Radial Precision Bearings
Spindle and main shaft bearings are specialized bearings used in applications requiring high precision and speed. These bearings are designed to ensure the accurate rotation of the spindle in equipment such as machine tools, CNC machines, and machining centers. Spindle bearings provide low friction, high rigidity, and temperature control, ensuring stable operation even at high speeds. Main shaft bearings, on the other hand, support heavy loads and ensure durability. Typically, these bearings are designed as angular contact ball bearings, cylindrical roller bearings, or hybrid ceramic bearings, and they are available in high precision classes. Spindle and main shaft bearings play a critical role in manufacturing processes, enhancing processing quality by meeting the demands for high speed, precision, and durability. Due to their characteristics, they are preferred solutions for meeting the precision machining requirements in the industry.Unit of Measurement
