YRTM Series High-Precision Rotating Table Bearings

The YRTM series is a specialized three-row roller bearing that combines a rotary table bearing with an integrated angular measuring system. This design provides both high-precision rotational support and direct position feedback, making it an ideal solution for applications where accurate positioning and reliable motion control are essential.


Typical Applications:

Precision rotary tables and indexing systems

CNC machine tool rotary axes

Measuring and inspection equipment

Medical imaging and radiotherapy devices

Precision positioning stages

YRTM series bearings feature a three-row roller configuration with cylindrical rollers arranged in three separate raceways. Two rows of rollers support axial loads in both directions, while the third row supports radial loads. This arrangement enables the bearing to simultaneously handle axial loads, radial loads, and tilting moments with exceptional rigidity and load capacity.

The defining feature of the YRTM series is its integrated measuring system. An angular encoder is built directly into the bearing, eliminating the need for separate measurement components. The measuring system typically consists of a measuring ring with a precision scale attached to the rotating ring, and a sensor head mounted on the stationary ring. This integration provides several advantages: the measurement system is protected from external contamination, no additional installation space is required, and the risk of alignment errors between the bearing and measurement system is eliminated.
