Product Description

Oilless bearing (SF-1) is a kind of both metal bearing characteristics and bearing characteristics of novel lubrication bearing lubrication system, the load matrix, and the special formula of solid lubricating materials lubrication. It has high bearing capacity, impact resistance, high temperature resistant, self-lubricating ability etc., especially suitable for overloading, low-speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion. Users generally reflect not only fuel-efficient inlaid bearing, energy conservation, and its working life is longer than ordinary sliding bearing. At present the product has been widely used in metallurgical continuous casting machine, steel rolling equipment, mining machinery, shipping, steam turbine, water turbine, injection molding machine and equipment in the production line.


The production process:


Part of product category:


Different sizes and Model Number available

We can also provide OEM service according to your requirement.


There are many kinds and types of bearings,pictures may not be the product figure in fact , If you are interested please contact us, We will go to the warehouse to photograph the actual photos for you and  do our best to meet your requirements.


1. We can change the rubber seal color according to your actual requirements.

2. Customized the marks based on your requirements.
3. Choose the different package to your needs.



Installation Notice

1. Be sure that the mating surface of axis, the axis and shell have bumps, etc.

2. If there is a dust or sand mold is attached on the surface bearing housing.

3. Although it was slight bumps, bumps, etc., if you have to fine sandpaper to remove stone or oil.

4. In order to avoid bruising, during RongZhuang on the surface of the shaft and the shaft shell should apply a small amount of lubricating oil. To install the bearing axis when applying pressure on the inner ring, bearing installed on the bearing shell, to applying pressure to outer ring. Applying pressure to the bearing, be sure to be careful to evenly, vertical force and partial play will make bearing were injured. Absolutely avoid to slant for this play.

5. Oil-free bearings bearing retainer and applying pressure sealing plate is absolutely not. Use hammer and casing installation method, it is generally commonly used method, because can damage the bearing, so Don't knock directly. Must be as shown in figure, make the socket interface in the middle and tapping into it. Hammer should be light light knocks. On the mechanical structure, inner and outer ring are tight fit, you should use plate, make sure power can also add to pressure in the rings. If only in the inner ring into tension, the force will dielectric ball and pressed into the outer ring, therefore, can cause scars in the orbital plane. To margin big bearing installed on the shaft, in clean oil, bearing heated to 80-80 degrees, the inside diameter expansion to install method, is widely used.

6.The hardness of bearing is reduced due to overheating and, therefore, must not exceed 100 degrees. At this point, the shaft bearing steel wire must be used for hanging, or placed in metal wire, support plate, please do not placed in the bottom of the channel. Bearing to hope temperature (100 degrees), should be immediately removed from the tank, quickly into the shaft, bearing will be along with the temperature drop and shrinkage, sometimes between shoulder and bearing

face, will produce gap, therefore, need to use tools, the bearing axis direction compression.



Clean the bearing will be removed check, use methods such as taking pictures first recorded appearance. In addition, to confess the residual amount of lubricant and lubricant sampling, and then clean the bearing. Examination and distinguish to distinguish can remove the bearings from scratch using, check on the accuracy for the standard, rotating accuracy, internal clearance and collaboration, raceway surface, insist on frame and seal rings etc. About the inspection effect that can be used by bearing or known bearing. Sentenced to standard according to the mechanical function and importance as well as other inspection cycle, etc. If you have the following injury, bearing shall not be applied from scratch, it is necessary to exchange.





SF-2 add boundary lubrication bearing: acidic poly methyl aldehyde, has the very high wear resistance, bearing surface is arranged regularly with oil storage pit must be lubricated with grease, when assembly is particularly suited to high load under the low speed of rotation, swing movement and often under negative load, the 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 bearings: this product is based on steel substrate, the middle layer sintered spherical bronze powder, surface rolling polytetrafluoroethylene (ptfe) and the mixture made of lead. It has a small friction coefficient, wear resistance, corrosion resistance. Oilless self-lubrication and long service life characteristics, use it can reduce cost, reduce noise, to prevent sticking, slippery. It is widely used in various mechanical sliding parts, such as printing presses, textile machines, hydraulic carrier, tobacco machine, medical machinery, machines and micro-motor, automobile, motorcycle, etc.

Base metal Mosaic solid self-lubricating bearing, is a combined metal bearing characteristics and self-lubricating bearing characteristics of novel lubricated bearing, by load matrix, and the special formula of solid lubricating materials lubrication. It has high bearing capacity, impact resistance, high temperature resistant, self-lubricating ability, etc. Traditional oil bearing: because of the travel the advantages of low noise, self-lubricating, oil bearing has become the latest must-haves in the computer CPU fan bearing, the market demand is big; In addition, as people more and more high to the requirement of noise, oil bearing application in daily household appliances are also expanding.

The basic requirement of bearing on the material depends largely on the bearing performance. Choose rolling bearing materials is more appropriate are made, has a great influence on the its using performance and life will be. Under normal circumstances, the rolling bearing is the main damage form under the action of alternating stress fatigue spalling, and make bearing precision loss due to friction and wear. In addition, there is crack, indentation, corrosion causes such as bearing abnormal damage. Rolling bearing, therefore, should have high ability to resist plastic deformation, less friction and wear, good rotation accuracy, good dimensional accuracy and stability, as well as the long contact fatigue life. And many of these performance is determined by material and heat treatment process together.
