An indexing table is a rotating platform or rotary table used in automation technology and other areas to precisely position and index workpieces or tools. Rotary indexing tables enable the repeatability of positions and allow different machining steps or assembly operations to be performed at different stations.
Roller bearings are often used in rotary indexing tables to support rotation and ensure low-friction movement. Roller bearings are bearings based on rollers or balls that roll between the inner and outer rings to enable low-friction rotary motion.
Various types of rolling bearings are used in rotary indexing tables depending on the specific requirements, including
1. ball bearings: ball bearings use balls as rolling elements that run in an annular groove between the inner and outer rings. They offer high load carrying capacity and precision at high speeds. Ball bearings are often used in rotary indexing tables to enable fast and precise indexing.
2. roller bearings: Roller bearings use cylindrical or conical rollers as rolling elements. They offer a higher load capacity than ball bearings and are well suited for applications with heavy loads. Roller bearings are often used in large rotary indexing tables or in applications with high loads.
3. tapered roller bearings: Tapered roller bearings are a special type of roller bearing in which the rollers are conical in shape. They offer high axial and radial load carrying capacity and are often used in rotary indexing tables with high loads and high torques.
The selection of the right rolling bearing for a rotary indexing table depends on various factors, such as load capacity, accuracy, rotational speed, rigidity and service life. It is important to consider the specific requirements of the application and select suitable bearings with appropriate dimensions and characteristics to ensure reliable and low-friction rotary motion of the rotary indexing table.
