Bearings are components that fix and reduce the friction coefficient of load during mechanical transmission. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. According to the different friction properties of moving elements, bearings can be divided into two types: rolling bearings and sliding bearings.
In order to ensure the smooth and reliable operation of the bearing, most of the bearings are lubricated with lubricating oil. The purpose is to reduce the internal friction and wear of the bearing and prevent burning and sticking: prolong the fatigue life of the bearing; discharge friction heat or heat from the outside. ; At the same time, the oil film also has a certain ability to absorb vibration. However, one of the biggest disadvantages of adding lubricating oil is that good sealing performance is required, otherwise leakage will occur, and some equipment with special requirements does not allow leakage of lubricating oil, so people use other lubricating materials to replace lubricating oil, invented Oil-free bearings not only have the advantages of lubricated bearings, but also eliminate environmental pollution caused by leakage.

Metal-Polymer Bronze Backed PTFE Plain Bearing

The material is developed according to the special conditions of the reciprocating movement of the shock absorber and the large lateral force. It has a low friction coefficient and good wear resistance and can be used in semi-dry conditions. Products are mainly used in automobile shock absorbers, motorcycle shock absorbers, hydraulic cylinders, etc. Because it does not contain lead, it makes the lubrication conditions cleaner and meets environmental protection requirements.

Choosing The Plain Bushing Structure

The hydraulic bearing is still essentially an oil-impregnated bearing. But this kind of improved, the life is greatly extended than ordinary oil-sealed bearings, and inherits the advantages of oil-impregnated bearings – low operating noise . The working noise of the hydraulic bearing is significantly reduced, and the service life is also very long, which can reach 40,000 hours! Hydraulic bearings, because this product has the characteristics of high precision, high speed, high rigidity, etc., and can customize exclusive products for customers according to the customer’s use environment and precision requirements. This greatly improves the processing efficiency of customers and saves processing costs. Hydraulic bearingHydraulic bearing, a material designed on the basis of oil-free bearing combined with the working principle of oil cylinder and shock absorber, is more obvious under oil-free conditions. In addition to the advantages of hydraulic bearing, this product is especially suitable for frequent reciprocation. Large lateral force occasions. Its performance is similar to that of foreign DP4, and it is suitable for automobile, motorcycle shock absorbers and various hydraulic cylinders and other fields.
