61806-2Z

Model 61806-2Z is a single-row deep groove ball bearing equipped with bilateral metal dust-proof covers (2Z type). Its core positioning is for general transmission components that require comprehensive requirements for dust protection, high rotational speed, and stable operation in narrow installation spaces. It is specially designed for small and medium-sized equipment that need to balance sealing protection and basic operating performance. It retains the compact size of the 61806 series with an inner diameter of 30mm, an outer diameter of 42mm, and a width of 7mm. It is suitable for installation scenarios with limited space. The bearing body is made of GCr15 high-carbon chromium bearing steel, and the bilateral metal dust-proof covers can effectively prevent dust, debris, and other impurities from entering, while reducing internal lubricant leakage, extending the maintenance-free period, and not significantly affecting the high rotational speed performance. This bearing can stably withstand radial loads and small axial loads in both directions, is suitable for normal working environments ranging from -30°C to 120°C, and is pre-filled with lithium-based composite lubricating grease upon factory assembly. The standardized size ensures strong interchangeability, making procurement and replacement convenient. It combines practicality and protection advantages, and is widely used in general machinery, motors, automotive auxiliary components, household appliances, automation equipment, and other scenarios, especially suitable for continuous operation equipment with basic protection requirements in dusty or semi-open installation environments.
