We put forth for clients optimum quality rolling and plain bearings for rotary motion. The bearings help elements roll or slide by producing forces between the parts movable relative to each other. Rolling bearings: the rolling bearing consist two bearing rings with integral raceways and the subject is attached between the rings and roll on the raceways. The subject rolling elements are supported by a cage to maintain uniform distance from each other and preventing collision between the two. Balls, cylindrical rollers, needle rollers, tapered rollers or barrel rollers are most common rolling elements. The cage ensures that the rolling element axis is positioned correctly in case of roller bearings and ribless spherical roller bearings. The cage holds the rolling elements together and gives easier fitting of the bearings, where bearings can be dismantled. However, rolling bearings with a full complement of balls, cylindrical rollers or needle rollers are used in some applications. These are offered in open version or with seals on one or both sides. Among most commonly used seals are gap seals and lip seals. the cage is usually made of steel, however brass cages are used for some applications. Besides, thermoplastic cages are also widely used made using polyamide reinforced by glass fiber. hardened chromium steel and case hardening steel are commonly used to manufacture rings and rolling elements. Additionally, temperature-resistant andor corrosion-resistant steels, plastic, ceramics or other materials are used for extreme operating conditions bearings that can sustain – load, speed, temperature, corrosion. features: •roller bearing design •consideration of each factors •attention to load, speed and influences such as temperature, lubrication, vibrations, fitting and maintenance •bore diameter defined by the design of the adjacent construction •support combined loads, e.g. Deep groove ball bearings, angular contact ball bearings, tapered roller bearings or spherical roller bearings •cylindrical roller bearings n, nu, most needle roller bearings, drawn cup needle roller bearings and needle roller and cage assemblies can only support radial loads. •axial spherical roller bearings and single direction axial angular contact ball bearings that support combined axial and radial loads. applications: •in case of availability of radial space, bearings with a low cross-sectional height are selected such as needle roller and cage assemblies, needle roller bearings with or without an inner ring, deep groove ball bearings and spherical roller bearings of certain series). •in case of availability of axial space available, bearings series including single row cylindrical roller bearings, deep groove ball bearings or angular contact ball bearings are suitable for radial and combined loads •for axial loads, axial needle roller and cage assemblies, axial needle roller bearings or axial deep groove ball bearings.
