High Temperature Deep Groove Ball Bearings High temperature bearing has the similar structure with traditional deep groove ball bearing,since the using environment is different,high temperature bearing needs to be forged in more harsh conditions.The forging temperature is higher than normal bearing,which to ensurance the high temperature can be used in special situation.The most important of high temperature bearing is the oil.Same as the material,oil needs to stand in the high temperature conditon. Features of high temperature bearings 1 higher using temperature 2 bigger clearance 3 harsh conditon of oil Specification of high temperature deep groove ball bearing with bigger clearance

Deep groove ball bearings for high temperature applications

SKF deep groove ball bearings for high temperature applications correspond in design to standard single row deep groove ball bearings of the same size. They have no filling slots and can accommodate axial loads in addition to radial loads

The entire surface of the bearing and shields are manganese phosphate coated to enhance adhesion of the lubricant to the metal and improve the running-in properties of the bearing. 

The radial internal clearance is a multiple of C5 to prevent the bearings from seizing, even when they cool rapidly.

Bearing benefits and features

The benefits and features of high temperature deep groove ball bearings include:

1. No need for relubrication 
   All variants,  except open (without shields) VA201 bearings, are lubricated for the life of the bearing with graphite-based high temperature lubricants. Open VA201 bearings require relubrication.
2. Simple replacement 
   The boundary dimensions are the same as those of standard bearings.
3. Operating temperature up to 350 °C (660 °F) 
   The internal radial clearance and the lubricant are optimized for operation at high temperatures.
4. Protection against solid contamination 
   Shields (designation suffix 2Z) protect the bearing.
5. Improved running in 
   The entire bearing surface is manganese phosphate coated.

SKF high temperature bearings and bearing units are designed to deliver increased reliability, reduced complexity and decreased environmental impact in operating temperatures up to 350 °C (660 °F). Because SKF high temperature bearings correspond to the ISO dimensions of grease-lubricated bearings, production efficiencies and cost savings can be realized with a simple change to the SKF bearing solution.

The environmental benefits of SKF high temperature bearings are so significant in many applications that they are included in the "SKF Beyond Zero" product portfolio.

Bearing benefits and features

• Reduced total operating cost 
  The bearings are designed to maintain the radial clearance needed for high temperature operation and so will not seize, even when they cool rapidly, and therefore provide a long service life.
• Virtually maintenance-free operation 
  The bearings are lubricated for life and do not need relubrication. Only variant VA201 without shields requires relubrication.
• Excellent performance under severe conditions:
  • hot conditions
  • dry environments 
  • low rotational speeds
• Reduced environmental impact
• Reduced machine design complexity
