About Ball Bearings

Ball bearings, cylindrical roller bearings, tapered roller bearings, and needle bearings are four types of bearings. Ball-type bearings are the most common out of all four due to their diverse applications. But you can still contemplate the alternatives before deciding on the type. Some comparison parameters include load, speed, sealing system, and rigidity. And if ball bearings are what comes out the best, it is time to explore more about them.

The whole purpose of a bearing in a mechanical device is to allow rotational movement by transferring notable loads. Primarily, these bearings induce quality in a product, including durability and high precision. And when installed perfectly, the product works at high speed with minimal noise and vibration. Indeed, there are other technical and functional aspects of this accessory, which depend on varying applications. Here, on this page, we focus on ball bearings, whose purpose is to reduce rotational friction while supporting both radial and axial loads. You can be a professional or a DIY enthusiast. The first thing to know is the different types available in the marketplace. 

Ball bearings types

On a broad brush, there are two types of ball bearings: open-style and shielded-style bearings. The latter contains metal shields on either one or both sides. It prevents dirt and debris from affecting the smooth operation of the bearing. Along with that, the shielded style also allows the free flow of oil through the bearing. But these two variants aren’t enough for some applications. These two variants have subcategories that you can explore for the perfect functioning of the product. That being said, if you are looking to buy ball bearings near me, you should dwell more on the variants.

Self-aligning ball bearing

A common structure of any ball bearing has an outer and inner ring having a ball assembly in between. As the name suggests, the self-aligning type can tolerate minor misalignments, which can be a result of incorrect mounting. Also, the structure of this type is how the outer ring provides minimum support to the ball assembly. The applications of this type restrict themselves to light axial load applications. Gearboxes and final drive transmissions are the most common applications of self-aligning ball bearings.

Deep groove ball bearing

There are these wide applications of this type of bearing. A few common uses can be seen in electric motors, vehicle motors, office machinery, garden tools, and many more. Well, there is a reason behind such wide applications. The groove type bearing is very flexible in terms of load support and different arrangement. Even more products within the groove type inherit the same features. For example, you can purchase them in a seal, shield, and snap-ring arrangement, and they will support axial and radial loads both.

Linear ball bearing

This type of bearing has been named linear because of its design. It comprises two linear ball bearings integrated within four rods on alternate sides of the base. A positive aspect of this type is that it provides self-lubrication technology, due to which you get optimum performance and reliability from the product. Applications of this type are endless. You can find linear bearing mounting in precise instrumentation, robotic assembly, cabinetry, cleanroom environments, and X-ray & imaging equipment.

Thrust ball bearing

This is another type other than self-aligning one that only supports axial loads. Furthermore, there are in total five variants: Cylindrical, tapered, & spherical roller thrust bearing. And the rest two are fluid and magnetic bearings. Thrust bearings with such varieties find their usage in higher speed applications, such as automotive and aerospace industries.

Tips on how to buy Ball Bearings

Here, we are assuming you have scrolled through the products online, and if not, you can do that on our shopping search engine. You will see an alphanumeric code written as the product name of ball bearings. Now, when you know what we are talking about, you may be wanting to decode those alphanumeric digits. So, here is a brief guide to walk you through it step by step.

  • Bearing type – The first digit you will see is the bearing type. It ranges from 1 to 7, where one is a self-aligning ball bearing, the second is spherical roller bearing, the third is tapered roller bearing, and the fourth is deep grove double-row ball bearing. Similarly, five, six, and seven digits refer to deep axial groove, single row deep groove, and single row angular contact bearing.
  • Bearing series – The second single digit of the bearing series starts from zero to four, and then the last two codes are eight and nine. The first five are as follows: extra light, extra light thrust, light, medium, and heavy. And the last two, that is, eight and nine come under thin section and very thin section bearing series.
  • Bore size – The bore size is usually in millimetres that you can predict by checking the two digits after bearing the series code. The codes are as follows: 00, 01, 02, 03, 04, 05, and 10. The size these codes represent is 10mm, 12mm, 15mm, 17mm, 20mm, 25mm, and 50mm, respectively.
  • Details – The last digit/s refers to common seals, shields, and other details. This code can be alphanumeric or just numeric. Speaking of codes, if you see K, E, and RS, you can predict the product as a tapered bore, increased load-carrying capacity, and a product with the rubber seal on one side. However, the 2RS code means a rubber seal on two sides. Another code P indicates mould glass fibre reinforced polyamide 6,6 cage. Then, Z and ZZ code indicates a metal shield on one or two sides.

We hope the guide will help you save your time while shopping for the right ball bearing. Another time-saving thing is knowing a list of brands beforehand, so when you see these names popping up, you know you are going the right way in your research. Some of the brand names include FAG, RS, Timken, HCH Bearing, and NMB. You can find all of them on our shopping platform,

Question & Answer

How do ball bearings help reduce friction?

The rougher the surface, the more friction is produced. And ball bearings have a smooth surface, but this is not the only reason for reduced friction. They also roll over each other to lessen the coefficient of friction.  Some common examples are fidget spinner and yo-yo. From toys to aerospace, the application of ball bearings are wide and diverse. Although various application needs make their manufacturing slightly different, the purpose remains the same, that is to reduce the friction.

Can ball bearing be drilled?

The answer is yes only if you have the right equipment for it. For example, you can use a mill to drill the hole first into the plate and then into the ball. However, the steel ball bearings are most likely case-hardened that cannot be drilled with standard drill bits. In that case, you can use a grinder to grind a small flat spot to drop the ball into it, tighten the clamps, and drill the steel balls. You can also tap the ball with this setup. This is one of many applications to drill the bearings. You can search more and use the one most suitable.
