Product Overview of Ball Bearings

・Deep groove Ball Bearings is the most commonly used rolling bearing. It is of simple structure and easy to use.
・The material of this Ball Bearings is equivalent to SUS420, which has a certain antirust ability.

Product Features of Ball Bearings

・The U-shaped roller is generally used for round belt transmission, which can achieve high linear speed.
・The U-shaped groove of the Ball Bearings can prevent belt deviation and improve transmission accuracy.
・The use of U-shaped rollers can reduce the accuracy requirements of the installation reference, greatly reducing the accuracy requirements for the installation reference plane, and saving assembly time and effort.

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
Bearing heater
Precautions
Proper installation of the Ball Bearings heater can guarantee a long life of the bearing.
Rolling bearings are reliable mechanical components with long service life if they are installed and maintained correctly.
After the induction heater is used for heating, the bearing expands outward in the cylindrical direction, which can avoid the damage during installation. Induction heater is one of the most scientific heating methods, which does notneed preheating, and can be heated to 110℃ in a few seconds or minutes depending on the weight of bearings, without damaging the prior lubrication
 
Bearing puller
Precautions
When the installation state of the Ball Bearings is in the following situations, the special puller can be used for disassembly.
(a) Shaft shape: cylindrical shaft, Inner diameter shape of bearing inner ring: cylindrical hole.
(b) Shaft shape: cylindrical shaft, inner diameter shape of bearing inner ring with tight bushing: tapered hole.
(c) Shaft shape: tapered shaft, Inner diameter shape of Ball Bearings inner ring: tapered hole. In either state, the lock nut of the shaft (or the lock nut of the tight bushing) must be released during disassembly, and the lock nut must beplaced in a loose state.

Frequently asked question (FAQ)

Question: What is the difference between ball bearing and roller bearing?
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: What is the classification of bearings according to the shape of rolling elements?
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: What is the classification of bearings according to load direction?
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: What is the basic rated life of rolling bearings?
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: Can double shielded stainless steel deep groove ball bearings be directly used in corrosive environment?
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.
