High-speed ball bearings are a rolling system made of rings and ball-shaped rolling elements. The bearing working angle is in the range of 12-30 degrees (oblique variant). The working angle translates into, among others bearing capacity, stiffness and rotation. High-speed ball bearings are characterized by durability, precision of rotation, efficiency, and work at very high speeds. They are used in processing plants, in devices such as drills, grinders, milling machines and lathes.
High-speed bearings (spindle bearings) are mainly used in the machining process. Increased rotational speed, low thermal level, good stiffness, high rotation accuracy and durability are the main requirements that must be met.
The most important advantages of precision bearings are:
Reduced maintenance costs due to reliability and durability.
Reduction in machining times due to increased speed and optimal load capacity.
High quality parameters, such as: limited heating, guaranteed accuracy of initial clamping, high rotation accuracy, stiffness.
