About Koyo HK2216 Needle Roller Bearingd Drawn
This Koyo caged drawn cup needle roller bearing has a steel cage and is suitable for applications with high dynamic loads. It has a smaller cross-section than a machined needle roller bearing for use in restricted mounting spaces. The steel cage provides guidance and even spacing of the rollers for reduced friction, vibration, and noise when operated at high speeds. 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 bearing 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 18.1Boundary dimensions, symbols and nomenclature, tolerances, and mounting practicesDeutsches Institut für Normung DIN 618Boundary dimensions and tolerancesInternational Organization for Standardization ISO 3245Roller 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
