Plus: sf - 2 boundary lubrication timken bearing acidic poly with formaldehyde in the assembly process, with high wear resistance, Timken bearing surface of the storage pit regularly scheduled, full of grease, especially the high-load low-speed rotary motion, the swing movement, often set a negative, is not easy to form the web site of the opening and closing of fluid lubrication, boundary lubrication conditions, without refueling and maintenance of long-term use, in the refueling process can be extended timken bearing life can be more than is currently available for metallurgical machinery, mining machinery, irrigation machinery, auto parts, engineering machinery, agricultural machinery.
Oil-free self-lubricating timken bearings: This product is a steel plate as the substrate, intermediate layer of sintered spherical bronze powder, surface rolled the mixture of Teflon [ptfe] and lead. It has a small coefficient of friction, wear and corrosion resistance. Oil-free self-lubricating characteristics, long life, use it to reduce costs, reduce noise, prevent sticking, sliding. It is widely used in various machines, such as the sliding parts of printing presses, textile machinery, pallet trucks, tobacco machinery, pharmaceutical machinery, medical, micro motor, automobile, motorcycle.
Metal based solid lubrication timken bearing inlaid metal timken bearing characteristics and functions of the new self-lubricating timken bearing lubrication timken bearing the load of the metal matrix, a specially formulated solid lubricants lubricants. It has a high carrying capacity, impact resistance, high temperature, self-lubricating ability and other characteristics.
Traditional oil-bearing timken bearing: the noisy sound, the advantages of self-lubrication, oil has become the new darling of the computer's CPU fan timken bearings, the market demand; In addition, as people become more Cao Yin, oily requirements of everyday household appliances   The application is expanding.
Timken bearing on the material of the basic requirements of the work to a large extent depends on the performance of the timken bearing. Select whether you want to create a timken bearing material, its performance and life will have a significant impact. Under normal circumstances, the Timken bearing spalling fatigue alternating stress the destruction of the main form, as well as precision timken bearing wear due to friction loss. In addition, cracks, dents, rust and other irregular timken bearing the causes of damage. Timken bearings should have a high resistance to plastic deformation, reduce friction and wear, a good rotation accuracy, good dimensional accuracy and stability, long-term contact fatigue life. Much of the material and heat treatment the properties of joint decision.
Fatigue failure is one of the forms of timken bearing surface failure, failure of the metal in the long-term effect of the alternating load, mainly as the fatigue crack initiation, expansion and fracture process. Cracks in two ways:
First: from the surface in in timken Rolling the contact process, the role due to external loads caused by cyclical changes in the work surface contact stress at the surface of the plastic deformation and strain hardening, and finally to tiny cracks in the surface of the work by to the inside surface development, the formation in the crack between the two surfaces, the lubricant wedged into the crack wall by open force the crack to move forward;
: Crack from the surface, that is repeated under the action of the surface contact stress, the crack was first produced in a certain depth from the contact surface, and along with the surface at an angle to the direction of development to achieve a certain depth from the surface and beyond to the surface up, and finally the formation of pitting spalling, left over the next Ma Hang on the contact surface.
Crack from the surface or from the surface, these two cases is an objective reality (part After carburization, the surface hardening heat treatment, if there is uneven hardness, inhomogeneity, and adverse internal stress in the contact stress under the action of the crack is generally generated from the subsurface. hand, if the poor quality of the part surface finish, the existence of defects (oxidation, decarburization), friction or poor lubrication, the crack from the surface.
