The new website has been launched. Welcome new and old customers to consult and cooperate!
Bearing retainer, also known as bearing cage, is one of the main parts of the bearing. Its role is to wrap and isolate the rolling body and move with it, and usually also has the role of guiding the rolling body. The cage is subjected to stresses caused by friction, strain and inertia forces, and also to the chemically corrosive effects of lubricants, additives in lubricants or substances due to their aging, organic solvents or coolants. Therefore, the design and material of the cage are extremely important for its performance and the reliability of the bearing.
Rolling bearings in the process of use due to its own quality and external conditions, its bearing capacity, rotational accuracy and friction reduction performance will change, when the performance index of the bearing is lower than the use of the requirements and can not work properly, there will be machinery and equipment to stop running, the function of damage and other abnormal phenomena. If effective maintenance procedures are taken in bearing mounting and dismounting, lubrication, pollution prevention and personnel training, online inspection and timely troubleshooting, the above failures can be avoided. Bearing mounting and dismounting should pay attention to the use of appropriate tools and methods Bearing mounting is a strict maintenance work, the good or bad mounting, directly affect the accuracy, life and performance of the bearing.
Of course there is lubricant inside the wheel bearings of a car, but it is a low-fluidity grease (yellow dry oil). Of course the wheel bearings of a car can break down, but when they do, they can simply be replaced with new bearings. Relatively speaking, the rolling bearings used in small non-load machinery are maintenance-free for life, which is different from the sliding bearings that are often changed.
Rolling bearings show a strong regularity in their use, and repeatability is very good. Normal high-quality bearings (rolling bearings) in the beginning of use, vibration and noise are relatively small, but the spectrum is somewhat scattered, the amplitude are small, may be due to some defects in the manufacturing process, such as surface burrs, etc..
Rolling bearing is an important mechanical components, a mechanical equipment whether the function can give full play to the bearing smooth can be appropriate, smooth is to ensure the normal operation of the bearing necessary conditions, it is on the progress of bearing bearing bearing capacity and use of life plays an important role. No matter what kind of smooth method is used, smooth in the rolling bearing can play the following kinds of effect.
Suzhou Dongwu Needle Roller Bearing Co., Ltd. is located in Suzhou Industrial Park, adjacent to Wusong River and airport road in the south, national highway 312 and Shanghai Nanjing Expressway in the north, with superior geographical location and convenient transportation.
