These are the most common type of ball bearings and are characterized by their deep, uninterrupted raceways. They offer excellent radial and axial load capacities, making them ideal for various applications.
Angular Contact Ball Bearings
Designed to withstand axial and radial loads simultaneously, angular contact ball bearings are commonly used in high-speed applications where angular misalignment is a concern.
Thrust Ball Bearings
As their name suggests, thrust ball bearings are designed to handle primarily axial loads and are used in applications such as clutches and gearboxes.
| Type | Applications | Features |
|---|---|---|
| Deep Groove Ball Bearings | Pumps, motors, power tools | High radial and axial load capacity |
| Angular Contact Ball Bearings | Machine tools, spindles | Axial and radial load capacity, high-speed operation |
| Thrust Ball Bearings | Clutches, gearboxes | High axial load capacity |
Self-Aligning Ball Bearings
These bearings have a spherical outer ring that allows for self-alignment and compensates for shaft misalignment, making them ideal for applications with challenging mounting conditions.
Spherical Plain Bearings
Spherical plain bearings are designed for heavy-duty applications and provide a high degree of angular motion and tilting capabilities.
| Type | Applications | Features |
|---|---|---|
| Self-Aligning Ball Bearings | Conveyors, agricultural equipment | Self-alignment, high radial load capacity |
| Spherical Plain Bearings | Cranes, construction machinery | Angular movement, heavy-duty applications |
