What are the characteristics of deep groove ball bearings?

Deep groove ball bearing is the most common type of rolling bearing. The basic deep groove ball bearing is composed of an outer wheel, an inner wheel, a steel ball group and a cage.

What is the difference between rubber sleeve seal and steel sleeve seal for deep groove ball bearings?

1. Non-contact sealing sleeve including stamped steel sealing sleeve (iron seal) and non-contact rubber sealing sleeve (the sealing sleeve does not contact the inner ring).

Advantages: Vibration isolation, high relative speed, low attenuation effect caused by metal closure cover, and low price.

2. It includes the contact seal cover that contacts the rubber seal cover and the labyrinth contact seal cover (single or multi vertical contact between the seal cover and the bearing inner race).

Advantages: shockproof, prevent liquid foreign matters, high noise effect.

Which should I choose between rubber sleeve gasket and steel sleeve gasket of deep groove ball bearing?

In deep groove ball bearings, there is no difference between a good seal cover and a bad seal cover, only the difference between suitable and unsuitable. For example, in a clean environment, there is no need to use contact rubber sealing cover, which will only increase the additional cost of the manufacturer. Deep groove ball bearings have no good or bad seal type. The main consideration is the location of the bearing and the environmental factors of the bearing, namely the sealing effect and friction coefficient. The seal ring has different structure, material and friction coefficient. Select the bearing with high friction coefficient at high speed, and the bearing will be damaged quickly. The other is the difference of vibration isolation effect. Therefore, many factors must be considered when selecting the correct bearing and the rubber seal or seal of the bearing.

What are the characteristics of deep groove ball bearings?

Deep groove ball bearing is the most commonly used cloud bearing. The structure is simple and easy to use. It is mainly used to support radial load, but with the increase of radial clearance of the bearing, the bearing has a certain rigid ball bearing performance and can withstand combined radial and axial loads. In addition, when the speed is fast and the liquid core ball bearing is not suitable, it can also be used to accept pure liquid core load. Compared with other bearing types (such as deep groove ball bearings), this bearing type has small friction coefficient and high speed limit. But it is not resistant to impact and is not suitable for carrying heavy objects.

After the deep groove ball bearing is installed on the shaft, it can limit the axial displacement of the shaft or housing in both directions within the axial clearance of the bearing, so it can be positioned in both directions. In addition, these types of bearings also have a certain self-aligning function. Even if the housing hole is tilted by 2 to 10 feet, it can work normally, but it has a slight impact on the bearing life.
