23140CCK Double Row Spherical Roller Bearing CCK Tapered Bore CC Brass Cage 200x340x112mm Mining Mill Reducer

The 23140CCK double row spherical roller bearing features CC optimized internal structure, solid machined brass cage and K 1:12 tapered inner bore. Spherical outer raceway delivers excellent self-aligning performance to compensate shaft deflection and mounting misalignment. It withstands heavy combined radial and bidirectional axial loads, widely used in mining ball mills, large industrial reducers, cement rotary kilns and heavy metallurgical transmission equipment.
