Overview of Angular Contact Ball Bearings
Sometimes referred to as “spindle bearings,” angular contact bearings are used in machinery that requires high accuracy and durability.Angular contact bearings have a much higher speed rating than radial bearings because of the nonstop contact of the balls to both rings.Angular contact bearings can carry both radial and axial loads. The weight of the load is transferred from one ring to the other, through the balls, along a specific contact angle.

Advantages of Angular Contact Ball Bearings
Increased durability
These bearings are designed to withstand high loads. The balls in the bearing are separated by a metal cage, which helps to evenly distribute the load and prevent the balls from coming into contact with each other. This results in a more durable bearing that can withstand higher loads for longer periods.
Reduced friction
These types of bearings have lower friction than other types of bearings. This is due to the way the balls are separated by the metal cage. The cage helps to reduce the amount of contact between the balls and the bearing surface, which reduces friction.
Improved efficiency
These bearings are more efficient than other types of bearings because they have less friction. This means that they require less energy to operate, which can lead to savings in both energy and operating costs.
Requires Less Axial Space
In such arrangements where there is limited axial space, it can fit in well without using multiple bearings.
Designed for High Rigidity
Best to be used in those use cases where High Rigidity and Precision are the utmost priority.
Types of Angular Contact Ball Bearings
Single-row angular contact ball bearings
Single-row angular contact ball bearings are bearings that are capable of accommodating axial load only. This bearing is usually connected or adjusted with a second bearing. Their rings have a high and low shoulder, which cannot be separated.
Double-row angular contact ball bearings
Corresponding to the single-row ball bearings are double-row bearings, which are basically two single-row ones placed with back-to-back configuration.
Four-point contact ball bearings
These four-point contact ball bearings are made to support the axial loads from both directions. These bearings are usually separable, meaning the outer ring with the ball and the cage can be installed or mounted, separated from the inner ring raceways.
Application of Angular Contact Ball Bearings
Machine Tool Spindles
Angular contact ball bearings are widely used in the spindles of machine tools, where they provide the precision and rigidity needed for high-speed and high-accuracy machining operations. They can accommodate high radial loads, high axial loads in one direction, and combined loads.
01
Automotive Applications
In the automotive industry, angular contact ball bearings are used in gearboxes, pumps, and clutches. They help manage the loads generated by high-speed rotation and directional changes, providing durability and reliability under various driving conditions.
02
Electric Motors
These bearings are commonly used in electric motors and generators where both radial and axial loads need to be supported, particularly in applications requiring high rotational speed and precision.
03
Aerospace
In the aerospace sector, angular contact ball bearings are used in jet engines and other components where high performance, precision, and reliability are critical. They can withstand the complex load combinations experienced in flight.
04
Agricultural Equipment
Angular contact ball bearings are used in agricultural machinery like harvesters and tractors. They are ideal for withstanding heavy loads and harsh environments.
05
Parts & Material of an Angular Contact Bearing
There are three main parts that make up the angular contact bearing they are the rings, cage, and ball material.
Bearing Rings (a.k.a. Bearing Races or Bearing Raceway)
Our bearing rings are manufactured with 52100 vacuum degassed chrome steel (100Cr6) and are heat stabilized for temperatures up to 302°F (150°C).
An additional heat treatment can be performed for working temperatures up to 572°F (300°C). For working temperatures above 572°F (300°C), we manufacture the rings with high temperature tool steel.
Bearing Cage
A standard TA cage made from phenolic resin with fine mesh cotton webbing allows operating temperatures of 248°F (120°C).
Ball Bearing Material
Here are the two common options for ball material:
52100 vacuum degassed chrome steel (100Cr6), commonly referred to as bearing steel
Ceramic, Silicon Nitride (Si3N4) which can operate at faster speeds and has lower rolling friction. Read all about the benefits of ceramic ball material.

Installation Require for Angular Contact Ball Bearings
During installation, it is important to ensure that the bearings are correctly aligned and properly lubricated.Proper alignment involves carefully positioning the bearings to minimize any misalignment or uneven loading, which can lead to premature wear and damage. By aligning the bearings correctly, engineers and technicians can maximize the load-carrying capacity and efficiency of the bearings, ultimately enhancing the overall performance of the machinery. Additionally, ensuring that the bearings are properly lubricated during installation is essential for smooth operation and preventing friction-induced wear.
When it comes to the lubrication of Angular Contact Ball Bearings, there are different types that can be used to ensure optimal performance and longevity. Some common lubrication methods include grease lubrication, oil lubrication, and solid lubricants.
Grease lubrication is a popular choice for its simplicity and ability to provide long-lasting lubrication.Oil lubrication, on the other hand, offers higher speeds and lower friction, making it ideal for high-speed applications.Solid lubricants, such as graphite or molybdenum disulfide, are often used in extreme conditions where traditional lubricants may not be effective.
