KOYO Single Row Cylindrical Roller Bearing, Inner Dia 130 mm, Outer Dia 230 mm , Width 40 mm, NU226CM

A KOYO Bore Dia- 130 mm Single Row Cylindrical Roller Bearing NU226CM is a type of roller bearing that consists of a single row of cylindrical rollers arranged in parallel within an outer raceway and an inner raceway. It is designed to provide high radial and moderate axial load-carrying capacity. In a single-row roller bearing, flanges on the inner or outer ring guide the cylindrical rollers. Depending on the design, the inner circle has two integral flanges, while the outer ring may have one or two flanges. These flanges help prevent axial movement of the rollers, ensuring efficient load distribution. The inner and outer rings of the bearing are typically made of high-quality bearing steel, and the cylindrical rollers can also be made from the same material or other suitable materials, depending on the application requirements. Single-row cylindrical roller bearings are known for accommodating high radial loads due to the linear contact between the rollers and the raceways. They suit various applications, including electric motors, gearboxes, pumps, machine tools, and automotive components. These bearings are available in different designs and configurations to meet specific application needs. Some common variants include: N Design: These bearings have two integral flanges on the inner ring and no flanges on the outer ring, allowing for axial displacement of the shaft relative to the housing in both directions. NJ Design: These bearings have two integral flanges on the outer ring and one integral flange on the inner circle, enabling axial displacement in one direction. NU Design: These bearings have two integral flanges on the outer ring and no flanges on the inner circle, providing axial displacement in one direction. NUP Design: These bearings have two integral flanges on the outer ring and one integral flange on the inner circle, allowing for axial displacement in both directions. To meet various performance requirements, single-row cylindrical roller bearings are available in different precision classes, such as standard, P6 (ISO 6), P5 (ISO 5), and higher. Lubrication is crucial for adequately functioning these bearings, and they can be greased or oil lubricated, depending on the application. Overall, single-row cylindrical roller bearings offer reliable performance, high load-carrying capacity, and versatility, making them widely used in numerous industrial applications.
