The 190 mm insulated steel sleeve bearing 6221-6318 features a bore diameter of 90 mm, an outer diameter of 190 mm, and a width of 43 mm. It is a single-row deep groove radial ball bearing with a pressed steel cage, designed for durability and low maintenance. The bearing supports a dynamic load capacity of approximately 143,000 to 151,000 N and a static load capacity around 108,000 N. It operates efficiently at speeds up to 4800 rpm (limiting) and 7500 rpm (reference), with a temperature range from -40 to 100 °C. The bearing has a C3 clearance for optimal performance and reduced noise generation, making it suitable for fans, pumps, and agricultural machinery. Its robust construction ensures long service life under moderate axial loads.
