NSK bearing rings and rolling, repeated high contact pressure, accompanied by sliding of rolling contact. Cage, with rings and rolling elements on both sides, or one side sliding contact, side of tensile and compression forces. Therefore, reversed heart ball bearing rings, rolling elements and cage materials, performance, the main requirements are as follows.
Heat 1, bearing installation methods
Heated oil bath bearing, which may contaminate the bearing, causing premature failure of bearings. Induction heating is the most commonly used means of heating the bearing, this is because its control, high efficiency and safety. NSK bearings manufacturers determine the induction heater for bearing applications research and development standards. Self-aligning ball bearings induction heater has many functions and helps prevent damaged bearings during the heating process.
2, bearing cooling installation
Under normal circumstances most of medium and small bearing cooling installation. Traditionally, NSK bearings are installed with a hammer and a section of the old tubing. This approach can result in force after passing rolling elements, so as to damage the Raceway. Self-aligning ball bearing installation tool will be the external force imposed on the press fit bearing rings, helps to prevent bearing damage.
3, bearing installation of hydraulic technology
Bearings are used in the NSK bearing install hydraulic technologies, a pioneer in these technologies, including the oil law, and tight installation of displacement. These methods can help simplify bearing arrangement, help correct and simple way to install the bearing. NSK bearing company also developed a number of tools and equipment for bearing installation of hydraulic technology, make these hydraulic technology into practice.
Need more shock-resistant cases, as NSK bearing materials using chromium steel, chromium-molybdenum steel, Nickel-chromium-molybdenum, permeability of carbon steel quenched, keeping to the right there is a hardened layer depth from the surface. Organizations with the appropriate hardening depth, close and suitable hardness of surface and core hardness of permeability of carbon bearing, self-aligning ball bearings using bearing steel with excellent impact resistance, permeability and chemical composition of carbon bearing steels in General.
NSK bearing grease refers to the colloidal stability of lubricating greases at a certain temperature and pressure are kept stable colloidal structure, preventing precipitation of lubricating oil from lubricating grease performance, that is, ability to resist oil separation of lubricating greases. Usually precipitated oil grease quantity into quality score instead. Reflects the colloidal stability of lubricating grease in grease in long term storage trends and practical application of the night oil, grease the colloidal stability of difference are easily subjected to heat, pressure, centrifugal force following major oil, resulting in lower life quickly, thicken and grease dries, loss of lubrication.
