How much do you know about deep groove ball bearings?

Deep groove ball bearing is the most widely used type of cloud bearing. It is characterized by low friction resistance and high speed. It can be used for parts that accept radial loads or both radial and axial loads, as well as parts that accept axial loads, such as low-power motors, automobile.

What is the structure of deep groove ball bearing?

Deep groove ball bearings have two types: single row and double row. Deep groove ball structure is divided into two types: sealed type and open type. Open type means that the bearing is not a sealed structure. Sealed deep groove ball is divided into shockproof seal and oil proof seal. The material of the dust seal sleeve is an embossed steel plate that only prevents the dust from entering the bearing track. The type of oil lubrication is contact oil seal, which can effectively prevent the grease overflow of the bearing. The type code of insulated deep groove ball bearing is 6, and the code of insulated deep groove ball bearing is 4. With simple structure and ease to use, it is the most widely produced and widely used bearing type.

What are the characteristics of deep groove ball bearings?

Deep groove ball bearings have the characteristics of low friction resistance and high speed. They can be used for parts bearing radial load or radial and axial load at the same time, and also for parts bearing axial load.

The track grooves of the inner wheel and the outer wheel of the deep groove ball bearing form an arc with a radius slightly larger than that of the ball. In addition to radial loads, axial loads can also be applied in both directions. It is suitable for occasions with low friction torque, high-speed rotation, low noise and low vibration.

What is the type of deep groove ball bearing?

1. Deep groove ball bearing with dust cover

It is generally used under conditions that are difficult to lubricate alone, so it is inconvenient to set the lubricating oil circuit and confirm the lubrication state. Usually, the lithium series glass injected into the bearing is 1/4 to 1/3 of the internal space of the bearing.

2. Deep groove ball bearing with sealing ring

The performance, Greek filling and application of deep groove ball bearings with sealing rings are basically the same as those with dust covers. The difference is that there is a large gap between the dust cover and the inner ring. The clearance between the inner ring is small, and there is no clearance between the sealing lip and the inner ring of the contact seal bearing. The sealing effect is good, but the friction coefficient increases.
