How do you find the bearing number?

What is a Bearing Number?

  1. The first number i.e. ‘6’ represents the “type of bearing”.
  2. The second number i.e. ‘2’ represents the “ bearing series”
  3. The third and fourth number i.e. “03” represents “bore size”
  4. And the last two letters i.e. “RS” represents the “Sealing/ Seal”

How do you choose the right bearing?

When choosing a bearing, you must consider several important factors. The first factor to consider is the load that the bearing can support. Each type of bearing is specifically designed to support an axial or radial load. Some bearings can support both loads: in this case we refer to a combined load.

How do I know what size roller bearings to get?

You can measure the dimensions of a bearing by using a vernier caliper like the one below or measuring accurately with a ruler. All bearings will have an inner diameter (ID), an outside diameter (OD) and width (W). Bearings are sometimes referenced by these dimensions, in that order: ID x OD x W.

How do you order bearings?

Measuring your bearing: Most bearings are measured in three ways, the inside diameter or (ID), the outside diameter or (OD) and the width or (W). It is important to note that our bearing measurements are all done in the following order: Inside diameter (ID) x Outside diameter (OD) x Width (W).

How do you read Timken bearing numbers?

How do you identify a roller bearing?

Grooves or raceways are cut into the inner and outer rings to guide the rolling element. These are the most common, yet diverse, bearing family. Therefore, there are five primary categories to know when you identify bearings: radial ball, cylindrical roller, spherical roller, tapered roller and needle bearings.

Which type of bearing is used for very heavy radial load?

Explanation: For heavy Radial load Self-aligning roller bearing is used.

Which bearing can carry small misalignment?

Spherical roller bearing
Spherical roller bearing raceways are inclined at an angle to the bearing axis. Instead of straight sides, the rollers have spherical sides that fit onto the spherical raceways and accommodate small misalignments.

How do I identify my Timken bearings?

What do you need to know about bearing codes?

Engineers can use the code to configure a bearing with the features required for their specific application (a stainless steel deep groove ball bearing with a metal seal on each side, for example). While some manufacturers adhere to this numbering system, others have developed their own.

How is the bore size of a bearing calculated?

It is the inner diameter of the bearing and measured in millimeters. In general, the bore size is equal to five times the third and forth digit of bearing’s patter number. However, from ‘0’ to ‘3’, this formula does not imply.
