618 series groove ball bearing

618 series groove ball bearing

Deep groove ball bearings are manufactured as single row deep groove ball bearings and double row deep groove ball bearings. The structure of them are also divided into two structures: sealed and open type.

Application of the 618 series groove ball bearing

Features :

Deep groove ball bearings are the most common type of rolling bearings,with broad applications. They have features of small coefficient of friction, high rotation speed limit, simple structure and high precision. Deep groove ball bearings carry radial load as priority, also can carry a certain amount of axial load.

Structure:

Deep groove ball bearings are manufactured as single row deep groove ball bearings and double row deep groove ball bearings. The structure of them are also divided into two structures: sealed and open type.

Applications:

Deep groove ball bearings are widely used in the field of gearboxes, instrumentation, electric motors, appliances, internal combustion engines, vehicles, agricultural machinery, construction machinery, engineering machinery, rollerblading etc.
