Thin Section Bearings
There are three types of thin-section bearings: deep
groove bearings, four-point contact bearings, and angular contact bearings.
Compared with standard-section ball bearings all three bearing types offer
advantages in reduced space requirements and low cost. These bearings are
used primarily where shaft location is the major requirement.
structural components these thin-section bearings behave
differently to standard bearings because their bearing rings are
quite flexible. Under load the rings follow the imperfections of
shaft and bores, consequently, it is essential that these
components be geometrically accurate.
contact bearings support thrust loads in either direction these are much
more effective in resisting moment loads than the deep-groove design
Two other bearing
designs use an axial split in the outer ring to increase ball complement and
radial capacity without sacrificing thrust capacity. One is a
full-complement design, the other uses alternating full-size balls and
spacer balls. The latter type also has high shoulders on the outer ring to
provide integral shields for grease lubrication. Both types of bearings are
held together with wire bands after assembly.
bearings are used widely in Aircraft, Aerospace, Textile printer, Medical
devices, Radar Communication, Astronomy instrumentation and Industrial
robotics etc. because their characteristics such as small space, light
weight and low friction.
