61803-2RS

61803 - 2RS is a single-row deep groove ball bearing with non-contact rubber seals on both sides. Its core function is to serve as a universal transmission component for high-sealing and low-maintenance applications in small precision equipment. It is specifically designed for scenarios with limited space, high requirements for dust and slight moisture prevention, and the pursuit of long-term stable operation. It features a compact size of 17mm inner diameter, 26mm outer diameter, and 5mm width. It can flexibly adapt to the narrow installation spaces of various small devices. The design of the double-sided rubber seals not only firmly blocks dust, debris, and other impurities from entering the inner raceway to prevent wear but also effectively retains the pre-filled lubricating grease during production. Combined with the high-carbon chromium bearing steel material used in the bearing itself, it ensures good wear resistance and fatigue resistance, while achieving the advantage of reduced lubrication replenishment frequency for low maintenance. This bearing can stably withstand radial loads and handle small axial loads in both directions. It is suitable for normal working environments ranging from -30°C to 120°C. In grease lubrication mode, it has ideal rotational performance. For some specifications, the limit rotational speed under grease lubrication can reach 24,000 r/min. Its standard size specifications and good interchangeability make procurement and replacement more convenient. It is widely applicable in scenarios such as small industrial motors, power tools, miniature pumps, textile equipment, household appliances, and small automated instruments. With its compact structure, reliable sealing performance, and stable transmission performance, it becomes a core component for the transmission of small equipment that balances practicality and economy.
