Bearing number explain

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 is bearing number calculated?

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 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 is C3 and C4 in bearing?

The "C" rating stands for the clearance between the rings and rollers of the bearing. The greater the temperature variations the higher the C rating would be needed. C3 or C4 won't make much difference for a high rpm engine. However C4 would be preferable for a high-load engine.

How do you read bearings?

The bearing is always measured clockwise from north. The bearing is the angle clockwise from north to west subtract θ. From north to west is 270° and so the bearing is 270° – 17° = 253°.

Why do bearing have 3 digits?

known point. A bearing is a direction, expressed as a three-figure number. 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°.

What size is a 6305 bearing?

Bore diameter	25 mm
Outside diameter	62 mm
Width	17 mm

What is a 3 digit bearing?

The angle in degrees measured clockwise from North. It is common to put extra "0"s to make it a full 3 digits, so: • North is 000° • East is 090° • South is 180°

What is Z and ZZ in bearing?

2 Z / ZZ - Bearing with a metal seal on both sides. Z - Bearing with a metal seal on one side, one side open. E - Reinforced Design. P2 - Highest precision.

What is ZZ C3 in bearing?

The 2Z suffix indicates that the bearing has a steel seal on both sides. The bearings are filled with a high-quality grease and are lubricated for life. Internal play. The C3 in the product name means that this bearing has a higher (internal) clearance than normal.

What is C3 for bearing?

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 C10 bearing?

• Catalog Load Rating, C10: Constant radial load that causes 10% of a group of bearings to fail at the bearing manufacturer's.

What is cc W33 bearing?

This 23220 CC/W33 bearing is a Spherical Roller Bearing with a guide ring centred on a flangeless inner ring, two stamped steel cages, an annular groove in the outer ring with three lubrication holes and a normal radial internal clearance. The bearing's dimensions are 100x180x60.

What is a 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.

How many balls are in a 6203 bearing?

They are designed to reduce rotational friction and support loads. The load is spread evenly across the grade 25 balls and as the inner bearing race rotates so do the balls.

How do you size a bearing?

To measure the outer diameter of a bearing, place the jaws of your vernier caliper around the outside of the bearing and close it until it meets the outer edge of the bearing. It should be a snug fit, but not tight. Now, you can read the value on the caliper to find the outer diameter measurement.

What does 608 mean for bearings?

The "608" means that the bearings are from the 600 series, with a 8mm inner diameter (the width of the hole, i.e., internal bore).

What are 3 main components of a bearing?

Bearings usually consist of the following components: Two rings or discs with raceways. Rolling elements in the form of rollers or balls. A cage which keeps the rolling elements apart and guides them.

What is the bearing of 90?

Absolute bearing refers to the angle between the magnetic north (magnetic bearing) or true north (true bearing) and an object. For example, an object to due east would have an absolute bearing of 90 degrees. Thus, it is the same as azimuth.
