This training video by ICKIFI introduces bearings, covering a wide range from tiny high-precision bearings for cameras to large spherical roller bearings for harsh environments. It discusses two basic families of bearings based on their rolling elements.
Introduction to Bearings
- Bearings come in two main types: ball bearings and roller bearings.
- Ball bearings have small elliptical contact areas with the raceway, offering low friction and smooth operation but limited load capacity.
- Roller bearings have broader contact areas, suitable for heavy and impact loads.
Types of Ball Bearings
- Deep groove ball bearing is versatile, popular, supporting radial and axial loads for various applications like electric motors and appliances.
- Double row angular contact ball bearing allows dynamic misalignment, ideal for situations with misaligned housing or shaft deflection.
Types of Roller Bearings
- Cylindrical roller bearing supports high radial loads precisely; some variants allow axial movement between rings for precise shaft expansion applications.
- Tapered roller bearing is robust, handling radial and axial loads in one direction; used similarly to double row angular contact ball bearing.

The discussion continues on various types of roller bearings such as spherical roller bearing, CARB bearing, and considerations like mounting, lubrication, and maintenance.
More on Roller Bearings
- Spherical roller bearing can withstand heavy radial and axial loads in any direction while tolerating dynamic/static misalignments; widely used in industrial plants.
- CARB bearing by SKF offers unique properties with elongated spherical rollers allowing dynamic misalignment tolerance along with high radial load capacity.
Bearing Maintenance Considerations
- Proper mounting of bearings is crucial to prevent sliding under load; internal clearances must be set right to avoid preload issues for satisfactory performance.
