3. Feature: There are two series (718 series and 719 series) of CHG light precision angular contact ball bearings; they have the same inside diameter and the outside diameter and width are increased successively.
The single-row angular contact ball bearing can bear a radial load and an axial load in one direction, and it can bear a single axial load in one direction; under the radial load, its axial component load will be caused. Therefore, the single row angular contact ball bearing should be matched with the other bearing to bear the axial load in the opposite direction. So, 2, 3, 4 or even 5 angular contact ball bearings are usually matched together for use, and the angular contact ball bearing has a high limiting speeds.
The contact angles of CHG light series precision angular contact ball bearings are 15° (Code C), 25° (Code AC) and 40° (Code B); for the angular contact ball bearings, the contact angle is greater, the axial load capacity is larger, but the bearing limiting speeds is lower. Therefore, the bearing with the contact angle of 15° is used on the shaft with high speeds and small axial load; on the contrary, the angular contact ball bearings with the contact angle of 25° or 40° should be used.
CHG precision angular contact ball bearings can be divided into 3 series of high-speed angular contact bearings (standard series), ultra high-speed angular contact ceramic ball bearings, and high speed sealed angular contact ball bearings.
4. CHG can also offer angular contact hybrid ceramic ball bearings with wide applications for high-speed precision machine tool spindle and other high-speed precision machinery spindle, in which, the inner and outer rings should be made of high quality bearing steel material, and the rolling elements should be made of silicon nitride ceramics.

What is a Precision Angular Contact Ball Bearing?

A Precision Angular Contact Ball Bearing is ideal for industries with stringent performance requirements because it is designed to handle high-speed and high-precision applications. An angular contact ball bearing, in contrast to standard ball bearings, is made to carry axial loads only in one direction. They are typically used in pairs or sets to carry both radial and axial loads. Because of their angular contact design, they are able to precisely control the movement of the shaft, reducing friction and increasing reliability.

FAQ

Q1. What is the difference between angular contact ball bearings and radial ball bearings?
Angular contact ball bearings are designed to handle axial loads in one direction and are often used in pairs to support both radial and axial loads. Radial ball bearings, on the other hand, are primarily designed to handle radial loads.

Q2. Can it be used in high-temperature environments?
Yes, it can be designed with special materials and lubricants to withstand high-temperature environments. Consult with us for specific requirements.

Q3. How often should I replace Precision Angular Contact Ball Bearings?
Replacement frequency depends on the application and operating conditions. Regular inspection and maintenance can help determine when a replacement is necessary.
