M272647DW/M272610/M272610D Four‑Row Tapered Roller Bearing 482.6x647.7x417.512mm Heavy Load Rolling Mill Bearing

M272647DW/M272610/M272610D is a heavy-duty four-row TQO type tapered roller bearing designed for ultra-heavy load industrial working conditions. Adopting high-strength GCr15 bearing steel and optimized four-row roller arrangement, it features ultra-high radial and bidirectional axial load capacity, excellent shock resistance and structural stability. The open structure supports high-efficiency oil circulation lubrication, effectively reducing operating heat and wear. This large-size industrial bearing is widely applied in rolling mills, metallurgical equipment and heavy mining machinery, maintaining stable and long-lasting operation under harsh continuous working environments.
