The 170 mm cast iron sleeve bearing designed for use with bearing numbers 6022, 6219, and 6316 features an approximate outer diameter of 177 mm with a tolerance of ±0.05 mm and a sleeve length of 80 mm. This oversized steel sleeve bearing provides robust support and precise fitment for deep groove ball bearings with a 110 mm bore, 170 mm outer diameter, and 28 mm width, such as the 6022 model. These bearings typically have dynamic load ratings around 85.2 kN, static load ratings near 73.5 kN, and operate at speeds up to 8000 rpm, making the sleeve ideal for heavy machinery and industrial applications requiring durability and stability.
