UC211

The UC211 maintenance-free insert ball bearing is an industrial general-purpose self-aligning bearing, suitable for various transmission matching scenarios with low speed and heavy load. Its core specifications are inner diameter 55mm, outer diameter 100mm and width 27mm. The main body of the bearing is made of high carbon chromium bearing steel, equipped with a double-sided sealed protective structure and pre-filled with long-life lithium-based grease, achieving maintenance-free performance throughout the whole life cycle. It can effectively block the intrusion of dust and water vapor and improve the service stability under harsh working conditions. The bearing has a static load capacity of 43.2kN and a dynamic load capacity of 66.5kN, with a limiting speed of 3200r/min. The spherical outer ring design can be flexibly matched with various bearing housings, automatically compensating for installation coaxiality errors, featuring easy installation and reliable operation. It is widely used in industries such as conveying machinery, agricultural machinery, mining machinery, light textile equipment, construction machinery and general motors, and is an optimal accessory for bearing housing transmission.
