The Nachi 22210EXW33 spherical roller bearing features a cylindrical bore with dimensions of 50mm inner diameter, 90mm outer diameter, and 23mm width. It includes a W33 lubrication groove and three oil holes for enhanced grease distribution, supporting high load capacity and durability. Designed for self-aligning operation, it accommodates shaft misalignment and axial loads in both directions, making it suitable for heavy-duty applications. The bearing has a standard internal clearance and can operate at temperatures up to 200°C with minimal dimensional changes. Its robust construction ensures reliable performance under radial and axial loads with vibration resistance and extended service life.
