One-Way Thrust Ball Bearing

One-way thrust ball bearings are a common type of bearing used to withstand one-way thrust loads. It is composed of an outer ring, an inner ring, a steel ball, a cage and a cover. In the field of industrial machinery, thrust ball bearings are usually used to support high-speed rotating workpieces and withstand the thrust load generated by rotation. This paper will introduce the structure, working principle, application field and advantages and disadvantages of unidirectional thrust ball bearing

Product Details

The structure of one-way thrust ball bearing is relatively simple, mainly composed of outer ring, inner ring, steel ball, cage and cover.

The outer ring is the outermost part of the thrust ball bearing, usually made of steel material. The inner ring is located inside the outer ring, and the gap between the outer ring is the movement space of the steel ball. The steel ball is the key component connecting the outer ring and the inner ring, which can provide the function of carrying the thrust load. The cage is used to maintain the relative position of the steel balls to avoid collision or congestion. The cap is used to encapsulate the thrust ball bearing to prevent the leakage of dust, contaminants and lubricants.

1. Strong bearing capacity: thrust ball bearings can withstand large thrust loads, suitable for heavy load conditions.

2. Small friction: the steel ball rolls on the contact surface, reducing friction and wear.

3. High speed: thrust ball bearings can adapt to the requirements of high-speed rotation.

4. Simple structure: The structure of thrust ball bearings is relatively simple, easy to process and install. However, one-way thrust ball bearings also have some disadvantages:

5. Directivity: one-way thrust ball bearings can only withstand one-way thrust load, can not withstand two-way thrust.

6. High lubrication requirements: the lubricant in the bearing needs to be checked and replaced frequently to ensure the normal operation of the bearing.
