Installation method of Deep Groove Ball Bearing
2023-05-12
Installation method I of Deep Groove Ball Bearing: press fit: the inner ring of the bearing is tightly matched with the shaft. When the outer ring is loosely matched with the bearing seat hole, press the bearing onto the shaft with a press machine, and then install the shaft and the bearing into the bearing seat hole together. When pressing, pad an assembly sleeve made of soft metal material (copper or soft steel) on the end face of the bearing inner ring. The outer ring of the bearing is tightly matched with the bearing seat hole. When the inner ring is loosely matched with the shaft, The bearing can be pressed into the bearing seat hole first, and the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing ring is tightly matched with the shaft and seat hole, the installation of the inner and outer rings should simultaneously press into the shaft and seat hole. The structure of the assembly sleeve should be able to simultaneously press the end faces of the bearing inner and outer rings.
How to choose the type of bearing

There are also relevant introductions on how to choose the brand and type of bearings, but some common sense about bearings that are more biased, or are often ignored or ignored, often play a very important role in the use of bearings. Learn about it.
Features of spherical plain bearings
2023-05-12
The structure of the spherical plain bearing is simpler than that of the rolling bearing, which is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Joint bearings are generally used for low-speed swinging motion (ie angular motion). Since the sliding surface is spherical, it can also perform tilting motion (ie self-aligning motion) within a certain angle range. When the degree is large, it can still work normally.
Explanation of self-aligning ball bearings
2023-05-12
The bearing is equipped with spherical balls between the inner ring of the two raceways and the outer ring of the spherical surface of the raceway. The outer diameter of the self-aligning functional bearing and the inner diameter of the bearing seat are spherical cooperation, and there is an active self-aligning function between the two, which can compensate for the misalignment of the axes caused by the device error and the deformation of the bottom surface of the device. The material of the cage is steel plate, synthetic resin, etc.
Precautions for the use of deep groove ball bearings
2023-05-12
For deep groove ball bearings, the bearing load is too small during operation, which will cause sliding between the ball and the raceway, which will become the cause of scratches. This is especially true for large deep groove ball bearings with heavy ball and cage weights. In many cases, bearings will corrode. There are many reasons for bearing corrosion. The most common factors in our daily life are the following:
How deep groove ball bearings work
2023-05-12
Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it is only subjected to radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also high.

What are the classifications of tapered roller bearings?
2023-05-12
A single row tapered roller bearing has an outer ring, whose inner ring and a set of tapered rollers are enclosed by a basket shaped cage as an inner ring component. The outer ring can be separated from the inner ring component. According to the ISO tapered roller bearing outline dimension standard, any standard model of tapered roller bearing outer ring or inner ring component should be able to achieve international interchangeability with the same model of outer ring or inner ring component. In addition to complying with ISO492 (GB307) for external dimensions and tolerances of the same model of outer ring, the cone angle and cone diameter of inner ring components must also comply with relevant regulations for interchangeability.
