61801-2RS

61801 - 2RS is a general-purpose single-row deep groove ball bearing. Its core feature is to be a double-sided sealed low-maintenance bearing suitable for small and medium-sized precision equipment. With a compact size of 12mm inner diameter, 21mm outer diameter, and 5mm width, it can easily fit into space-constrained installation scenarios. Its lightweight characteristic does not add additional load to the equipment. This bearing adopts a double-sided contact rubber sealing design. Compared to the single-sided sealed models, it has better protective performance and can firmly lock the pre-filled lubricating grease at the factory, preventing lubrication loss. At the same time, it can effectively prevent dust, water vapor, and other impurities from entering the bearing interior, significantly reducing the wear of the raceways and balls, significantly extending the bearing's service life, and eliminating the need for frequent maintenance. It is usually made of bearing steel or stainless steel, with good structural stability, capable of stably bearing radial loads and bidirectional axial loads. After low-noise and low-vibration optimization, the friction resistance is small, with a maximum rotational speed of up to 20,000 r/min, ensuring smooth operation of the equipment at high speeds. It is suitable for normal working environments ranging from -20°C to 90°C. In some scenarios, it can withstand short-term high temperatures of up to 110°C. It has extremely strong versatility, not only suitable for industrial equipment such as AC welders, cleaning machinery, and binding machines, but also applicable to small precision devices such as robots and RC racing cars. It is compatible with the interchangeability standard of the same specification bearings, and is a high-adaptability basic component that combines practicality and economy in industrial production and small equipment assembly.
