Rotary table - Wikipedia
A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical ) axis. Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates that enable regular work positioning at divisions for which indexing …

Ball Bearings Selection Guide: Types, Features, Appliions | …
20/1/2022· Ball bearings are used to provide smooth, low friction motion in rotary appliions. Ball bearings are able to provide high performance and long lifetime in order to transfer the load from the balls to the inner races. The balls have minimal contact with the inner and outer races due to their spherical shape and this allows them to spin smoothly.

Dynamics characteristics of a rotary table motorized spindle with externally pressurized air bearings …
According to type of bearing, the rotary table spindle can be classified into three egories: the spindle with rolling bearing, the spindle with fluid bearing and the spindle with air bearing. The rolling bearing spindle [4-6] is simple in structure, easy for maintenance, but low in rotation accuracy, limited in working life and moderate in loading capacity.
Manual Rotary Table – Sherline Products
