Compare Sliding Bearing And Rolling Bearing

SLIDING BEARING

• Friction coefficient is great.
• Difficult to achieve Sub – micron positioning.
• Difficult to Estimate life.
• Difficult to Estimate rigidity.
• Their is mechanical play.
• Unsuitable for extremely low and high speed.
• Precision is lost mostly by deteriorated guide surface.
• Poor in taking shock load.
• Do Not Require continuous lubricant supply.

ROLLING BEARING

• Friction coefficient is low.
• Easy to achieve Sub – micron positioning.
• Easy to Estimate life.
• Easy to Estimate rigidity.
• No play because of preload.
• Wide range for use is from low to high speed.
• Long life through simple maintenance.
• Can take shock load.
• Require continuously lubricant supply.
