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.

Q1: What type of bearing is M272647DW/M272610/M272610D?
A1: It is a TQO structure four-row tapered roller bearing, composed of one inner cone and two outer cups, specially designed for ultra-heavy load industrial equipment.
Q2: What load can this four-row bearing withstand?
A2: It supports super heavy combined radial load and bidirectional axial load, with far higher load capacity than double-row tapered roller bearings.
Q3: What lubrication method is suitable for this bearing?
A3: Both grease lubrication and oil lubrication are available. Circulating oil lubrication is recommended for long-term continuous heavy-duty operation to ensure better heat dissipation.
Q4: What are the main application scenarios of this bearing?
A4: It is mainly used for steel rolling mills, metallurgical machinery, heavy mining equipment, large industrial transmission and other heavy-load mechanical fields.
Q5: Is this bearing suitable for high-speed operation?
A5: It is optimized for low-to-medium speed and ultra-heavy load working conditions, focusing on load resistance and stability rather than ultra-high speed rotation.
