What is a rear ball bearing?
A rear ball bearing is a type of rolling-element bearing that uses balls as the rolling elements. Rear ball bearings are used in a wide variety of applications, including automotive, aerospace, and industrial machinery.
Benefits of using rear ball bearings
Rear ball bearings offer a number of advantages over other types of bearings, including:
Low friction: Rear ball bearings have a low coefficient of friction, which means that they can operate with less energy loss than other types of bearings.
High speed: Rear ball bearings can operate at high speeds, making them ideal for applications where speed is critical.
Long life: Rear ball bearings have a long service life, making them a cost-effective choice for applications where reliability is important.
How to choose the right rear ball bearing
When choosing a rear ball bearing, it is important to consider the following factors:
The load that the bearing will be subjected to
The speed at which the bearing will operate
The environment in which the bearing will be used
Once you have considered these factors, you can use the following tables to help you choose the right rear ball bearing for your application.
Load ratings for rear ball bearings
| Bearing Type | Load Rating (kN) |
|---|---|
| Single-row deep-groove ball bearing | 10-100 |
| Double-row deep-groove ball bearing | 20-200 |
| Angular contact ball bearing | 30-300 |
| Cylindrical roller bearing | 40-400 |
| Spherical roller bearing | 50-500 |
Speed ratings for rear ball bearings
| Bearing Type | Speed Rating (rpm) |
|---|---|
| Single-row deep-groove ball bearing | 10,000-20,000 |
| Double-row deep-groove ball bearing | 15,000-30,000 |
| Angular contact ball bearing | 20,000-40,000 |
| Cylindrical roller bearing | 25,000-50,000 |
| Spherical roller bearing | 30,000-60,000 |
Common mistakes to avoid when purchasing rear ball bearings

Basic concepts of rear ball bearing
Rear ball bearings are a type of rolling-element bearing that uses balls as the rolling elements. Rear ball bearings are used in a wide variety of applications, including automotive, aerospace, and industrial machinery.
Rear ball bearings consist of an inner race, an outer race, and a set of balls. The balls are held in place by a cage or separator. The inner race is attached to the shaft, while the outer race is attached to the housing.
When a load is applied to the bearing, the balls roll between the inner and outer races. This rolling motion allows the bearing to support a load with very little friction.
Rear ball bearings are available in a variety of sizes and configurations. The most common type of rear ball bearing is the deep-groove ball bearing. Deep-groove ball bearings are available in both single-row and double-row configurations.
Advanced features
Rear ball bearings are available with a variety of advanced features, including:
Seals: Seals can be used to protect the bearing from dirt and other contaminants.
Shields: Shields can be used to protect the bearing from dust and other airborne contaminants.
Lubrication: Rear ball bearings can be lubricated with a variety of lubricants, including grease, oil, and solid lubricants.
FAQs about rear ball bearing
Here are a few frequently asked questions about rear ball bearings:
What is the difference between a rear ball bearing and a roller bearing?
Rear ball bearings use balls as the rolling elements, while roller bearings use rollers. Rear ball bearings are typically more compact than roller bearings, but they can support less load.
What is the difference between a single-row rear ball bearing and a double-row rear ball bearing?
Single-row rear ball bearings have one row of balls, while double-row rear ball bearings have two rows of balls. Double-row rear ball bearings can support more load than single-row rear ball bearings.
What is the difference between a deep-groove rear ball bearing and an angular contact rear ball bearing?
Deep-groove rear ball bearings have a deep groove in the inner and outer races. This allows the bearing to support loads from both axial and radial directions. Angular contact rear ball bearings have a shallow groove in the inner and outer races. This allows the bearing to support loads from only one axial direction.
