Timken Cylindrical Roller Bearings Guide
Product Description
The 863RX3445A Timken four-row cylindrical roller bearing consists of inner and outer rings, four rows of cylindrical rollers, and cages. The four-row design provides high radial load capacity, excellent rigidity, and stable load distribution, making it suitable for heavy loads and continuous operation. These bearings are primarily used in rolling mill roll-neck applications, including hot rolling mills, cold rolling mills, and other steel rolling equipment, providing reliable support for work rolls and backup rolls under demanding rolling conditions.
