Introduction
Bearings play a pivotal role in mechanical design, facilitating reduced friction and support for rotating parts. Understanding the specifications of bearings is crucial for selecting the most suitable bearing for a particular application.
Types of Bearings
Deep Groove Ball Bearings
- Usage: Widely used in various machinery, especially in motors and pumps.
- Advantages: High load-bearing capacity, good wear resistance.
- Disadvantages: Limited axial load capacity.
Tapered Roller Bearings
- Usage: Primarily for bearing combined (radial and axial) loads.
- Advantages: Good load capacity, suitable for heavy-load applications.
- Disadvantages: Relatively higher cost.
