Different types of machinery, bearing operating conditions will be
different, and their functional requirements are not the same, but
usually speaking, the use of a bearing on the shaft of not less than
two.
Also,
in order to facilitate axial positioning, most of the bearings are used
as fixed-end bearings and others as free-end bearings. The following table lists the selection of fixed-end and free-end bearing structures. Fixed-end
bearings For the axial positioning and fixation of bearings, bearings
that can accept both radial and axial loads are accepted to accept
two-way axial loads. It is also necessary to consider the corresponding
strength based on the magnitude of the axial load. Deep
Groove Ball Bearings Combination Angular Touch Ball Bearings Double Row
Angular Contact Ball Bearings Self-aligning Ball Bearings Ribbed
Cylindrical Roller Bearings (NUP Type, NH Type) Double Row Roller
Bearings Self-aligning Roller Bearings Self-allocating Bearings for
Avoidance The elasticity of the shaft resulting from the temperature change during operation, and the axial orientation of the bearing. Should choose to only accept radial loads and the inner ring and the outer ring can be separate from the bearing.
When
using non-aligned bearings, the gap between the outer ring and the
outer shell is usually used for cooperation so that the shaft can be
axially avoided together with the bearing when it is elastic. It
is used to avoid the elasticity of the shaft caused by the temperature
change during operation and to adjust the axial orientation of the
bearing.
