24084B Double Row Wide Spherical Roller Bearing Solid Machined Brass Cage 420x620x200mm Mining Cement Heavy Machinery

The 24084B double-row wide-section spherical roller bearing adopts solid machined brass cage and spherical outer raceway structure. Extra-wide width design greatly boosts load capacity, with outstanding self-aligning performance to compensate shaft deflection and installation misalignment. It withstands ultra-heavy radial load and bidirectional axial thrust, widely applied in mining mills, cement kilns, metallurgical rolling equipment and large heavy-duty reducers.

• Extra-wide cross-section design delivers superior ultra-heavy radial load capacity
• Spherical outer raceway provides excellent self-aligning ability, tolerates housing & shaft misalignment
• Solid machined brass cage maintains stable structure under low-speed heavy shock and high temperature
• Optimized crowned symmetrical rollers reduce edge stress, lower friction and heat accumulation
• Supports bidirectional axial force, suitable for equipment with combined radial-axial heavy loads
• Custom options: W33 relubrication structure, C0/C3/C4 clearance grades, P6/P5 precision classes
• Tapered bore 24084BK version available for quick mounting with adapter sleeves
