Different Types of Rotary Table Bearing

Rotary table bearing is a type of bearing, which is used in rotary tables. These bearings are designed to rotate the shaft and radial rollers. This makes it easy to install, and it helps to increase the accuracy of the machine. However, it is important to understand that different types of rotary table bearings have different features and characteristics. Some of these features include low speed and compact structure.

YRT Rotary Table Bearings are commonly used in the manufacturing industry. They provide a high level of accuracy, and they can withstand radial and axial loads. In addition, YRT bearings can be adapted to meet a wide range of requirements. For example, the YRTS series is typically used in high performance machines and has an inside diameter of up to 460mm.

The YRT80 series includes a radial and axial combined cylindrical roller bearing. Its high accuracy and radial load capacity makes it an ideal choice for rotary tables. Another product that is widely used is the ZKLDF series. It offers similar performance with improved rating life. YRTs and ZKXDF bearings are available in a variety of configurations.

YRTSM rotary table bearings enable close loop control of the rotary table, which reduces friction. This results in negligible reversal error, which frees up drive torque and improves machining accuracy. YRTSM bearings have a higher rigidity than open loop bearings, which can significantly improve the precision of the rotary table.

YRTC series bearings also offer increased operating speeds and reduced friction. They are suitable for single workpiece clamping operations and multi-axis simultaneous machining applications. Their small size and ease of assembly allow for more compact rotary table supports.

Compared to other bearings, YRTC bearings are also available with a specialized design that allows the bearings to achieve greater rigidity and operational reliability. Moreover, the YRTSM rotary table bearings can handle a variety of load conditions and minimize reversal errors, which increases the accuracy of the rotary table.

Other bearings are able to provide a very smooth motion without a considerable amount of wobble. However, they do not have the same long service life as air-bearing or oil-hydrostatic rotary tables. Mechanical-bearing rotary tables are a good option for most applications, although they do not provide the same level of accuracy as air-bearing and oil-hydrostatic rotary tables. Nevertheless, they can be useful for applications that require extreme stiffness.

A-688 direct drive rotary table with air bearings is a highly accurate and reliable rotary table that is clean room compatible. Its angular resolution is better than 175nm. Also, it can be used in any orientation.

Cross roller bearings are ideal for rotary tables, because they are capable of receiving loads in all directions. They are easy to install and can be adapted to different preloads. Because they can be installed easily, they can be used in a variety of applications, such as IC manufacturing machines. Furthermore, they have a high static load capacity. Besides, they are simple to maintain.
