Bearings is an indispensable component of mechanical equipment. Its main function is to support rotating parts and reduce friction coefficient of mechanical load during transmission. According to different classification standards, bearings can be divided into different types, each type has its own unique characteristics and applications. Here are some common bearing types and characteristics:
1.By Load Direction or contact angle
Radial bearings
Features: Mainly supports radial loads, i.e., forces perpendicular to the axis.
Common types: deep groove ball bearings, cylindrical roller bearings, centring ball bearings, spherical roller bearings, etc.
Uses: Widely used in automobile, machine tools, motor, water pumps and other mechanical equipment requiring radial loads.
Thrust bearings
Features: Mainly supports axial loads, i.e., forces acting along the axis.
Common types: Thrust ball bearings, thrust roller bearings (including spherical thrust roller bearings, cylindrical thrust roller bearings and conical thrust roller bearings).
Uses: Suitable for situations where axial loads is required, such as hydrogenerator, vertical motor, propeller shafts, 2.. By Scroll Type
Ball Bearings
Features: The ball is a rolling element with a low friction coefficient and a high top speed, making it suitable for high-speed rotation.
Common types: deep groove ball bearings, angular contact ball bearings, thrust ball bearings, etc..
Uses: Widely used in mechanical equipment requiring high speed rotation and low friction.
Roller Bearings
Features: roller elements are cylindrical roller, conical roller, spherical roller, etc., high bearing capacity, suitable for heavy load and impact loads.
Common types: Cylindrical roller bearings, conical roller bearings, spherical roller bearings, thrust roller bearings, etc.
Purpose: Suitable for mechanical equipment such as automobile, rolling mill, mine and metallurgy which must withstand heavy load and impact loads.
3. By consistency
Spherical Bearings
Features: Self-alignment to compensate for misalignment caused by deflection or dislocation of the shaft or housing.
Common types: self-aligning ball bearings, self-aligning roller bearings, thrust self-aligning roller bearings, etc. Purpose: It is suitable for paper machinery, speed reducers, rolling railway vehicle axles, etc.
Non-aligning bearings (rigid bearings)
Features: Not aligned, high installation accuracy.
Common types: deep groove ball bearings (misalignment), cylindrical roller bearings (misalignment), etc.
Purpose: Suitable for high accuracy of installation and shaft alignment.
IV. INTRODUCTION By Rolling Element Row
Single-row bearings
Features: contains only one line of scrolling elements, simple structure, suitable for one-way loading.
Common types: singlerow deep groove ball bearings, single row angular contact ball bearings, single row cylindrical roller bearings, etc.
Uses: Widely used in all kinds of mechanical equipment which must be loaded one-way.
Double row bearings
Features: Contains two rolling elements, can bear load in both directions, has a high bearing capacity.
Common types: double-row angular contact ball bearings, double-row cylindrical roller bearings, etc..
Usage: Suitable for situations requiring bidirectional loads, such as oil pumps, rotz blower, air compressors, etc..
Multi-row bearings
Features: These bearings have three or more rows of rolling elements with superiorbearing capacity and are suitable for heavy loads.
Common types include four-row tapered roller bearings.
Uses: Mainly used in rolling mills, mining machinery and other equipment requiring heavy load.
