What Are The Different Benefits Of Using Ball Bearings?

Ball bearings have many advantages in the mechanical machines. Bearings Reduce Friction. Bearings are elements that are used to reduce the friction of certain moving parts in a machine or device. This is done by replacing sliding friction with the rolling friction.

Bearings are used to provide better linear motion or rotation around a fixed axis. Almost all ball bearings are made of steel. Since the bearing has to stand up to a lot of stress and pressure, it needs to be made of very strong steel. There are many advantages of ball bearing, some of them are-

  • Varieties-

There are thousands of ball bearing varieties exist in the market like the radial, axial, angular contact, double ball races, to 4 points of contact, ball, roller, needle, ceramic, titanium, stainless steel. This wide range of variety makes it even more attractive and interesting.

  • Precision-

They are very precise. This is one of the most important benefits of ball bearings. Precision bearings are highly used in different fields like in watchmaking, machine tools, and aerospace.

  • Aesthetic-

The different types of ball bearings are available in almost all colors and designs. Some people also see mechanical components as art, that’s what makes all the difference.

  • Adaptability-

The ball bearings are available in different dimensions but they not always meet to the application and their various needs. This is why there are small and medium manufacturers of tailored ball bearing solutions to meet the needs of different industries such as medical, building technology, automotive and consumer goods.

  • Technologies-

Different modern machines are nowadays using different types of ball bearings to get the desired results. So that the final product must be of good quality.

 

 

  • Competition-

Competition is very intense between different manufacturers of ball bearings. There are thousands of ball bearings manufacturers on the earth and this abundance creates a competition between different players in this field.

  • Omnipresence-

It has become almost impossible to avoid ball bearings because they are present in each and every sector of your life. During a day, it is not surprising to come across more than 100 ball bearings in your daily life. When you wake up in the morning and open the doors of the window, when you use the coffee machine, when you take the help of elevator at each stage you are indirectly using ball bearings.

So ball bearings have become an important part of your life completely. You are not directly in touch with ball bearings but indirectly you are always in contact with them.

9 Tips To Select The Best Bearing For Your Applications

9 Tips To Select The Best Bearing For Your Applications

Bearing selection is sometimes very tricky as there are so many types of bearings available in the market like the deep groove, angular groove, angular contact, self-aligning, spherical roller, taper roller, thrust ball and many more. Selecting a perfect bearing for your desired installation of application depends upon various factors, out of which some are:

• Deep Grove is normally used for radial and thrust loads. Thrust loads can be 2/3rd greater than the radial loads.

• Angular contact ball bearing is used to support a combined radial and thrust loads and also the heavy loads are therefore, dependent on contact angle’s magnitude. The bearings which have large contact angles support heavy thrust loads.

• For primary radial loads, the self-aligning precision balls may be used. Extra care should be taken while selecting these kinds of bearings or thrust load which are generally greater than the radial loads.

• The spherical roller bearings are best used for heavyweight radial loads and with moderate thrust. Their have various self-aligning features, which are very useful for many applications.

• Cylindrical roller bearings use the cylinders with perfect diameter and length ratio ranging as rolling elements. These Cylindrical roller bearings normally are used for heavy radial loads. Especially used for free axial movement of the shaft.

• Taper Roller Bearings are also used for heavy thrust and radial loads. The bearing is designed in such a way, that the raceways intersect at a common point on the axis thus, true rolling is obtained. It requires maximum rigidity and the bearings can be adjusted for a preload.

• For low-speed applications, thrust ball bearings can be used, where other bearings carry the radial load.

• There are bearings like straight roller thrust bearings, which are made up of series of short rollers to minimize the skidding, which causes twisting of rollers. They may be used for moderate speeds and loads.

Needle bearings are those bearings which have length at least 4 times greater than its diameter. These bearings can be used where space is the factor, and inner race is sometimes available and sometimes not. If the shaft is used as the inner race, then it is grounded and hardened. Full-compliment type of bearings is used for high loads and for low speed. Cage type is used for rotational motion and cannot support the thrust loads most of the times.

Conclusion

Load and the nature of the load, the speed of the shaft, expected life of the bearing and the nature of the environment are some of the factors which needs to be considered before buying a perfect bearing for your applications.
