Four-row tapered roller bearings

The design principle of the four-row tapered roller bearing is to improve the carrying capacity of the rolling mill bearing as much as possible by optimizing the structure in a limited assembly space.

Four-row tapered roller bearings are generally mounted on the roll neck with clearance fit for easy installation and disassembly. Due to the possible slippage between the inner ring hole and the roll neck, proper lubrication should be maintained on the contact surface to avoid wear. In order to prevent the inner ring end face and the inner spacer end face from sliding and rubbing each other, lubricating oil grooves are formed on both end faces of the inner ring and the inner spacer. There is an oil groove and several oil holes on the middle and outer rings.

METALLURGY AND CONSTRUCTION

There are many kinds of metallurgical equipment, including not only the equipment needed by the raw material factory, but also the equipment needed from the upstream process to the downstream process, such as steelmaking process, steel rolling process and leveling process. These bearings are used under the special conditions of iron powder, water and heat of metallurgical equipment, so they need to meet the requirements of heavy load , vibration shock, from ultra-low speed to high-speed & rapid acceleration and deceleration. "Stable operation and improved production efficiency" can be described as a representative industry in the field of metallurgical equipment. ZYS is not only in bearing design technology, but also in various aspects such as bearing material technology, lubrication technology, and analytical technology.
