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.
