How do I calculate bearing size?
How Bearings Are Sized. Bearings are measured by their inner diameter, outer diameter, and width; the size of a bearing is normally listed as such: ID x OD x W. These measurements are normally taken in millimeters, but can be converted to inches.

What is the formula of bearing?
Bearing Rating Life Calculation
C = Dynamic Capacity (dN or Lbs) P = Equivalent Bearing Load (N or Lbs) N = Rotating speed in RPM. e = 3.0 for ball bearings, 10/3 for roller bearings.
How is bearing ID and OD calculated?
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).

What is life of bearing?
Bearing life is essentially the length of time a bearing can be expected to perform as required in predefined operating conditions. It is based primarily on the probable number of rotations a bearing can complete before it starts showing symptoms of fatigue, such as spalling or cracking due to stress. Ref: TI/E/0102.
What is L10 life of bearing?
The L10 life is the number of revolutions or hours that 90% of a group of apparently identical bearings will complete or exceed before fatigue is expected to occur. In other words, 10% of the group is not expected to achieve the L10 life.

What size is a 6803 bearing?
The 6803 17 mm Ball Bearing Inner Dimension 17mm X Outer Dimension 26mm X Width 5mm is an open style ball bearing designed for high rotational speeds and high dynamic loads.
What is a 6804 bearing?
The 6804 is a 20 mm Ball Bearing that can be used in many rotary and factory automation applications. The 6804 Deep Groove Ball Bearings is an open style bearing. The 6804Z ball bearing is a single row raceway and single shielded. The 6804ZZ ball bearing has a single row raceway and it is shielded on each side.
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.
What is basic life rating?
Basic rating life (L10)
Defined “rated life at 90% reliability under normal operating conditions.” This is the “total rotational speed at which 90% of the bearings can rotate without causing material separation when the same group of bearings is operated under the same conditions.”
What is L10 and L50 life?
L10 life is also referred to by manufacturers as the `minimum expected life’. L50 life: Or average life. Although the L10 life is the proper method of specifying fatigue life per the ABMA, another term is often used in the industry.
How do you calculate L10?
Count the number of vehicles passing by the site during the interval for which L10 must be calculated. For example, to calculate L10(18 hr) count the number of vehicles during a given day, between 6 am and midnight. That is considered a representative 18-hour interval.
What is 2RS bearing?
The 2RS stands for 2 rubber seals. One on each side of the bearing. So the RS denotes only one side is sealed with a rubber seal and the other is exposed and not sealed. The rubber seal is simply a rubber coating placed over a metal cover to assist in preventing contaminates from entering the bearing.
