NNC 4928 CV

The NNC 4928 CV Double Row Cylindrical Roller Bearing is a high-capacity and robust solution specifically engineered for applications demanding immense radial load support, particularly at moderate to low speeds. This specialized bearing features an "NNC" design, which typically includes a solid outer ring and an inner ring with two ribs, allowing for crucial axial displacement relative to the axel .
The "CV" suffix is ​​key, denoting a full complement of cylindrical rollers, meaning the bearing lacks a cage and is packed with the maximum possible number of rolling elements. This design significantly enhances its static and dynamic radial load-carrying capacity, making it exceptionally rigid and durable under extreme forces. While not suited for very high-speed operations due to the increased friction from roller-to-roller contact, its full complement design ensures unparalleled strength and longevity in heavy-duty scenarios. Commonly found in critical machinery such as heavy industrial gearboxes, rolling mill stands, lifting equipment, large electric motors, and cement mills, the NNC 4928 CV provides reliable performance and extended service life where massive radial loads and robust operation are Paramount .
