What is OD in bearing?
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).

What are 6203 ZZ ball bearing used for?
The 6203 is a 17 mm Ball Bearing that can be used in many rotary and factory automation applications. The 6203 Deep Groove Ball Bearings is an open style bearing. The 6203Z ball bearing is a single row raceway and single shielded. The 6203ZZ ball bearing has a single row raceway and it is shielded on each side.
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.
What is the difference between 6203 and 6203 2rs?
6203-2rsh is a bearing with a heavy duty rubber seal on each side. 6203-2rs is a bearing with a standard seal on each side.
What is a 6203 2rs bearing?
Deep groove ball bearing with seals. Single row deep groove ball bearings with seals on one or both sides are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds.
What size is a 6201 bearing?

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.
How is bearing size measured?
This can be measured in the same way as the outer diameter. Simply place the jaws of your vernier caliper around the width of the outer ring of the bearing and close it until it meets the ring. Again, it should feel snug but not tight. The value which is displayed on the caliper is the width of the bearing.
What is a 6203 2RS bearing?
What size is a 6204 bearing?

What is meant by L10 life 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.
What is L10 and L50 life of bearing?
L50 life equals five times the L10 life. In other words, to get a L50 life equal to a L10 80,000-hour life, you must specify the L50 life to be 400,000 hours.
What are the three rules of bearings?
There are 3 rules to follow when measuring a bearing: Always measure the angle in a clockwise direction. Always measure the angle from north. Always give a 3-figure bearing (E.g. 030° instead of 30°)
What is B10 life of bearing?
The B10, or Bearing life, nomenclature refers to the point at which 10% of units in a population will fail. Alternatively, you can regard it as the 90% reliability of a population at a specific point in its lifetime.
How is L10 life calculated?
1. Basic fatigue life rating L10 A bearing’s basic fatigue life rating is calculated using the number of rotations which 90% of all bearings in a specific group achieve or exceed a calculated time without failure (probability of failure: 10%).
Why are bearings written in 3 digits?
Bearings are measured clockwise from north. Bearings are always given as three figures because if you only wrote down 35°, it could easily be mistaken for 350°. On longer passages when it is necessary to run a watch keeping system, it is not unusual for there to be several navigators.
