ZYS Heavy load Double-Row Spherical Roller Bearing 23168 CA/W33 Auto Bearing for Vibrating Screen 

Application of spherical roller bearing:

Continuous Casting Machines
Mechanical Fans and Blowers
Gearbox and Pumps 
Wind Turbines
Material Handling 
Marine Propulsion and Offshore Drilling
Mining and Construction Equipment
Pulp and Paper Processing Equipment

Spherical roller bearings have two rows of rollers that are mainly used for withstanding radial loads and also axial loads in either direction. Self-aligning roller bearings have high radial load capacity, especially suitable for heavy load or vibration load, but can not withstand the axial load. Spherical roller thrust bearings have good self-aligning properties and can compensate for the coaxiality error. 

About ZYS

Luoyang Bearing Research Institute Co., Ltd. is a high tech enterprise specializing in the development of "high rank, precise, advanced, unique, 
special" bearing products for the key units in various fields of national economic construction. Its predecessor, Luoyang Bearing Research Institute, 
was established in 1958. It is the only state level comprehensive research institute in China's bearing industry. In 1999, it entered China National 
Machinery Industry Group Co., Ltd. and transformed into a science and technology enterprise.
We focus on developing high performance bearing products for key units of national economic construction. We perform batch production of various 
high rank bearing products and components with inner diameter of 0.6mm to outer diameter of 6.8m. We are mainly engaged in the research, 
development, production and sales of precision bearing, special bearing, high speed machine tool spindle, bearing special equipment, bearing 
testing instruments, bearing testing machine and bearing special materials, which are widely used in the fields of aerospace, machine tools, wind 
power generation, mine metallurgy, petrochemical, medical equipment, automobiles and rail transit, construction machinery, intelligent 
manufacturing services, etc.
We have total assets of 2.06 billion RMB, own one research and development center, three industrial bases and cover an area of more than 47 hectares. We have advanced bearing manufacturing equipments and world first class testing equipments and have solid strength in manufacturing, 
measuring and testing of bearing and related components with high precision and high reliability. We have more than 380 technical staff of bearing 
related disciplines, thus we maintain a leading position in the aspects of bearing design, basic theoretical research, lubrication technology, metallic 
and non-metallic materials, testing and industry standards.

Many scientific research centers, laboratory and service agencies are set in our company, including National Bearing Quality Supervision and 
Inspection Center, National Bearing Accreditation Laboratory, Industrial (Rolling Bearing) Product Quality Control and Technical Evaluation
