Bearing numbers

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 size is a 6203 bearing?

Bore diameter	17 mm
Outside diameter	40 mm
Width	12 mm

How do you find the bearing number?

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 does K mean in bearing number?

Prefix: K - Cage with roller elements. L - Removable bearing ring. R - Ring with roller set. S - Roll body of stainless steel.

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'.

Why do we use 3 digits for bearings?

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 6200 bearing?

Bore diameter	10 mm
Outside diameter	30 mm
Width	9 mm

What size is a 6205 bearing?

Bore diameter	25 mm
Outside diameter	52 mm
Width	15 mm

What size is a 6303 bearing?

Bore diameter	17 mm
Outside diameter	47 mm
Width	14 mm

What size is a 6305 bearing?

Bore diameter	25 mm
Outside diameter	62 mm
Width	17 mm

What is the bearing of 150?

The position of a point P on a bearing of 150° is shown in the following diagram. The position of the point P is 180° – 150° = 30° east of south. So, the direction is S30°E.

What is my bearing size?

To find the outer diameter of a bearing, you'll need to measure from one side of the outer ring to the other. 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.

What does V mean on a bearing?

"V-shaped" marking A “V-shaped” marking on the outside surface of the outer rings of universally matchable single direction bearings indicates how the bearing set should be mounted in relation to the axial load. The “V-shaped” marking points toward the side face of the inner ring that can support axial load.

What is C3 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 does E mean in SKF bearing?

SKF self-aligning ball bearings. Suffixes - Internal design. E. Optimized internal design for increased load carrying capacity.

Can I use a C3 bearing?

A bearing with C3 spec is usually used where heat is a concern. It leaves a bit more space for the bearing to expand due to heat build up. If you use a tighter bearing in a high heat situation, the load on the bearing will be much greater and the bearing will fail prematurely.

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°)
