Angular Contact Ball Bearings

Overview

Angular Contact Ball Bearings

NYZ offers a comprehensive range of angular contact ball bearings, designed to meet the evolving needs of equipment manufacturers across various industries.

The inner and outer ring raceways of angular contact ball bearings are offset relative to the bearing axis, forming an angle known as the contact angle. Common contact angles include 15 degrees, 25 degrees, and 40 degrees. This design allows the bearings to simultaneously handle radial loads and unidirectional axial loads. When the radial load is significant, it generates an axial component, making it common to use angular ball bearings in pairs or in multiple bearing arrangements.

Product List

Single-Row Angular Contact Ball Bearings

Single row ball bearings

Single-row angular contact ball bearings consist of an inner ring, an outer ring, and a set of steel balls. The steel balls are positioned between the raceways of the inner and outer rings and are in angular contact with both raceways. Single-row angular contact bearings are designed to withstand axial loads in one direction only, so they are typically paired with another bearing to handle the reverse axial load in practical applications.

Features:

  • Contact Angle:Non-separable design with different contact angles of 15 degrees, 25 degrees, and 40 degrees. The larger the contact angle, the greater the axial load the bearing can withstand.
  • High Precision:Suitable for high-precision applications requiring accurate positioning and stable operation.
  • High Speed:With low friction, it is suitable for high-speed operation, commonly used in high-speed motors and turbine machinery.
  • Unidirectional Axial Load:Can only withstand unidirectional axial loads, typically requiring pairing with another bearing to handle the reverse axial load.

Single-row angular contact ball bearings are widely used in machine tool spindles, high-speed motors, industrial machinery, automotive transmissions, and aerospace equipment.

Double-Row Angular Contact Ball Bearings

Angular Contact Ball Bearings

Double-row angular contact ball bearings are typically used as fixed-end bearings. They have two sets of steel balls that can simultaneously withstand radial and bidirectional axial loads. Their structure and performance make them suitable for various high-load applications.

Features:

  • Double-Row Design:Composed of two rows of ball bearings, the structure is similar to two single-row angular contact ball bearings arranged back-to-back.
  • High Load Capacity:The double-row design allows the bearing to withstand bidirectional axial loads and is suitable for applications with high radial loads.
  • High Precision and High Speed:Double-row angular contact ball bearings possess high precision and low friction characteristics, making them ideal for high-speed machinery operations.

Double-row angular contact ball bearings are primarily used in the automotive industry, industrial machinery, machine tool equipment, construction equipment, and motors and generators. Their high precision and high-speed characteristics make them an ideal choice for various high-load and high-speed applications.

Bearing Assembly

In order to improve the bearing capacity and stiffness, angular contact ball bearings for machine tool spindles are usually used. Two or more bearings in combination. Commonly used double or multi-link combination methods are shown in the figure. The following performance parameters must be controlled between any two bearings in a matched bearing:

FAQs

Choosing the right angular contact ball bearing requires considering load requirements (radial and axial), operating speed, precision grade, environmental conditions (such as temperature and humidity), and installation space. It is recommended to consult a professional supplier or refer to the equipment manufacturer's recommendations.

The contact angle is the angle between the contact points of the bearing's inner and outer raceways and the rolling elements. A larger contact angle allows the bearing to withstand greater axial loads, but its radial load capacity decreases accordingly. Common contact angles are 15 degrees, 25 degrees, and 40 degrees.

The service life of angular contact ball bearings depends on load, speed, lubrication, installation accuracy, and working environment. With proper maintenance and suitable operating conditions, the bearing's life can reach several years or longer.

Yes, angular contact ball bearings can be used in high-temperature environments, but appropriate high-temperature materials and lubricants must be selected. High temperatures may affect the bearing's life and performance, so regular inspection and maintenance are necessary.

Yes, angular contact ball bearings usually require preload to eliminate axial clearance, increase rigidity, and improve accuracy. The amount of preload should be adjusted according to the specific application requirements and manufacturer's recommendations.
