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. BR202820 Bearing · Needle Roller Bearing · Dimensions: 1-1/4" x 1-3/4" x 1-1/4" inch · ID (inner diameter)/Bore: 1-1/4" inch · OD (outer diameter): 1-3/8" inch... 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. Koyo Bearings USA manufactures needle roller bearings, bearing assemblies, and needle rollers for automotive and industrial applications. 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. Roller bearings can be open on both ends (a shaft can pass through) or open on one end and closed on the other. Heavy duty, single row, radial needle roller bearing for applications with high dynamic and static loads Specifications Identification code, boundary dimensions, bearing tolerances, and fitting and mounting practiceAmerican National Standards Institute/American Bearing Manufacturers Association ANSI/ABMA 18.2Standard specification for needle roller bearings having thick outer rings, with rollers and cageASTM International ASTM F2246Military standard for needle roller bearings having thick outer rings, with rollers and cageMilitary Standard MS51961Roller 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. An open end can be sealed or shielded to protect the bearing from solid contaminants and moisture that could reduce its lifespan. 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. This Koyo heavy duty, single row, radial needle roller bearing has a steel cage and an oil hole in the outer ring, and is suitable for applications with high dynamic and static loads.
