Ball bearings are one of the most commonly used engineering components in the world. They are everywhere from cars and bicycles to roller coasters and washing machines.
Despite their ubiquity, most people know very little about ball bearings and how they work. In this article, we'll explore five fun and creative ways to use ball bearings in your everyday life.
What are ball bearings?
A ball bearing is a rolling element bearing that uses balls to maintain separation between the bearing races. The purpose of ball bearings is to reduce rotational friction and support radial and axial loads. It does this by using at least two raceways to accommodate the balls and transfer the load through the balls.
There are two main types of ball bearings: angular contact and deep groove. Angular contact ball bearings have higher radial load capacity than deep groove ball bearings and can withstand higher speeds. Deep groove ball bearings are the most common type of ball bearing and can carry radial and axial loads.
Ball bearings are used in various applications such as wheels, gearboxes, motors and pumps. They are classified according to load capacity, rated speed and size.
The types of the ball bearing
There are four types of ball bearings: angular contact, deep groove, double row and single row. Each type has its own advantages and disadvantages, so it is important to choose the right type for your application.
Angular contact ball bearings can withstand high radial and axial loads. They are typically used in applications that require high precision, such as precision instruments and automotive engines.
Deep groove ball bearings are the most common type of ball bearing. They are capable of bearing radial and axial loads but are not suitable for high-precision applications.
Double row ball bearings can withstand higher radial and axial loads than single row bearings. They are typically used in heavy-duty applications such as construction equipment and large machinery.
Single row ball bearings are the most common type of ball bearing. They are widely used in many industries including automotive, aerospace and construction. Single row ball bearings are available in a variety of sizes, from miniature bearings for electric motors to large bearings for heavy equipment.
5 Creative uses for ball bearings
Use ball bearings to create a tactile sensory experience.
Adding ball bearings to your products can create a unique sensory experience for your customers. Ball bearings can add weight, vibration and motion to your products, making them easier to touch and play with. This can be a great way to add value to your products and make them more interesting and attractive to your customers.
If you are considering adding ball bearings to your product, there are a few things to keep in mind. First, you need to make sure that the ball bearings you are using are compatible with the material from which the product is made. Second, you need to consider the size and weight of the ball bearings used, as this affects the overall feel of the product. Lastly, you need to make sure your product is designed in a way that allows the ball bearings to move freely without jamming.

How to incorporate ball bearings into your life?
Ball bearings are amazing objects. They are simple yet complex, and they have the power to make our lives infinitely better. Incorporating ball bearings into your life is as easy as adding them to a box of old nails that you can use for various projects around the house.
Here are three ways to use ball bearings to make your life infinitely better:
- Ball bearings can make your life easier by reducing friction.
- Ball bearings can help you move faster and with less effort, making your life more productive.
- Ball bearings can make your life more enjoyable by providing a smooth and satisfying experience.
In conclusion, ball bearings are a versatile and affordable product that can be used in a variety of ways. They can be used to make furniture, improve the performance of vehicles, and even make art. With a little creativity, ball bearings can be used in almost any application.
Selecting appropriate shaft and housing tightness fits are critical in optimizing a single row radial ball bearing’s performance and life. A bearing can only perform to its full capacity when it is correctly fitted on the shaft and in the housing. Improper fits can lead to undesirable operating conditions and early failure.
Below are some of the common considerations bearing users should consider:
Direction, type, and magnitude of loads
Based on the actual applied axial and radial loads an equivalent radial load is calculated. Generally, tighter fits are required as the load increases. Further, rings subjected to circumferential loading should have tight fits. For rings subjected to only point loading, a loose fit may be used.
Inner or outer ring rotation
Typically, the ring that is rotating requires an interference fit, and the non-rotating ring would have a slightly loose fit.
The size and type of bearing specified
Thin type and miniature bearings are very sensitive to interference fits due to loss of radial play. Bearings with heavier cross sections generally require tighter fits.
Material and manufacturing tolerances of mating components.
Fit tolerances are based on cast iron or steel housings and shafts. For alloys such as aluminum (with a different modulus of elasticity), a tighter fit is required to achieve rigid seating.
Operating temperature
With tight fits and a temperature differential between the inner and outer ring, the radial internal clearance in the bearing is reduced. This must be taken into consideration when selecting the internal clearance. Additionally, if the materials used for the housing or shaft are dissimilar, they will have different coefficients of thermal expansion than the bearing rings. This must be taken into consideration to achieve rigid seating.
Running accuracy required
In order to achieve high running accuracy, the same high standard of accuracy and surface quality expected in the bearing must be applied to the shaft and housing as well. In addition, with miniature and thin type bearings irregularities on the shaft or in the housing are transferred to the relatively thin walled bearing rings.
