YRTM Rotary Table Bearings

YRTM Rotary table bearings are specialized components designed to support the rotational motion of turntables, indexing tables, and rotary tables used in various industrial applications. Unlike conventional bearings, rotary table bearings are engineered to handle axial, radial, and moment loads simultaneously. This makes them highly suitable for applications that demand precision, stability, and load-bearing capabilities in a compact space.

Introduction

The measurement of angular displacement is a crucial aspect of modern industry. In particular, the machine tool industry has a high demand for the measurement of rotation angles of mechanical parts. It is essential to accurately measure and control the angular displacement.
Currently, grating and magnetic gate encoders are the most commonly used devices for measuring angular displacement. The AMOSIN steel grade measurement system from Austria offers four key advantages: high precision (the highest resolution angle is <2 arc-second), stain resistance, no electrical induction, and high adaptability to circumstances.
The YRT rotary table bearing, in conjunction with this measurement system, offers unparalleled precision, capable of bearing double-direction axial load, radial load, and tilting moment. This makes it an ideal solution for high-precision applications, including high-precision rotary tables in machine tool industries, dividing heads, scientific experiments and measurements, and so on.

Key Types of Rotary Table Bearings

1. Crossed Roller Bearings: In this type, cylindrical rollers are arranged at right angles to each other, providing high rigidity and precision. Crossed roller bearings are compact yet capable of supporting large loads, which makes them ideal for CNC machining centers and precision instruments.

2. Axial-Radial Bearings: These bearings are specifically designed to accommodate axial loads (along the axis of rotation), radial loads (perpendicular to the axis), and tilting moments. Their robust structure is perfect for applications where stability under heavy loads is critical, such as in turntables, robotic arms, and gearboxes.

3. Thrust Ball Bearings: These bearings can handle high axial loads but are less suitable for radial or moment loads. They are often used in applications where primarily axial load support is required, though they are less common in rotary table applications compared to other types.

Features of Rotary Table Bearings

• High Precision: Rotary table bearings offer smooth and consistent rotation, with minimal backlash, which is essential for applications that require accuracy.
• Compact Design: Their ability to handle multiple load types simultaneously allows for a compact bearing structure, reducing equipment footprint.
• Increased Load Capacity: Rotary table bearings are built to manage high loads, making them durable and reliable for heavy-duty applications.
• Long Service Life: With proper lubrication and maintenance, rotary table bearings can endure extended use, providing high reliability in continuous operations.
