  The Most Common Causes of Bearing Failure and the Importance of Bearing Lubrication

  Bearing grease is widely used in the industrial production of rolling bearings, and bearings are the basic parts of mechanical equipment. In the operation of the rolling bearing, the rolling friction will cause the heating and wear of the bearing, reducing friction and damage, so the operation of the rolling bearing requires lubrication. Generally, under special conditions of low speed and heavy load, sliding bearings requir...

  Common Fault Analysis And Elimination Method of Needle Roller Bearing

  Needle roller bearings are roller bearings with cylindrical rollers, which often appear in automobiles or motorcycles in our daily lives. The roller is elongated relative to its diameter. This kind of roller is called a needle roller. Despite the small cross-section of the bearing, the bearing still has a high load-carrying capacity. Needle roller bearings are equipped with long and thin rollers, so the radial structure ...

  How To Judge ZZ Bearing Damage

  When using rolling bearings, due to their own quality and external conditions, their load-bearing capacity, rotation accuracy and anti-friction performance will change. When the performance index of the bearing is lower than the use requirement and cannot work normally, it is called bearing damage or failure. Once the bearing is damaged or other accidents occur, the mechanical equipment will stop rotating and its function wi...

  The Knowledge of Spherical Roller Bearings

  Definition of spherical roller bearings The rolling elements are spherical bearings with spherical rollers. Spherical roller bearings have two rows of rollers, which mainly bear radial loads and can also withstand axial loads in either direction. There is a universal spherical raceway in the outer ring. The two inner ring raceways are inclined at an angle to the bearing center. The bearing is self-centering, so it i...

  The Four Stages of Rolling Bearing Failure

  The development of rolling bearing is not a linear process, but an exponential process. In different degradation stages, fault information appears in different frequency band ranges, so different fault detection methods should be adopted. At present, it is generally believed in the industry that the degradation of rolling bearings can be divided into four stages. Stage 1 — Initial bearing failure Bearing a...

  How to Use Tapered Roller Bearings

  Tapered roller bearings mainly bear radial and axial combined loads. Bearing load capacity depends on the raceway angle of the outer ring, the greater the angle, the greater the load capacity. This type of bearing is a separate bearing. It is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single-row tapered roller b...

  Methods To Prolong The Service Life Of ZZ Bearings

  ZZ bearings are a kind of central nervous system in dull operation. They work day and night, and keep advancing, like the legendary perpetual motion machine. Perpetual motion machines do not exist at all. A thing always has its life cycle and its own life span.
