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: What is the contact angle of this angular contact ball bearing?
Answer:Answer: The contact angle of this angular contact ball bearing is 25 degrees, and the domestic common usage rate is relatively high.
Question:Question: Is the universal pairing a single or a double one? What is the accuracy grade?
Answer:Answer: The universal pairing type is sold individually and the accuracy grade reaches P4 grade.
