Bearing names

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 the most popular bearing?

Deep groove ball bearings are the most widely used bearing type and are extremely versatile. They have low friction and are optimized for low noise and vibration which enables high rotational speeds. The purpose of deep groove precision ball bearings is to reduce rotational friction and support radial and axial loads.

What are the three common bearing types?

The most popular types of bearings are ball bearings, Tapered Roller Bearings, Ball Thrust Bearings, and Roller Thrust Bearings etc.

What does ZZ mean on bearings?

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 size is a 6203 bearing?

Bore diameter	17 mm
Outside diameter	40 mm
Width	12 mm

Where are different bearings used?

They can support axial loads in two directions besides radial loads. Ball bearings are used for controlling oscillatory and rotational motion. For example, in electrical motors where the shaft is free to rotate but the motor housing is not, ball bearings are used to connect the shaft to the motor housing.

What is bearing and example?

In mathematics, a bearing is the angle in degrees measured clockwise from north. Bearings are usually given as a three-figure bearing. For example, 30° clockwise from north is usually written as 030°.

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.

How many types of Bering are there?

There are at least 6 common types of bearing, each of which operates on a different principle: Plain bearing, consisting of a shaft rotating in a hole.

What is the biggest bearing in the world?

Sperm whales are almost 18 meters long. So are articulated buses and tractor trailers. The width of a four-lane highway with an exit lane is also 18 meters. And that's the diameter of the world's biggest slewing bearing.

How many types of bearings do we have?

Bearings are of only two types, friction, and antifriction bearings, and further subdivided these two like solid bearing, ball bearing, roller bearing, etc.

What are the two basic types of bearings called?

Bearings come in two main types: thrust bearings (which maintain a round object's rotation and position while thrust is applied, like in a Lazy Susan), and radial load bearings (keep a spinning object in position in the radial direction, like in a skateboard wheel).

What are the two primary bearing types?

Ball and roller bearings The two basic types of rolling element distinguish the two basic types of rolling bearing: Ball → ball bearing. Roller → roller bearing.

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'.
