Double row tapered roller bearings

Double Row Tapered Roller Bearings (TDO Type) 

Double Row Tapered Roller Bearing (TDO Type) can withstand axial and radial combined loads 

at the same time, so it can be used as a fixed end bearing. It is also used as a free end bearing to 

balance the relative movement between the bearing housing and the outer ring of the bearing 

caused by thermal deformation of the shaft.

Double Row Tapered Roller Bearings (TDI Type) 

Double row tapered roller bearings are generally used where there is only axial load or axial load 

greater than radial load. In some cases, spring is used to provide a preload between the bearing 

housing and the back of the bearing outer ring (without the outer ring spacer).

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.
