Ceramic Bearings vs Steel Bearings: An Engineering Analysis - Haini Engineering
11/12/2020· The only real big noticeable difference between the two is the bearing clearance. On ceramic bearings, this is usually a C3 clearance whilst on steel it’s usually CN. The bearing clearance is a measurement given to the small gap between the inner race, outer race and balls. It is required to prevent bearing seizure when it warms up and expands.

Cylindrical roller bearings for main spindles
In machine tool building, they provide radial support for the main spindle. These are single or double row cylindrical roller bearings with a largely tapered bore (taper 1:12) and a removable outer ring, which can thus be mounted separately from the normal bearing package. The inner ring is only removable in the case of series NNU49.
