Application:
The motorized spindle is mainly used in high-end precision machining.
For example,
"3C wearing parts machining, workpiece finishing, aerospace propeller cutting, engine cylinder machining, car chassis machining, transmission joint grinding, etc. The commonality of these applications is the need for rapid and flexible capabilities during processing."
Features:
Due to their very narrow tolerances, the Machine tool spindle bearing are particularly suitable for applications with the highest guidance accuracy requirement, such as bearing arrangements for main spindles in machine tools.
Tolerance classes for ball bearings were defined by a committee within the ABMA known as the "Annular Bearings Engineers Committee" (ABEC). These tolerances are commonly referred to as ABEC rating or grade.
The higher the classification number, the tighter the tolerances become, resulting in higher precision of the Machine tool spindle bearing.
