The Thin section Bearings
Thin section bearings have small cross-sections regarding their diameter.
Thin section bearings are made to save space, lower the weight on the design and
reduce rubbing. Thin and extra thin section bearings are available in inch or
metric different sizes and in chrome or stainless. These ranges are additionally
available with cages with regard to high-speed applications, and with extended
inner rings. Thin section bearings are produced to industry standard types. The
bearing widths and distance from bore to help outside diameter remains constant
whatever the change in bore diameter.
Standard bearing installation
practices may be used in conjunction with thin section bearings. Both the inner
and outer rings can merely be pushed into position, on the housing together with
shaft respectively. Installation should only be performed in the clean,
contamination free area as thin section bearings lack seals and grit or other
contaminants could easily get into the bearings and disrupt their
performance.
Due to the large diameters and thin sections of these bearings, it is important to address measurement together with inspection. To
accurately measure the bore diameter and also the outside diameter of a lot of
these thin section bearings special procedures has to be followed. Special gages
allow three to five measurements around the circumference of the diameter to be
applied. These measurements are then averaged to determine the true measurement
of the bearing inside unmounted free state. This process allows for inherent
out-of-roundness.
Load ratings and bearing dimensional data may be
compiled from industry standard data and ABMA and ANSI information and formulas
to your thin section bearing app. To calculate the theoretical L10 lifetime in
hours while which include application dynamic loading, application speeds (rpm)
and defined catalog load capacities (C) operate the following industry standard
solution.
Using the catalog load capacities where:
L10 = 06, 667/S
* (C/P)3
P = application applied download
C = dynamic rating in
catalog
S = use speed in RPM
L10 = theoretical showing L10 life in
hours
Thin section ball bearings usually are used in applications using
space, weight, and insert constraints. Some typical functions for standard
thin-section ball bearings include machine equipment, packaging and textile
equipment, satellite systems, medical equipment, radar and material dealing with
equipment, satellite equipment, aerospace, optical and manufacturing
equipment.
