Hybrid spindle bearings combine raceways made of rolling bearing steel with balls made of silicon nitride ceramics. This combination of materials combines the high load capacity of steel with the low density and excellent wear resistance of ceramic rolling elements. The result is bearings with significantly reduced friction, minimal heat generation and increased speed limits.
Hybrid spindle bearings impress with their high running accuracy, thermal stability and energy efficiency. They are the first choice for demanding precision spindles, machine tools and drives where reliability, smooth running and durability are top priorities.
