Product Description
SKF NA 4910.2RS is a high-quality cylindrical roller bearing featuring a 50 mm inside diameter, 72 mm outside diameter, and 23 mm race width. It is engineered to support heavy radial loads in rotating mechanical systems with high precision.
This single-row roller bearing includes shielded ends that minimize debris ingress while allowing effective lubrication, significantly extending service intervals. The bearing utilizes a durable sheet metal cage that ensures precise control of the rolling elements, enhancing longevity and reliability.
Constructed from bearing steel, the bearing offers excellent hardness and fatigue resistance, suitable for industrial and manufacturing environments such as conveyor rollers, gearbox supports, idler shafts, pulley assemblies, and industrial motor supports.
The cylindrical bore design facilitates straightforward installation on straight shafts, and the CN internal clearance reduces shaft-end float for precision fitting. Its limiting speed of up to 3400 rpm suits medium to high-speed applications.
The bearing provides a dynamic load rating of 46.5 kN and a static load rating of 69.5 kN. Sheet metal cage construction assures controlled rolling element guidance. Shielded ends protect against contaminants, reducing maintenance requirements.
Single-row roller configuration maintains a compact form factor while supporting substantial loads. Designed for use in industrial machinery, material handling systems, conveyors, and medium-speed gearboxes.
This SKF cylindrical roller bearing NA 4910.2RS is manufactured in Germany, ensuring premium quality standards and reliability. It is ideal for various industrial mechanical, fluid power, and tooling applications requiring robust, precise bearing solutions.
