Product Description

 

YRT Series Bearings - High - Precision Rotary Table Bearings

Product Overview

YRT series bearings, also known as rotary table bearings, are axial and radial combined cylindrical roller bearings. They are composed of two thrust needle roller bearings and a radial cylindrical roller bearing, featuring a combination of axial and radial pre - load. These bearings are designed to meet the high - precision requirements of various industrial applications, offering reliable performance and long - term durability.

Key Features

High - Precision Design

• The unique internal structure of YRT series bearings ensures high - precision operation. With a combination of two rows of axial rollers providing stable axial bearing capacity and one row of radial rollers enabling the bearing to withstand radial force and overturning moment, they are suitable for applications where precision is crucial, such as in precision machine tools and inspection instruments.

• The bearing's high - precision manufacturing process allows for tight tolerances, contributing to smooth rotation and accurate positioning.

Durable Material

• Made from high - quality bearing steel, YRT series bearings offer excellent wear resistance and fatigue strength. The material can withstand harsh operating conditions, including high loads and high - speed rotations, ensuring a long service life.

Easy Installation and Transportation

• To facilitate transportation and installation, the inner and outer rings of YRT series bearings are equipped with screw holes. Additionally, two or three symmetrical screws are fastened to the two rings to prevent rollers and rings from colliding during transportation, which could affect bearing accuracy. The entire set of bearings is pre - loaded at the factory, eliminating the need for on - site clearance adjustment during installation.

Applications

YRT series bearings find wide applications in multiple industries:

• Precision Machine Tools: They are used in the rotation parts of precision machine tools, ensuring smooth and accurate cutting and machining operations.

• CNC Rotary Tables: Provide reliable support and precise rotation for CNC rotary tables, which are essential for multi - axis machining.

• Inspection Instruments: Enable accurate rotation and positioning in inspection instruments, helping to achieve high - precision measurement results.

• Medical Equipment: Used in medical devices where precision and reliability are of utmost importance, such as in some surgical robots and diagnostic equipment.

• Indexing Plates of Other Precision Machines: Ensure accurate indexing and rotation in various precision machinery, improving overall machine performance.

Product Structure

Thrust / radial cylindrical roller bearings in the YRT series are composed of two thrust roller bearings and one radial cylindrical roller bearing. This design allows them to withstand radial loads, bidirectional axial loads, and overturning moments with negative clearance. Some models, such as the YRTS series, have a special internal structure design that enables higher limit speeds.
