NA6908

INA radial needle roller bearing has a steel cage and an oil hole, and is suitable for applications with high dynamic and static loads. It has an inner ring to provide a hardened and ground roller raceway for applications in which the shaft cannot be used as a raceway. 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 the outer ring has a lubrication groove and an oil hole for applying lubrication in place. This radial needle roller bearing meets Deutsches Institut für Normung standard DIN 617 and International Organization for Standardization standard ISO 1206 for quality assurance.
