# How do you find the bearing number?

## How do you find the bearing number?

The first digit indicates the width or height series (dimensions B, T or H). The second digit identifies the diameter series (dimension D). The last two digits of the basic designation identify the size code of the bearing bore. The size code multiplied by 5 gives the bore diameter (d) in mm.

What is the hardest ball bearing?

Steel. This is the standard steel for most ball bearings. It is harder than stainless steel meaning greater life ratings. It also has superior low noise qualities to standard 440 grade stainless steel.

How can you tell the quality of a bearing?

The rocking test is where the wheel bearing will be checked for quality by applying pressure to the top and bottom of the wheel. This creates a rocking motion on the wheel. If there is any open ended free play happening, this means the bearing is unstable and must be replaced.

## Which bearing is the best?

Angular contact bearings are the best bearing choice for high-speed applications. One reason is that the balls are smaller and smaller balls weigh less and produce less centrifugal force when rotating.
