The SKF 61801-2RS is an ultra-light series (Thin Section) deep groove ball bearing engineered for applications requiring high rigidity and precision within minimal spatial constraints. Featuring a bore diameter of 12 mm, an outer diameter of 21 mm, and a width of just 5 mm, this bearing provides exceptional speed capability and low running torque. The integral -2RS sealing arrangement utilizes low-friction contact rubber seals on both sides, ensuring maximum exclusion of contaminants (dust, moisture) while retaining the factory-prefilled, high-quality lithium-based grease for lifetime lubrication. Built from high-grade bearing steel (52100), the 61801-2RS is optimized for scenarios demanding reliable operation under moderate radial loads and high rotational speeds, typical in instrumentation and precision motors.
Selecting the 61801-2RS guarantees minimized maintenance downtime and maximized operational life, embodying SKF's commitment to industrial reliability. Its compact design makes it an ideal choice for complex assemblies such as medical equipment, robotics, small-scale gearboxes, and drone components where weight reduction and precise alignment are critical. By maintaining high concentricity and stringent quality control, this bearing reduces vibration and noise levels, contributing to the overall efficiency and lifespan of the host machinery. Invest in SKF quality for dependable performance in demanding thin-section applications.
