Koyo K4X7X7TN Needle Roller Bearing and Roller, Open, Polyamide Nylon Cage, Metric, 4mm ID, 7mm OD, 7mm Width: Industrial & Scientific. Koyo K4X7X7TN Needle Roller Bearing and Roller, Open, Polyamide Nylon Cage, Metric, 4mm ID, 7mm OD, 7mm Width: Industrial & Scientific. Radial needle roller and cage assembly for applications with high dynamic loads 。 High axial load capacity with reduced cross-section for use in restricted spaces 。 Reinforced polyamide nylon cage guides and evenly spaces rollers for reduced friction, vibration, and noise 。 Through-hardened, high-carbon chromium steel rollers for heat tolerance and durability under heavy loads 。 Meets standards ANSI/ABMA 18.1 , DIN 5405-1, and ISO 3030 for quality assurance 。 This Koyo radial needle roller and cage assembly has a nylon cage and is suitable for applications with high dynamic loads. It has a smaller cross-section than a standard needle roller bearing for use in restricted mounting spaces. The molded glass fiber reinforced polymer cage provides guidance and even spacing of the rollers for minimum vibration and noise at high speeds, and allows the assembly to operate at temperatures up to 24 degrees F (120 degrees C). The needle rollers are made of through-hardened, high-carbon chromium steel for durability and heat tolerance, and have contoured ends to optimize the distribution of contact stress. This radial needle roller and cage assembly is used in various applications, such as automotive and truck transmissions, agricultural and construction equipment, pumps and compressors, and two-cycle engines, among others.。SpecificationsIdentification code, boundary dimensions, symbols and nomenclature, tolerances, and mounting practicesAmerican National Standards Institute/American Bearing Manufacturers Association ANSI/ABMA 1.1Boundary dimensions, symbols and nomenclature, material, tolerances, raceway design, and mounting practicesDeutsches Institut für Normung DIN 55-1Boundary dimensions and tolerancesInternational Organization for Standardization ISO 3030。Roller bearings use rolling elements to maintain a separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. Roller bearings can be open on both ends (a shaft can pass through) or open on one end and closed on the other. An open end can be sealed or shielded to protect the bearing from solid contaminants and moisture that could reduce its lifespan. If an end is sealed, the sealing component is an elastomer lip that contacts the shaft. If it is shielded, the shielding is a non-contact lip, usually made of metal. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.。 USA manufactures , bearing assemblies, and needle rollers for automotive and industrial applications. The company, founded in 2009, is headquartered in Canton, OH, and meets International Organization for Standardization (ISO) standards 101 and TS 16949 for quality assurance.。 。 。 。
