Your Complete Guide to Reading Bearing Numbers

Are you looking for bearings for your facility or machine? From afar, they might appear similar, but the truth is that they are different. Bearings are designed with varying materials and specifications to suit different equipment and applications. If you make a mistake and select the wrong bearing, it can result in the following problems:

  • Underperformance.
  • Expensive machine repair.
  • Regular downtimes.
  • Injuries and loss of life.

 

As you can see, these are problems you do not wish to face because they can ultimately slow down your production, reduce profitability, and even cause total failure of your machine or system. So, to avoid the challenges, you need to select and use only the right bearings.

 

The lovely thing about bearings is that they come with identification numbering that you can easily follow. The number on every bearing provides all the information you need, but it is important first to know how to read them. To help you understand these numbers more effectively, here is a comprehensive guide to bearing nomenclature.

 

A Simplified Guide to Bearing Numbers

 

If you pick and check any bearing, it has a digit-letter type of code. A good example is S 6200 2RS. The combination of these numbers is carefully done and signifies several things, including, the type, series, size of the bore, and sealing details. Here is a demonstration of how to go about interpreting bearing numbers.

In this case, for demonstration purposes, we are going to use bearing “S 6200 2RS.”

 

1. Start by dividing the number into three parts. See the demonstration.

  • S (Prefix).
  • 6200 (Basic Number).
  • 2RS (Suffix).

2. Then, get a little deeper to determine what every code means.

  • The Prefix is used to indicate the components used by the manufacturer to design the bearing. In the case of prefix "S", it implies that the bearing was designed using stainless steel. Here are other prefixes and what they mean.

Prefix

Component

K

Bearing cage designed with roller element

L

The bearing ring is removable

R

The bearing comes with a roller set

S

The roll body is designed using stainless steel

W

Made using stainless steel and features deep grooves

 

  • The basic number is an important code when trying to identify a bearing. The first digit of the basic number helps to identify the type of bearing. There are eight bearing types, numbered from 1 to 8. See the table below:

 

Code (number)

Bearing Type

1

Self-aligning ball bearing

2

Spherical roller bearing

3

Double row angular contact ball bearing

4

Double row ball bearing

5

Thrust ball bearing

6

Single row deep groove ball bearing

7

Single row angular contact bearing

8

Felt seal bearing

In our example, "S 6200 2RS," the first digit of the basic number is "6," so it means that we are dealing with a "single row deep groove ball bearing." Let’s check the meaning of the other numbers.

The second digit of the basic number is the bearing's series, which is used to denote the toughness. Number "2" on our example indicates that the bearing is light. Since we had earlier identified that the bearing on our example is a “single row deep groove ball bearing,” we can rightly add that it has “light toughness.” Other numbers used to denote toughness include:

 

Series Code

Series Code Meaning

0

Extra light

1

Extra light thrust

2

Light

3

Medium

4

Heavy

8

Extra thin section

9

Very thin section

 

The last two digits of the basic number denote the bore size of the bearing. See the table below to see the different bore sizes.

 

Third & Fourth Digits

Bore size (mm)

00

10

01

12

02

15


Since the third and fourth digits on our example “6200," simply call them the last two, have the code “00,” it means that we have a single row deep groove ball bearing” of light toughness and bore size of 10 mm.

  • The last part or the suffix is used to indicate the type of sealing. Here is a complete breakdown of suffixes.

Suffix (The last three codes)

What do they Mean?

Z

Has one side shielded

ZZ

Both sides of the bearing are shielded

RS

Only one side is sealed

2RS

Both sides are sealed

V

One-sided non-contact type of seal

VV

Both sides non-contact seal model

NR

Snap ring & groove


From the above table, we can now tell the meaning of our example, 2RS. It indicates that both sides of the bearing are sealed.

 

3. We have now decoded the meaning of all the numbers and codes for our bearing sample, S 6200 2RS. So, we can comfortably say that the bearing is a single row deep groove ball bearing of light toughness, bore size of 10 mm, and sealed on both sides.

Using this guide, you can now decode the numbers and codes on bearings so that only the right models are purchased for your equipment.
