Rotary table bearings are an essential component in a variety of machinery and equipment, especially in precision applications. One notable type is the YRT Rotary Table Bearing, known for its high load capacity, precision, and rigidity. This article will delve into the function, application, and design of YRT Rotary Table Bearings.

Rotary Table Bearings including YRT, YRTC standard series, YRTS high-speed series, YRTM with Integrated angle measuring system series And ZKLDF thrust angular contact ball series, all have high rotation accuracy, can withstand radial load, two-way axial load and overturning Torque, suitable for high-precision eyeable joint load occasion, such as rotary table, indexing head, direct-drive motor, rotary milling head, measuring equipment.

 

What are YRT Rotary Table Bearings?

YRT Rotary Table Bearings are part of a category of bearings known as axial radial cylindrical roller bearings. They are specifically designed to handle combined axial and radial loads, and to accommodate tilting moments. Thanks to their design and structure, these bearings are highly suited for high-precision applications where the alignment of the shaft and housing is critical.

YRT Rotary Table Bearing consist of a thrust/centripetal seat ring, a thrust/centripetal shaft ring, a thrust Washer, two needle roller cage assemblies and a set of centripetal cylindrical rollers. The seat ring and the shaft ring have uniformly distributed screw holes for installation. This type of bearing has high axial and radial bearing capacity. The thrust-centripetal composite structure can bear the axial load, the radial load and the overturning moment. The bearings are all equipped with mounting holes, which can be fixed directly by bolts. The bearings are pre-loaded when leaving the factory, and the installation does not need to adjust the clearance YRT Rotary Table bearing series is suitable for low speed, short running cycle crack, high rigidity and precision, such as rotary table, indexing head and so on.

Key Features of YRT Rotary Table Bearings

High Load Capacity: YRT Rotary Table Bearings have a high load capacity in both axial and radial directions. This makes them ideal for use in machinery and equipment that undergo substantial load during operation.

Precision and Rigidity: These bearings are designed with high precision and rigidity in mind. They provide excellent stability under high rotational speeds, which is crucial in precision applications.

Compact Design: Despite their high load capacity and precision, YRT Rotary Table Bearings have a compact design, making them suitable for applications where space is a premium.

Accommodation of Tilting Moments: YRT Rotary Table Bearings can handle tilting moments, which are common in complex machinery and equipment.

YRTS Rotary Table Bearings

Design of YRT Rotary Table Bearings

The design of YRT Rotary Table Bearings is centered around its ability to handle axial, radial, and tilting moment loads. They typically consist of a radial bearing, a thrust bearing, and a set of cage assemblies.

The radial bearing is designed to handle radial loads and limit radial displacement of the shaft relative to the housing.
The thrust bearing is designed to handle axial loads and limit axial displacement.
The cage assemblies hold and separate the rolling elements, reducing friction and wear, and contributing to the bearing’s overall precision and performance.
From a materials perspective, these bearings are usually made from high-quality bearing steel, which offers excellent hardness, wear resistance, and fatigue life.
