Example Use of Ball Bearings
Precautions of Ball Bearings
When the precision of the shaft and Ball Bearings housing is poor, the bearing will be affected, and its due performance will not be exerted. For example, the poor precision of the mounting part with the bearing will cause relative inclinationof the inner and outer rings.
At this time, besides the Ball Bearings load, the edge load will be increased additionally, which will shorten the fatigue life of the bearing, and even more seriously, it will lead to damage such as cage breakage and sticking.
Please use the following special mounting tool for installation and removal

Frequently asked question (FAQ)FAQ
- Question:Question: What is the difference between ball bearing and roller bearing?
- Answer:Answer: The contact between ball bearing and raceway is point contact, and the contact surface is oval when stressed. Because of the point contact, resisting force value is small, and the ball bearing is suitable for the application conditions of low torque and high rotational speed. They also have the characteristics of low noise. Ball bearings have low loading capacity but can bear radial and axial loads. The contact between roller bearing and raceway is line contact, and the contact surface is square when stressed. Because of the line contact, the torque of roller bearing is higher than that of ball bearing, and its rigidity is higher. Roller bearings have higher loading capacity, and cylindrical roller bearings have retaining edges to bear slight axial loads.
- Question:Question: What is the classification of bearings according to the shape of rolling elements?
- Answer:Answer: Rolling bearings are mainly divided into: ball bearings and roller bearings. Among them, ball bearings are divided into: deep groove ball bearings, angular contact bearings and radial thrust ball bearings. Roller bearings are divided into: cylindrical roller bearings, needle bearings, cone roller bearings and self-aligning roller bearings.
- Question:Question: What is the classification of bearings according to load direction?
- Answer:Answer: Bearing are divided into: radial bearings and thrust bearings according to the load direction. Among them, radial bearings are divided into: radial thrust ball bearings and radial roller bearings. Thrust bearings are divided into: thrust ball bearings and thrust roller bearings.
- Question:Question: What is the basic rated life of rolling bearings?
- Answer:Answer: The basic rated life of rolling bearings refers to the total number of revolutions that 90% of the ball bearings can rotate without peeling when eleven groups of ball bearings of the same kind and specification rotate respectively under the same conditions.
- Question:Question: Can double shielded stainless steel deep groove ball bearings be directly used in corrosive environment?
- Answer:Answer: The antirust performance of the material of double shielded stainless steel deep groove ball bearings is weaker than that of SUS3XX series stainless steel. Do not use it directly in corrosive environment.
