What is a water pump bearing:

• Water pump bearings are designed to support large axial loads but can also support moderate radial loads

• They incorporate an improved internal design that enables it to operate at high speeds

• These bearings have self-aligning characteristics

• This is because the outer ring raceway is spherical and the center of the radius is located on the bearing axis

Features

• Unlike other double row bearings, water pump bearing do not have an inner ring but have raceways which are machined directly into the surface

• This enables them to have more space available for the rolling elements hence improve its load carrying capabilities

• Due to its design, it is possible to use a suitable combination of both ball and roller rows economically

Advantages:

• Our water pump bearings can support heavy loads and are easy to install because they come as ready to fix units

Bearing types available at DEMY:

• They mainly consist of standard two row bearings and are of two types

• Ball-ball-these water pump bearing have two rows of balls and are used for moderate loads

• This design is simplest and most eco-friendly

• They include WIB, BWF, WS , WK,885000 series and more

• Ball-roller-these water pump bearing have one row of balls and one row of rollers which enables them to support more load. Include WIR, WN, WKH, 665000 series and more

Composition:

• The basic composition of water pump bearing is follows:

  • Shaft, which are mainly made of induction hardened steel

  • Roller elements wets, which refer to either two rows of balls or one row of balls and one row of rollers

  • Outer ring, which is usually made of hardened steel

Water pump bearings incorporate a spherical outer ring raceway, with the center of the radius located on the bearing axis, providing a self-alignment capability

This bearing incorporates a 45° contact angle that enables the bearing to support large axial loads and moderate radial loads

These bearings incorporate an improved internal design that allows relatively high-speed operation
