Why rotary table bearings can be applied to CNC rotary table?


Rotary table bearings are typically constructed with two rings, an inner ring and an outer ring, separated by rolling elements such as balls or rollers. The rolling elements allow the inner and outer rings to rotate relative to each other, while also supporting axial and radial loads. The number and size of the rolling elements can vary, depending on the specific application and load requirements.

Rotary tables are mechanical devices used to rotate a workpiece to a precise position, enabling precise machining operations such as drilling, milling, and cutting. Rotary table bearings support the rotating table, ensuring smooth and precise movement.

They are often used in CNC rotary tables because they provide a stable and precise platform for rotational movement. CNC (Computer Numerical Control) rotary tables are used in various machining applications to hold and rotate workpieces for accurate and efficient machining operations. The rotary table bearings enable smooth and accurate rotation of the table, allowing the machining tools to make precise cuts at specific angles.


Rotary table bearings are designed to handle both radial and axial loads, ensuring stability and accuracy during operation. They are typically constructed with high-quality materials, such as hardened steel or ceramic, and feature precision manufacturing techniques to ensure minimal runout and maximum precision.

Additionally, rotary table bearings are often designed with a low profile and compact footprint, which makes them ideal for use in the limited space of CNC machines. They also have a high load-carrying capacity, enabling them to support heavy workpieces and machining operations.
