Combination Angular Contact Ball Bearings

• Normally Single Row Angular Contact Ball Bearings are used as a combination of two or more bearings.
• Three types of combinations are available:
  1. DB, back to back
  2. DF, face to face
  3. DT, tandem
• Clearance of matched set is adjusted before shipment; care should be taken to prevent mixing of parts from other sets.
• High precision paired combination Angular Contact Ball Bearings (JIS/ISO class 5 or higher) are used for applications such as machine tool spindles and are usually preloaded.
