Radial ball bearings are designed to handle radial loads, which are perpendicular to the axis of rotation. They are widely used in numerous applications including electric motors, fans, and pumps, where they provide low friction and high-speed operation. The number of applications for ball bearings is endless. All markets including Industrial, Automotive, Aerospace and Defense, as well, Robotics and Agriculture apply the use of  radial ball bearings extensively in their design.

Radial ball bearings and angular contact ball bearings are two common types of ball bearings that differ in their design, load capacity, speed capabilities, and application. By understanding the advantages, disadvantages, and applications of each type, engineers can choose the right bearing for their needs and ensure optimal performance and reliability.

Fortunately, a damaged hub assembly is easy to spot once you have your wheels jacked up off the ground. If at all possible, check your wheels two at a time – either both front wheels or both back ones. You can often spot a broken wheel bearing simply by comparing the behavior of two wheels after you spin them at the same time. If one of them shudders, slows down, or grinds to a stop before the other, it likely has a bad bearing.

Radial Ball bearings come in all types of designs making them versatile for use in a majority of applications. Radial ball bearings come in single row, double row, thin section and other configurations making them ideal for both standard and  high speed, low and high loads and useful if properly selected for  not only radial loads but can handle some axial and combined loads with limits. Make sure you evaluate the use of ball bearings completely before considering other options because these bearings are going to be the most economical and easy to find and replace in the marketplace.

Ease of maintenance is another significant advantage of radial ball bearings. They require minimal upkeep, and their lubrication needs are straightforward, contributing to lower overall maintenance costs. Moreover, radial ball bearings operate quietly due to the rolling elements, which is advantageous in noise-sensitive environments.

Angular contact ball bearings  have high-speed capabilities due to their low-friction design. Angular contact ball bearings provide high precision and accuracy due to their ability to maintain contact with both inner and outer raceways.

Angular contact ball bearings are designed to handle both radial and axial loads, thanks to their unique construction. The inner and outer ring raceways are offset relative to each other in the direction of the bearing axis, allowing them to support high axial loads in one direction and moderate radial loads. This design feature makes them highly suitable for applications requiring combined load support.

When you discover a damaged wheel hub assembly, make sure it’s replaced with either OEM parts from your manufacturer or quality aftermarket replacement parts like WJB’s that meet the same standards. Making sure your vehicle is running on healthy wheel hub assemblies is a vital part of keeping your vehicles – and you – safe on the road.

In the longer term, you need to check your wheel hub assemblies if you notice uneven or abnormal wear on your tires or brake components (rotors, pads, and discs). If you let a professional mechanic handle your tire rotations and brake maintenance, they should perform routine hub assembly checks while they do these tasks. If you like to handle your own maintenance, though, it’s especially important to make sure your bearings are in good working condition.

Angular contact ball bearings are also known for their rigidity. The preloading process, which applies a constant axial load during assembly, increases the stiffness of the bearing assembly, reducing deflection and improving accuracy under load. This rigidity is particularly beneficial in precision applications where maintaining alignment and reducing vibration is crucial.

To check individual wheel hub assemblies, you need to look for “play”. “Play” is any looseness in the wheel’s connection to the axle when it’s fully bolted down. You can check for play by grasping the wheel at its top and bottom, and pushing one side while pulling the other. You shouldn’t be able to wiggle the wheel to any significant degree this way; if you can, then the wheel has a dangerous amount of play.

Damaged wheel hub assemblies may fail catastrophically, causing you to lose control of your vehicle. This is a worst case scenario and few people suffer through it. A damaged assembly still impedes the proper functioning of your car, though! It can increase the wear and tear on other vital components including your brakes and tires. By reducing those parts’ effectiveness, a damaged wheel bearing can compromise your safety while you’re on the road.

One of the key benefits of angular contact ball bearings is their ability to operate at high speeds while maintaining stability and precision. They are constructed to withstand high rotational speeds without compromising performance, making them ideal for applications where both speed and accuracy are critical. The contact angle, which can be adjusted during manufacturing, further enhances their load-carrying capacity and performance under axial loads.

When it comes to choosing the right bearing, engineers should consider their application requirements and determine which type of bearing is most suitable. If the application involves only radial loads, then a radial ball bearing may be the best choice. However, if the application involves mixed loads or high-speed operation, then an angular contact ball bearing may be the better option. Do not without proper investigation assume that one of these types of bearings is the only way to go. Both types of bearings can equally be used in a lot of applications so it would be prudent to look at the economical reasons and availability of types before specifying one over the other.

Double row angular contact bearings are designed to handle especially heavy loads and can support axial loads in both directions. The double row version is suitable for designs where rigid and axial guidance is necessary. High precision versions of these bearings are used extensively in high speed spindles, machine tools and robotics. Many high technology designs in Aerospace, Industrial and Scientific areas are good candidates for using Angular contact bearings needing pure thrust or a combination of both radial and axial load requirements.

Some people said, a car is a collection of thousands of carefully-designed parts that are needed their attention to maintain with. When it comes to your wheel hub assemblies, you definitely need to muster your patience and go the extra mile to make sure they’re in good working condition; these components are vital in keeping your car safe and efficient.

In terms of lubrication, angular contact ball bearings require careful management to ensure optimal performance and longevity. They typically use grease or oil, and the lubrication system must be designed to accommodate the high-speed operation and axial load support. Proper lubrication minimizes friction and wear, contributing to the extended service life of these bearings.

Although modern wheel hub assemblies (also known as wheel bearings) are designed to last as long as your car, they’re subjected to such tremendous strain that hub damage is fairly common. Most drivers will have to deal with a damaged hub assembly at some point in their vehicle’s lifetime.

By analyzing these factors, engineers can determine which type of bearing is most suitable for their application and select the appropriate bearing size, clearance, and preload.

Angular contact ball bearings are designed to handle both radial and axial loads, which are parallel and perpendicular to the axis of rotation, respectively. They have a variety of  contact angles that allows them to withstand high axial loads without deformation, making them suitable for applications that require high precision and speed.

Ball bearings are used in a wide range of mechanical applications to reduce friction between two moving parts. Radial ball bearings and Angular contact ball bearings are two common types of ball bearings that differ in their design and application. This article will explore the advantages, disadvantages, and applications of each type, providing a comparison to help engineers choose the right bearing for their needs.

Super precision bearings

Radial ball bearings, also known as deep groove ball bearings, are essential components in many mechanical applications due to their numerous advantages. These bearings are engineered to support both radial and axial loads, making them versatile and capable of handling various loading conditions. Their rolling element construction significantly reduces friction, enhancing efficiency and minimizing energy consumption. This low-friction characteristic is particularly beneficial in high-speed applications where maintaining low resistance is crucial.

There are a lot of different signs you may run into during day-to-day driving that can indicate a problem with one or more hub assembly on your car. Grinding, roaring, knocking, or popping sounds from your wheels can indicate a bad bearing. These can be constant or only noticeable when you turn; they’re usually not audible unless you’re moving faster than 30 MPH.

Radial ball bearings and angular contact ball bearings differ in their design, load capacity, speed capabilities, and application. Radial ball bearings are suitable for handling radial loads with some limited capacity for both radial and axial, while angular contact ball bearings are designed for axial loads with an ability to handle both radial and axial loads when installed correctly. Angular contact ball bearings are often used in higher speed applications than radial ball bearings, but both are capable of high speeds.

These bearings are generally offered in both single and double row designs. The single row design has a solid inner and outerring and the balls are retained using a steel, phenolic brass or polymide cage. The races are offset from each other along the bearing axis.

Angular contact ball bearings can handle both radial and axial loads, making them suitable for applications with combined loads.
