Application field

POM lubricated bearing: acid polymethylaldehyde with high wear resistance. It is necessary to assemble with oil storage pit when the bearing surface is arranged regularly
With grease, especially suitable for high load under the low speed of rotation, swing movement and often under load negative, opening and closing and less prone to forming fluid lubrication parts, under the condition of boundary lubrication, can use for a long time without refueling and maintenance, and in the process of gas can be used to more prolong the service life of bearing, currently applicable to the metallurgical machinery, mining machinery, hydraulic machinery, auto parts, construction machinery, agricultural machinery, etc.
Oil-free self-lubricating bearing: this product is a mixture of steel plate, sintered spherical bronze powder in the middle layer, rolled ptfe and lead in the surface layer.It has the characteristics of low friction coefficient, wear-resisting and corrosion-resistant, oil-free self-lubrication and long service life, which can reduce cost, reduce noise, prevent from sticking and sliding.It is widely used in sliding parts of all kinds of machinery, such as printing press, textile machine, hydraulic truck, tobacco machine, medical machinery, fitness apparatus, micro-motor, automobile, motorcycle, etc.
Metal base inlaid solid self-lubricated bearing: it is a new lubricated bearing with both the characteristics of metal bearing and self-lubricated bearing. It is loaded by the metal matrix and lubricated by the special formulation of solid lubricated material.It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubrication ability.Traditional oil-bearing: because of its advantages of low noise and self-lubrication, oil-bearing has become the new favorite of computer CPU fan bearing, and the market demand is large.In addition, with the increasing demand for noise
balance shaft sleeve, brake pedal assembly pliers, turned to the king pin bushings and truck tail plate collar, truck, crane, vehicle crane, forest machinery, packaging machinery, construction machinery, hydraulic motor, agricultural machinery, mining machinery, metallurgical machinery, hydraulic machinery, automobile, steel rolling industries, etc.the application of oil-bearing in household appliances is expanding.

The basic requirements of bearing materials depend largely on the working performance of the bearing.The selection of suitable materials for rolling bearings will have a great impact on their service performance and life.Generally speaking, the main failure modes of rolling bearing are fatigue spalling under the action of alternating stress and loss of bearing precision due to friction and wear.In addition, there are cracks, indentation, corrosion and other causes of abnormal damage to the bearing.Therefore, rolling bearings should have high resistance to plastic deformation, less friction and wear, good rotation accuracy, good dimensional accuracy and stability, and long contact fatigue life.And many of these properties are determined by materials and heat treatment processes.

Chemical properties


-2 Ysurface polymer chemical corrosion resistance, so its corrosion resistance mainly depends on the steel back of plating and appearance. The steel back of tin or copper plated surface, can effectively prevent atmospheric corrosion; If you work in the corrosive medium, the steel back can be galvanized, etc.

 

Wear-resisting performance

 

Under the condition of grease lubrication wear characteristics of the diagram below: it "running-in wear rate is small; By line visible in this picture, when assembling the tu oil consumption to a certain extent, the wear rate increased gradually, as shown in dotted line 1; If before the wear rate rise again come on, its wear rate remained stable; When refueling interval of time, the service life of the material can be greatly extended. It is time to come on interval depends on the cumulative amount of wear and tear. Grease lubrication: when the environment temperature is below 80 ℃, it is recommended to use lithium soap base grease; The environment temperature is higher than80 ℃, it is recommended to use silicone grease; Not recommended with EP additives of oils.

The main factors influencing the life span


1) the influence of PV valuePV value is to determine the wear life of - 1 effective index. If required longevity, PV value must be reduced.
2) the influence of ambient temperatureThe higher the temperature,  - 2 y the shorter service life.
3) dual effectsDual USES alloy steel or hard chromium plated shaft, surface roughness Ra - 0.4-0.63 range,  - 2 y bearing service life can be improved significantly.In addition to standard products show in the catalogue, you can also provide non-standard products according to customer's requirement or order.
