Double Row Tapered Roller Bearing Series

 Features and Advantages of Double Row Tapered Roller Bearing Series

• High Load Capacity and Rigidity: The double-row design enables these bearings to withstand significant radial loads and bidirectional axial loads simultaneously, offering high rigidity

  . The arrangement of two rows of tapered rollers allows for a wider effective bearing spread, making them ideal for applications with significant overturning moments .

  
  

  
  

• Pre-adjusted Clearance and Simplified Installation: Particularly for bearings with a TDO (Two-Row Double-Outer Race) configuration, the axial clearance or preload is preset at the factory using a spacer between the two inner rings

  . This allows for direct installation and use without the need for additional adjustment, enabling a "ready-to-mount" solution .

  
  

  
  

• Long Service Life and High Reliability: Manufactured from high-quality materials like GCr15 chrome steel or stainless steel, and through precision machining and heat treatment, these bearings achieve extended service life and high reliability

  . Bearings with multi-seal designs can effectively prevent contaminant ingress and lubricant leakage. Their lifespan can be 20%–40% longer than open-style bearings, while lubricant consumption can be reduced by up to 80% .

  
  

  
  

• Multiple Configurations and Options: Beyond the standard TDO and TDI (Two-Row Double-Inner Race) configurations, various options are available to meet diverse application needs

  . These include designs with a large contact angle for applications dominated by axial loads, special sealing arrangements (e.g., TDOS.1 design), and inch series bearings .
