In this video, we will learn about 5 digits bearing number nomenclature. We have taken here the example of Taper Roller bearing 32205 wherein i have discussed 5 digits in details separately. Each digit has different meaning like first digit indicates bearing type, 2nd digit indicates width series, 3rd for outer diameter and 4th & 5th digit indicates bore or inner diameter of bearing. Now we brief here the definition of Tapered Roller Bearings first, Taper roller bearings have tapered raceways in the inner and outer rings with conical rollers arranged between them.
Due to the contact angle, tapered roller bearings can absorb high radial and axial forces in one direction.
Tapered roller bearings are often combined in pairs to support axial forces in both directions.
Bearing is a machine element which makes relative motion and is used to reduce the friction between moving parts.
Bearing employs to guide, support, bear & restrain moving the element.This is a stationary member & it carries the following loads
Radial loads
Axial loads
Bearing are classified into two main types
(1.) Anti friction Bearings / Rolling Surface Bearings
which are further divided into as follows
(1.a) Ball Bearings like
thrust ball bearings
angular contact ball bearings
self allingning ball bearings
deepgrooves ball bearings
(1.b) Roller bearings like
cylinderical roller bearings
spherical roller bearings
tapperd roller bearings
needle roller bearings
(2.) Friction bearings / Slidingo Surface Bearings like
Journal bearings
Plain Bearings
Bush bearings
Brass Bearings
