Does internal clearance effect the bearing precision? Internal clearance is the amount of internal free space between the rolling elements and the raceways of a bearing. C1 is a range less than C2. C2 is a range less than normal. C3 is a range greater than normal, C4 is a range greater than C3 and C5 is a range greater than C4. Precision is a range of tolerance on bearing dimensions. Ultimately, clearance does not affect tolerance and tolerance does not affect clearance. TOP Is it safe to use a C3 fit in place of a standard fit? C3 is typically not referred to as a fit; it is the internal clearance in the bearing as defined above. A bearing fit is how tight or loose the shaft and housing hold the bearing in place. When either of the rings of a bearing is tight fitted to its mating component i. A rotating bearing also produces heat due to material stress and through friction from rolling and sliding contact, lubricant shear, and seal contact. The bearing housing is usually stationary and is therefore better able to conduct heat away from the outer ring of the bearing.

TOP Is it safe to use a C3 fit in place of a standard fit? C3 is typically not referred to as a fit; it is the internal clearance in the bearing as defined above.

A bearing fit is how tight or loose the shaft and housing hold the bearing in place. When either of the rings of a bearing is tight fitted to its mating component i. A rotating bearing also produces heat due to material stress and through friction from rolling and sliding contact, lubricant shear, and seal contact.

The bearing housing is usually stationary and is therefore better able to conduct heat away from the outer ring of the bearing. This results in greater thermal expansion of the inner ring and thus reduces the clearance in the bearing.

Ball and Roller Bearings

If the shaft is being heated or if the housing is being cooled, the temperature difference will be even greater. Selection of the proper initial bearing internal clearance must take all the foregoing factors into consideration.
