INA Bearing rings and rolling bodies, side repeatedly withstand the high contact pressure, side accompanying the sliding rolling contact. Cage, side with the rings and rolling bodies on both sides, or a party to the sliding contact side of the tension and compression forces. Therefore, the camshaft bearing rings, rolling element and cage materials, performance, and the main requirements are as follows.
1 hot bearing installation method
Heating of the oil bath bearings, this method may contaminate the bearings, causing premature bearing damage. Induction heating is the most common means of heating bearings, this is because of its controllability, high efficiency and security. INA Bearing manufacturers to determine the induction heater for bearing applications development standards. Cam induction heater has many features to help prevent damage to the bearings in the heating process.
2, bearing cold-install
Under normal circumstances, the small and medium-sized bearing most of the cold-install. Traditionally, INA bearings are installed with a hammer and a section of old pipe. This approach can lead to external forces passed through rolling elements, and damage to the raceway. Cam bearing installation tool to external forces imposed on the press fit bearing ring, helps prevent bearing damage.
3, bearing hydraulic technology installed
The bearing is a pioneer in the use of hydraulic technology in the installation of the INA Bearing these technologies including fuel injection method and drive tight installation method. These methods can help to simplify the bearing arrangement, helps correct and easy installation of bearings. Cam has also developed a number of tools and equipment for bearing hydraulic technology installed, the hydraulic technology implemented.
Further need for impact-resistant case, as the INA bearing material chrome steel, chrome molybdenum steel, nickel-chromium-molybdenum steel, the infiltration of carbon quenching a hardened layer of steel from the surface to the appropriate depth. Hardening depth, meticulous organization, appropriate hardness of the surface and core hardness of the infiltration of carbon bearings, camshaft bearing than bearing steel with excellent impact resistance, chemical composition of the infiltration of carbon bearing steel.
The colloidal stability of the INA Bearing Grease is grease to maintain a stable colloidal structure under certain temperature and pressure, to prevent the precipitation of performance of lubricating oil from the grease, which is the sub-oil grease resistance. Usually translated into the amount of oil grease precipitation mass fraction. Colloidal stability of the grease reflects the grease in the long-term storage and the practical application of hours of oil trends, if the colloidal stability of the grease in the heat, is liable to occur under severe pressure, centrifugal force and the role of oil separator, leading to life quickly reduce and thickens the grease dries out, the loss of lubrication.
