Brief introduction for deep groove ball bearing :

Deep groove ball bearings is one of the most widely used rolling bearings. It is characterized by low frictional resistance and high rotational speed. It can be used on parts with radial load or combined load of radial and axial action. It can also be used on parts with axial load, such as small power motors. Automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc, 6204 is one of deep groove ball bearing .

6204 Bearing Specification :

We can provide 6204 with three type design ,in an open, shielded (ZZ), or sealed (2RS) design.

Open bearings are supplied with a light oil coating and are used in oil bath and oil misting applications.

Sealed bearings are supplied with a contacting lip seal that excels in protecting the bearing from liquids and other foreign contaminants. The inherent design creates friction, drag, and in turn heat; factors that require consideration in high speed applications.

Shielded bearings are provided with non-contacting metal shields that protect against larger particles entering the bearing, but do not protect against liquids. They add no friction during operation and therefore do not generate heat build-up.

Ball Bearing packing :

Below here is two type of KOYO bearing color box packing for your reference ,you can choose as your need ,or we can do customized service ,if you want do your brand ,we can produce color box for you too .

First : New KOYO brand packing :

Second : Old KOYO color box packing :

6204 Ball Bearing Application :

Electric Motors

Quiet operation realized by proper clearance, recommend fitting practice. Lower noise lubricants. Suitable for all speed ranges applications requiring low noise.

Automotive Alternators

Longer life in vibrations and high temperature environments.

Automotive Starters

High reliability in periodic use of vibrations and high temperature environments.

Compressors

Long life pump rotors which compress air in low temperature and low viscosity lubrication environments.

Blowers

Quiet and stable operation on fan rotors at high speed, in environments with vibration and high temperatures

Transmissions

Compact design for light weight to achieve high performance.
