| Depending upon the nature of contact
between the working:-Based on this criteria they may be
categorized into two general classes, each with two
sub-types. |
| |
|
Plain (Friction bearings, Sliding Contact Bearings)
|
| The primary motion between the bearing
and the moving element is the sliding one: |
- Cylindrical bearing: can be made from
a cast, solid bronze material. Cylindrical bearings can
be available as plain bearings, cored bars or solid bars
in the market.
- Thrust bearing: can be made from
porous bronze, oil impregnated type of bearing material.
Thrust bearings can be available as plain bearings (also
known as sleeve bearings), flanged bearings,
thrust-bearings, cored bars, solid bars and plate stock.
- Linear sliding bearings made form
cast iron or brass.
|
|
Anti-Friction Bearings (Rolling
Contact Bearings): |
| In these bearings, the contact between
the bearing element is rolling instead of sliding as in
plain bearings. Since the rolling friction is very less as
compared to the sliding friction, such bearings are also
known as “ Anti-friction Bearings”. |
| |
| The rolling element bearings are
classified into: |
- Ball bearing:- In these bearings, the
rolling element is a spherical ball.
- Roller bearings:- In these bearings,
the rolling element is a roller, which might be
cylindrical, conical, spherical, or concave.
|
| Depending upon the load to be carried,
the rolling contact bearings may be categorized as: |
- Radial Bearings:- In radial contact
bearings, the load is primarily radial with only low
magnitude thrust load.
- Thrust Bearings:-These bearings
handle loads which are primarily thrust.
- Angular Contact Bearings:-These
bearings are used where the loads are combined radial
and high thrust, and where accurate shaft location is
required.
