Tapered roller bearings

Tapered roller bearings are mainly used to bear radial and axial combined loads, mainly radial load; while tapered roller thrust bearings with large taper angle can be used to bear radial and axial combined loads, mainly axial loads.

Tapered roller bearing is is of separate type, and its inner ring (including tapered roller and cage) and outer ring can be installed separately. In the process of installation and use, the radial and axial clearance of the bearing can be adjusted, or pre-interference installation can be done. 

Bearings with this type include single row tapered roller bearings, double row tapered roller bearings and four row tapered roller bearings, used for a variety of industrial applications.

Main structural forms of tapered roller bearings:

1. Single row tapered roller bearing

Single row tapered roller bearing can limit the axial displacement of the shaft or shell in one direction and bear the axial load in one direction. Additional axial force is generated under the action of radial load. Therefore, in the two supports of the shaft, the end faces of bearing outer ring and bearing inner ring are oppositely mounted. If used alone, the applied axial force must be greater than the additional axial force. The 313 series tapered roller bearings have large contact angles (27°~ 30°) and can withstand large axial loads. The contact angle of tapered roller bearings in other series is between 10°and 18°.

2. Double row tapered roller bearing

Double row tapered roller bearing has a pair of raceway outer ring and two inner rings, and a middle spacer between the two inner rings. The thickness of the spacer can be adjusted to adjust the bearing clearance. Double row tapered roller bearing can bear the bidirectional axial load while bearing the radial load. It can limit the bidirectional axial displacement of the shaft or shell within the axial clearance range of the bearing.

3. Four row tapered roller bearings

Four row tapered roller bearings adopt two double raceway inner rings, one double raceway outer ring and two single raceway outer rings, and there are spacers between inner ring and outer ring for adjusting clearance. It has similar performance with double row bearing: large radial load and low limit speed. Four row tapered roller bearings are mainly used for heavy machinery, such as rolling mill.

MOTORCYCLE

Each motorcycle is usually equipped with 20 to 30 bearings. These bearings are used for important rotating parts such as engines, transmissions, and wheels to support driving, and are responsible for reducing friction and driving the engine power to the wheels. Therefore, the performance required for motorcycle bearings is to achieve smooth rotation through low friction, low vibration and high durability. These performance affect the fuel consumption and safety that are closely related to our life. ZYS always pays attention to these details and strives to develop bearing and optimize the bearing design to improve the quality of life and protect the global environment.

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.
