The RTB precision bearings from the company are ready-to-install and compact, comprising combined solutions that consist of two axial bearings and one radial bearing. As the exhibitors explain, their high precision and stiffness is achieved by the large number of rollers in the axial cages, the linear contact of the rolling element, and the precise manufacturing of the bearing. In this way the bearings are said to meet the high demands of accuracy, load capacity and stiffness in machining. Especially for use in torque-driven rotary tables, the axial-radial precision roller bearings from the series are provided with an integrated angle measuring system. This consists of a circular precision scale as a measuring ring, which is fixed on the outer ring of the thrust washer. One or two scanning heads are positioned on the outer ring of the bearing, identify the rotation angle of the grid, and thus generate an output signal for the CNC control unit of the machine tool. Thanks to the inductive measuring method, the bearings are reportedly robust, temperature-stable and easy to mount. Also stressed is the modular design of the system for all specific resolution and precision requirements.
The right precision bearing for every application
The RTB Rotary Table Bearings from Rodriguez are seen by the manufacturers as the ideal solution for rotary tables and swivel heads in machine tools. Components can be quickly and flexibly adapted to specific requirements.
