Bearing is a
rotating device that is used to reduce friction while allowing linear and
rotational movements. Resembling small wheels, bearings literally allow a
machine to roll over it for smooth function. The friction is reduced between
the bearing and the surface which is rolled over it. The uses of bearings,
while reducing friction enhance speed and efficiency.
Bearings are
basically made of small ball that have smooth surfaces both on internal and
external front. The bearings themselves carry the load of the weight. It is the
load of the surface which rotates the bearings. The loading on the bearings are
not the same and the loading is of two types, radial and thrust.
In radial
load, like that of a pulley, the weight on the bearings causes it to rotate and
roll. In thrust load, the stress on bearings is on entirely different way. Some bearings are designed to carry both
radial and thrust load. The tries of car are both used to carry radial and
thrust load. Bearings can be divided into different kinds depending on the type
of load they are made to carry and the amount of that load.
Ball bearings
are very common type of bearings. They can handle both type of thrust and radial
load but the amount of the load is very small. They can be found in wide
applications such as roller blades and hard drives. These bearings can break if
more than permitted load is put on them.
Roller
bearings NSK Ball
bearings in Delhi are made to
carry large amount of load. This bearing is in form of a cylinder, where the
load is distributed over a large area, this design permits the bearing to take
large load. This design is meant only for radial load not for thrust loads. In
application where space is constraint, the needle bearings are used. The needle
bearings are used with small diameters cylinder
Ball thrust
bearings are made to handle the thrust load in low speed low load applications.
Ball thrust bearings are used in bar stool s to support the weight of the seat.
Roller thrust
bearings SKF Bearing
dealer in Delhi are used to
handle the large thrust load. They are used in cars, where they handle the
handle the helical gears. . Tapered roller bearings are used to handle both
radial and thrust loads. They are used
in car hubs because car wheels have to take large amount in both radial and
thrust variety. Some bearings are made for specific uses. The magnetic bearings
and giant roller bearings are the example of these types of bearings. Magnetic
bearings are used in high speed devices because they have no moving parts and
provide stability for devices that move very fast. Giant rollers bearings are
use do move large structure like buildings and large structural components. They are also used at shipyards to move the
ships for repair works.
