Description
Material
Ceramic bearings ZrO2.
Bearing cage PTFE.
Bearing cage PTFE.
Version
Natural, white.
Note
Zirconia (ZrO2) is a cost-effective alternative to Si3N4. It also has the advantage that the thermal expansion is similar to that of steel, which means that a shrink fit is not required as expansion differences between the bearing housing and a steel shaft do not occur.
Safety
Reacts with concentrated hydrochloric acid, nitric acid and sulphuric acid.
