What do the numbers on a bearing mean?
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.
How do I know my bearing number?
Bore size of Bearing Note : In case there is no fourth digit, then the 3rd digit indicates the bore size in mm. For example: in case of bearing 636, the bore size of the bearing will be 6mm. Thus, we can identify now that in case of bearing 6305ZZ, the third and fourth digit ’05’ means the bearing’s bore size is 25 mm.
How do you read a bearing?
The bearing of a point is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass with the point. A bearing is used to represent the direction of one point relative to another point. For example, the bearing of A from B is 065º.
How do you read bearings?
A bearing is an angle, measured clockwise from the north direction. Below, the bearing of B from A is 025 degrees (note 3 figures are always given). The bearing of A from B is 205 degrees. A, B and C are three ships.
What does Z mean on bearing?
2 Z / ZZ – Bearing with a metal seal on both sides. Z – Bearing with a metal seal on one side, one side open.
How do you measure a sealed bearing?
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 I know if my bearings are sealed?
When trying to decide whether a bearing is sealed using the AFBMA or SKF code, note the shields or seals section. If the bearing number uses the AFBMA code, look for “EE” (or “2RSI” for SKF) to determine if the bearing is sealed on both sides. This is the only way to identify whether a bearing is sealed.
What does C3 mean bearing?
Internal clearance
Internal clearance being C3 means that the bearing has room for expansion if needed between the races of the bearing, whilst holding the outer ring and moving the inner ring in a radial movement you will detect a little amount of play between the two rings.
What is bearing series and their code in bearing number?
Bearing Series and Their Code in Bearing Number The second digit of a bearing patter number indicates the bearing series. Series of a bearing denotes the toughness of the bearing.
