roller bearing

Deep groove ball bearings, as the most representative rolling bearings, are widely used and very durable. The deep groove ball bearing has the advantages of small friction coefficient, high limit speed, simple structure and easy to achieve high manufacturing precision.

Although there are many kinds of modern bearings, their basic structure is roughly the same as the bearing structure conceived by Leonardo Da Vinci about 500 years ago. The components of the bearing are: bearing ring, rolling body, cage and bearing cover.

Bearing ring: a ring part of a radial rolling bearing having one or more raceways.

Roller: The part that rolls between the raceway rings (the roller has "ball" and "roller").

Cage: To avoid contact between rolling elements, so that the rolling elements to maintain a certain distance parts.

Bearing cover: the inner anti-grease leakage ability, the outer protection bearing dust.

Raceway ring, rolling body, cage and bearing cover, each play a different role. These actions cooperate with each other so that the bearing can rotate smoothly. However, with only these component parts, the bearing still cannot "stable" continue to rotate smoothly.

In order to ensure that the bearing can "stable" and smooth rotation, it is necessary to reduce the friction of the rolling movement and prevent the wear of the parts. "Lubricants" can do this. The "lubricant" of the bearing mostly uses semi-solid (paste) "grease" and liquid "lubricating oil". In addition, the "lubricant" also reduces the internal heat of the rotating bearing and extends the life of the bearing. Therefore, "lubricant" is also an "important item" to ensure the "stable" smooth rotation of the bearing.

Bearing parts include raceway ring, rolling body, cage, they each play different roles, these roles cooperate with each other, the bearing can rotate smoothly. Moreover, the "lubricant" can reduce the friction of rolling motion and prevent the wear of parts. Each part plays its own important role, and the bearing can continue to rotate smoothly in a "stable" manner.
