Deep Groove Ball Bearings

Deep groove ball bearings have full shoulders on both sides of the raceways of the inner and outer rings and can accept radial loads, thrust loads in either direction, or a combination of loads. The full shoulders and the cages used in deep groove bearings make them suitable for the addition of closures. Besides single deep groove bearings with closures, Barden also offers duplex pairs with seals or shields on the outboard faces.

Deep groove bearings are available in many sizes, with a variety of cage types , and this versatility makes them the most widely used type. Hybrid bearings (silicon nitride balls) can be specified to increase bearing stiffness, reduce vibration levels and prolong bearing life.

In summary:

• Cages ... the standard cage is a two-piece steel ribbon type. Most sizes are available with a two-piece riveted phenolic, aluminium-reinforced type. Some sizes are available with a one-piece filled nylon snap-in type. Other options may be available.
• Closures ... Most bearings are available in shielded and sealed versions.  
• Lubricant ... Lubrication can be specified by the customer or recommended by Barden, based on the torque, speed and temperature conditions of the application.
• Loads ... Deep groove ball bearings can accept radial loads, thrust loads in either direction, or combinations of loads (full complement bearings).
• Duplexing ... They can be supplied in matched pairs for duplex DB, DF or DT mounting.
