How to judge the quality of bearings by appearance
Bearings not only in a variety of mechanical equipment has a wide range of use, the effectiveness of the vehicle wheel is also very large, the key or so that it can be all normal operation, so how to distinguish the quality of the bearing from the appearance of the merits of it:

How to improve the reliability of the engine main bearing?
Many engines have bearings in existence. As long as the bearings have common failures, they will stop running and cannot be carried out during work. If you want to improve the reliability of the engine, you must start with the bearings. Let me talk to everyone. Explain in detail the five countermeasures to improve the reliability of engine bearings.
Two installation methods of deep groove ball bearings
Press fit: when the inner hole of the bearing is fit with the shaft and the outer side is loosely fit with the bearing seat hole, the bearing can be pressed on the shaft with a punching machine, and then the shaft equipped with the bearing is installed into the bearing seat hole together. during the press fit period, a soft metal composite assembly sleeve (copper or high carbon steel) is placed on the end surface of the bearing inner hole, the outer side of the bearing is firmly matched with the hole of the bearing seat. The inner hole and the shaft are loosely matched with each other. The bearing can be pressed into the bearing seat hole first, and then the diameter of the installation sleeve specification should be slightly lower than the diameter of the bearing seat hole.
Structure and history of tapered roller bearings
Do you have work or projects that require heavy parts and equipment to complete? You need the right parts to ensure that the work is completed correctly. When looking for bearings that can withstand large radial forces while withstanding large axial forces, you will most likely need tapered roller bearings. Here, we break down the basics and history of tapered roller bearings.
How to remove and install the outer spherical bearing?
The inner ring of the spherical bearing is fixed on the shaft through the eccentric sleeve, and the inner hexagon screw on the eccentric sleeve plays a fastening role. In the maintenance process, many operators do not know how to disassemble such bearings, so it is necessary to introduce the technical points and precautions for disassembly and assembly of outer spherical bearings.
Functional characteristics of tapered roller bearings
The type code of tapered roller bearing is 30000[5], and the tapered roller bearing is a separate bearing. Generally speaking, especially in the size range involved in GB/T307.1-94 "Rolling Bearing Tolerances", the outer ring and inner assembly of tapered roller bearings are 100% interchangeable.
