TIMKEN TQO Series Tapered Roller Bearing

TQO Four-Row Tapered Roller Bearing is an extreme heavy-duty special bearing of TIMKEN. Adopting a parallel four-row roller structure, it achieves top-level radial load capacity, capable of bearing super large impact load and continuous heavy load, and supports thermal expansion floating compensation for equipment. With large overall size and stable structure, it is specially designed for low-speed and ultra-heavy harsh working conditions, serving as the core accessory of metallurgical rolling mills, mainly used for work rolls and backup rolls of steel and non-ferrous metal rolling mills.
