overview
KG Self-Aligning Ball Bearings
KG Self-Aligning Ball Bearings are engineered to deliver exceptional performance in applications where shaft misalignment or deflection may occur. These bearings are designed to accommodate angular misalignment while maintaining smooth and efficient operation, ensuring reliability across various industrial applications.
KG Self-Aligning Ball Bearings consist of two rows of balls and a common sphered raceway in the outer ring. This design allows the bearings to self-align, compensating for shaft misalignment and minimizing friction.
Key Features
- Self-Alignment Capability: Automatically compensates for shaft misalignment and deflection.​
- Low Friction: Optimized for smooth operation and reduced heat generation.​
- High-Speed Performance: Suitable for applications requiring consistent high-speed operation.​
- Durability: Manufactured using high-quality materials for extended bearing life.​
- Versatile Design: Available in open and sealed variants for different environmental conditions.
Application
- Agricultural machinery
- Textile machinery
- Conveyors and material handling equipment
- Paper mills
Fans and blowers
FAQ's
What are radial loads and axial loads?
Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads
How do deep groove ball bearings (DGBBs) differ from single-row angular contact ball bearings?
While DGBBs can handle axial loads in both directions, single-row angular contact ball bearings can only receive axial load in one direction.
What are the differences between open, sealed, and shielded deep groove ball bearings?
Seals and shields offer additional protection for bearing components and help to improve and maintain lubrication. In terms of sealing performance, sealed bearings rank best, followed by shielded bearings, then finally open bearings.
NSK uses supplementary designations D, DU, DW, and V (DD, DDU, DDW, VV) for sealed bearings and Z (ZZ) for shielded bearings. No supplementary designations are listed for open bearings.
