- This Koyo heavy duty radial needle roller bearing has a steel cage and seals on both ends, and is suitable for applications with high dynamic and static loads. It has a reduced cross-section (without an inner ring) for use in restricted mounting spaces, and the thick, one-piece outer ring has integral end flanges to provide axial guidance for the cage and rollers. The cage provides guidance and even spacing of the rollers for reduced friction, vibration, and noise when operated at high speeds, and it is made of hardened steel for greater strength, rigidity, and heat resistance than nylon cages. The outer ring has a lubrication groove and an oil hole for applying lubrication in place, and there are lip contact seals at both ends to help retain lubricants and exclude dirt and moisture. 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.
