Production Description:
Water pump bearing OEM WB01083, L:85, L1:21, L2 :37, C: 27, dk:12.038
Water pump bearings are double row bearings and, in contrast to
conventional double row bearings, do not have an inner ring but
raceways machined directly into the surface of the shaft. As a result,
there is more space available for the rolling elements, giving a higher
specific load carrying capacity than that of solutions with conventional
single bearings. Furthermore, it is possible in this type of bearing to
achieve economical combinations of ball and roller rows. In a small
design envelope, this gives a broad range of load carrying capacities.
The use of a common outer ring for two rows of rolling elements prevents
misalignment defects, eliminating the risk of undesirable distortion of
the bearings.
In water pump bearings, the ends of the shaft normally extend beyond
the outer ring on both sides. The length and diameter of these extended
sections are matched to the specific application. This results in
a simple, ready-to-fit bearing unit that is primarily used in water pumps
for road vehicles.
However, they are not restricted to this application.
Due to the advantages described above, they have a wide range of
possible applications.
They can be used, for example, in:
fans
tension pulleys
vane pumps
angle grinders.
Since they are not restricted to use in water pumps, water pump
bearings are also described in English as Integral shaft bearings.
