Product Description
SKF 61801-2RS1 is a high-precision single row deep groove ball bearing designed for applications requiring smooth, low-vibration operation. It features a 12 mm inside diameter, 21 mm outside diameter, and 5 mm race width, sealed with nitrile butadiene rubber (NBR) to prevent moisture ingress and lubrication loss. This bearing incorporates sheet metal cages and steel balls to provide durability and corrosion resistance.
The bearing supports radial and axial loads in both directions and is optimized for high speed, with a limiting speed of up to 20,000 rpm. Its construction and materials make it reliable in demanding industrial environments such as food and beverage processing, pharmaceutical manufacturing, automotive assembly, and aerospace industries. The nitrile seals reduce maintenance requirements and extend operational life.
Key specifications include a static load rating of 915 N and a dynamic load rating of 1.74 kN, with internal clearance rated CN (normal clearance). The bearing has a parallel bore type and plain race type design, with a single row configuration for efficient load handling.
Sealed ends prevent contamination and reduce the need for frequent maintenance. Steel balls and race ensure high load capacity and durability. Sheet metal cage maintains structural stability at high speeds. Precision-engineered for use in high-speed machinery.
Temperature operating range from -40°C to +120°C supports diverse industrial applications. Manufactured in Japan adhering to stringent quality controls.
