The 190 mm insulated steel sleeve bearing, available in 6221 and 6318 series, is engineered for demanding electrical applications requiring reliable insulation and robust performance. The 6221 model features a 105 mm bore, 190 mm outside diameter, and 36 mm width, while the 6318 offers a 90 mm bore, 190 mm outside diameter, and 43 mm width, both constructed with high-grade insulated steel for enhanced electrical isolation. These bearings are designed to handle significant radial loads, with dynamic load ratings up to 151 kN for the 6318 and 140 kN for the 6221, and static load ratings of 108 kN and 104 kN respectively. They operate efficiently across a wide temperature range, support high rotational speeds, and are ideal for use in motors, generators, and other electrical machinery where electrical insulation and mechanical durability are critical. The insulated sleeve design minimizes electrical current passage, reducing the risk of bearing damage and improving equipment longevity.
