Inch Taper Roller Bearing Description
It is not possible to imagine any modern machine without the
bearing, the functions of which consist in the significant reducing
of friction between the rotating and stationary machine parts, on
the one hand, and in the ability to carry the defined load, on the
other hand. The seal also takes an important part; it protects the
bearing from the external actions and keeps the bearing lubricated.
Durability and reliability of any machine in a great measure
depends on the right choice and quality of the applied bearings,
seals and lubrication.
For its rather more than 100 years modern history (from the moment
of the beginning of the first mass production in 1883 in Germany,
which became possible due to the innovation of the balls grinding
machine) the rolling bearing remains conservative and at the same
time innovative part of the machines and mechanisms. Constant is
the rolling bearing operation principle (the replacement of sliding
friction by rolling friction) and the rolling bearing main parts
composition (inner and outer rings, rolling elements and cage). At
the same time, following the growing demand in all the industries,
the new bearings constructions permanently appear; the applied
materials, control technology and production engineering are being
improved.
