1. The effect of temperature on lubrication Lubricating oil is the lubrication method of most SKF bearings. The characteristics of the lubricating oil determine its applicable temperature range. Whether it is grease lubrication or oil lubrication, its lubrication performance is affected by temperature changes, mainly as follows:...

1. FAG deep groove ball bearing seal structure analysis FAG deep groove ball bearings have a variety of sealing structures. According to the different sealing materials, they are mainly divided into two types: rubber sealing ring and dust cover (standard iron cover): according to the different sealing arrangements, they can be d...

KOYO bearings need to add grease at any time to replace the grease that has deteriorated, exuded and contaminated. Due to the ever-changing operating conditions of KOYO bearings, on-site proprietary technology is required to determine the appropriate grease addition interval from once a day to once a year. There is no grease or ...

1. Bearing type Need to distinguish betwee n point contact (NTN ball bearings) and line contact (NTN needle roller bearings and NTN cylindrical bearings). For NTN ball bearings, the contact area for ball movement is relatively small, and grease with a base oil viscosity of ISO VG 68 to 100 is usually sufficient. NTN bearings wit...

1. Principle of indirect measurement method of axial load In the aero-engine design process, according to the calculation method of the engine rotor axial force, the rotor axial force can be divided into two parts: the axial force of the disc cavity and the axial force of the runner. The axial force of the disc cavity is the sum...

1. Working principle of one-way clutch bearing One-way clutch bearing is a type of bearing, which is characterized by the function of one-way rotation and reverse stop. It is widely used in one-way clutches of washing machines, one-way clutches of automobiles and one-way clutches of electric vehicles. The one-way clutch bearing ...

Split bearings refer to parts designed and produced on the basis of integral bearings through a special process. Split bearings are suitable for many fields, such as: large-scale conveying equipment, co-cast roll supports, elevators and conveyors, paper machinery and other industrial fields. Installation is also very important f...

1. The limit speed of NTN bearing The speed of NTN bearing is mainly limited by the temperature rise caused by the friction heating inside the bearing. When the speed exceeds a certain limit, the bearing will not continue to rotate due to burns. The limit speed of NTN bearing refers to the limit value of the speed at which it ca...

Lubrication plays an important role in the use of TIMKEN bearings. In many cases, the damage of TIMKEN bearings is caused by poor lubrication. According to statistics, about 40% of TIMKEN bearing damages are related to poor lubrication. In order to get a good lubrication method for the bearing, Eric Bearing Limited analyzed the ...
