holds the outer ring. The balls roll in between.

This simple idea has a huge impact. Rolling creates far less resistance than sliding. This drastically reduces friction, heat, and power loss This isn’t a  hardware store bearing. Part #473000262 is the official Busch replacement component. It’s manufactured to the exact size, tolerance, and material specification required for your specific pump model.
