Ball bearing nomenclature

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.

What is bearing nomenclature?

A bearing number is composed of a basic number and a supplementary code, denoting bearing specifications including bearing type, boundary dimensions, running accuracy, and internal clearance.

What is C1 C2 C3 in bearing?

These are the 5 most common C codes for internal bearing play: C1, C2, C3, C4 and C5. If a bearing has a C code, it offers extra internal clearance. C1 offers the least extra clearance, C5 offers the most extra clearance. The extra margin C3 offer is considered 'normal'.

What is a 6203 ball bearing?

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 size is a 6203 bearing?

Bore diameter	17 mm
Outside diameter	40 mm
Width	12 mm

What is ID and OD of 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 is Z and 2Z in bearing?

2 RS - Bearing with rubber seal on both sides. RS provides a better seal but more rolling friction than 2Z. RS - Bearing with rubber seal on one side, one side open. 2 Z / ZZ - Bearing with a metal seal on both sides. Z - Bearing with a metal seal on one side, one side open.

What does C3 mean in 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 difference between Z and ZZ bearing?

A: Z designates the bearing shield, zz is a two sided shield bearing. A single sided shield bearing, "z". Helpful?

What is C10 in bearing?

• Catalog Load Rating, C10: Constant radial load that causes 10% of a group of bearings to fail at the bearing manufacturer's. rating life. – Depends on type, geometry, accuracy of fabrication, and material of. bearing.

What is ZZ C3 bearing?

The 6206-2Z/C3 SKF is a deep groove ball bearing with a single row design. Deep groove ball bearings have a straight forward design, are robust in operation and are easy to maintain. Deep groove ball bearings reduce rotational friction and support both radial and axial loads.

What are the 3 rules of bearing?

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 size is a 6303 bearing?

Bore diameter	17 mm
Outside diameter	47 mm
Width	14 mm

What size is a 6200 bearing?

Bore diameter	10 mm
Outside diameter	30 mm
Width	9 mm

What size is a 6204 bearing?

Bore diameter	20 mm
Outside diameter	47 mm
Width	14 mm

What size is a 6205 bearing?

Bore diameter	25 mm
Outside diameter	52 mm
Width	15 mm

What size is a 6306 bearing?

Bore diameter	30 mm
Outside diameter	72 mm
Width	19 mm

What size is a 6207 bearing?

This SKF 6207 deep groove ball bearing is unsealed, has a standard cage, and has CN internal clearance. It has a 35mm ID, a 72mm OD, and a 17mm width. This single-row ball bearing has deep groove geometry for supporting radial and axial loads at high speeds.

What is DN value in bearing?

DN Factor, also called DN Value, is a number that is used to determine the correct base oil viscosity for the lubrication of various types of bearings. It can also be used to determine if a bearing is the correct choice for use in a given application. It is a product of bearing diameter (D) and speed (N).
