Self-Aligning Spherical Roller Bearings
overview
Self-Aligning Spherical Roller Bearings
KG Self-Aligning Spherical Roller Bearings feature two rows of symmetrical rollers and a common sphered raceway in the outer ring. This unique design allows the bearings to self-align and maintain performance even in cases of shaft deflection and misalignment, accommodating heavy radial and axial loads. These bearings are designed to deliver superior load-carrying capacity, exceptional durability, and reliable performance under the most demanding conditions.
Features
- Self-Alignment Capability: Automatically compensates for shaft misalignment or housing deflection.
- High Radial and Moderate Axial Load Capacity: Designed to handle heavy radial loads and moderate axial loads in both directions.
- Adjustable Clearance: Axial clearance can be adjusted during mounting, allowing precise control over performance and preload.
- Separable Components:Â The inner (cone) and outer (cup) rings can be mounted separately for ease of assembly and inspection.
- Long Service Life:Â Manufactured with high-quality steel and precision engineering for durability and reliability under extreme conditions.
Applications
- Mining and Quarry Equipment
- Steel and Paper Mills
- Cement Processing Plants
- Pulp and Paper Machinery
- Construction Equipment
- Heavy-Duty Fans and Blowers
- Gearboxes and Conveyors
- Wind Turbines and Marine Drives

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.
