ISB water pump bearings are simple and affordable; they can have either two rows of ball bearings or one row of ball bearings and one row of roller bearings, each well-spaced to ensure a longer life and their capacity to withstand higher radial loads.
The bearing is pre-lubricated with water-repellent grease which eliminates the need for maintenance, and is subjected to a special heat treatment during its production.
