In bearings, the load is transferred from the outer layer to the balls And from
the items, pressure is transferred to the inner layer.The sphericity of the
spheres makes their point of contact with the inner and outer layers very small
As a result, they can move very smoothly, on the other hand Small contact area
if they Excessive pressure on the bullets can cause deformation orIt can be
crushed, in which case roller bearings can be used. Imagine we had cylindrical
wheels in your car like tank wheels In these cases, due to the large contact
that the surface had with this wheel, high friction It was going and as a result
the speed of movement was slowing down. The same thing happened in roller
bearing Falls.
As a result, the bearing speed is faster than the roller bearing.If too much
pressure is applied to the bearings, the bullets inside will be crushed Therefore,
from ball bearings that have small bullets at low pressures Used for high
pressure ball bearings Round boards are used, which are called roller
bearingsSomehow it has a thin roller called a needle bearing.
