Product Overview of Ball Bearings

・ Deep groove ball bearing is the most commonly used rolling bearing. It is of simple structure and easy to use.
・ This kind of bearing has small friction coefficient and high limit speed.
・ The material of this bearing is equivalent to SUS440C, which has a certain antirust ability.
・ The noise level of this bearing reaches Z1.
 

Product Feature of Ball Bearings

・ The interface radius of the channel located on the inner and outer ring is slightly larger than the radius of the sphere, in arc shape. Mainly can bear radial load.
・ In addition to the open type bearings, there are Ball Bearings with steel dust cover, bearings with contact rubber seal packing and bearings with non-contact rubber seal packing, or bearings with stop ring on the outer diameter of outer ring.
・ Ball bearings with dust cover or seal packing are sealed with proper amount of high-quality grease. Deep groove ball bearings generally adopt steel plate stamped cage, which has low friction torque and accuracy grade of 0.

Precautions for Using Ball Bearings

When the precision of the shaft and Ball Bearings housing is poor, the ball bearings 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 inclination of the inner and outer rings. At this time, besides the bearing 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
Bearing heater		Proper installation of the Ball Bearings heater can guarantee a long life of the Ball Bearings.
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 not need 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
Bearing puller		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 bearing 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 be placed 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: What is the noise level of this kind of products?
Answer: The noise level of this kind of products reaches Z1 standard.
