MACHINE TOOL

Machine tool is the carrier of advanced manufacturing technology and the basic production means of equipment industry. It is the basic equipment for equipment manufacturing industry, mainly for automobile, military, agricultural machinery, engineering machinery, electric power equipment, railway locomotive, ship and other industries. Machine tool performance plays an increasingly important role in production efficiency and product quality and also has high demand for more reliable and energy efficient components.

VEHICLE

Driven by increasing environmental awareness and stricter emission regulations, the automotive industry is undergoing an unprecedented period of change. Computer technology has been used in the control and monitoring devices of many vehicle systems. New materials for cars, such as light alloys, have been gradually used in mainstream cars, and new technologies allow for further emissions cuts.

RAILWAY

Railway transportation is one of the main ways of transportation. As the main means of railway transportation, train technology is constantly innovating. Freight vehicles with increasing load, locomotive vehicles with increasing traction, or passenger vehicles with increasing running speed are affecting people's way of life.

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.

AGRICULTURE

Agricultural engineering involves a wide range of machinery, equipment and tools, most of which are specially designed and manufactured according to the characteristics of agriculture and the special requirements of various operations, such as soil tillage machinery, planting and fertilization machinery, plant protection machinery, crop harvesting machinery, animal husbandry machinery and agricultural products processing machinery, etc. Another part of agricultural machinery is common to other industries, and can be directly selected according to the characteristics and needs of agriculture, such as agricultural power machinery, water pumps in farmland irrigation and drainage machinery, etc.; or design these machinery into agricultural variants according to the characteristics and needs of agriculture, such as agricultural vehicles, trailers in agricultural transport machinery, stone machinery in farmland construction machinery.

ELECTRIC MOTOR

Motors are used as power sources in all industries. In the development of the electrification of power sources, in order to meet the requirements of environmental protection, low energy loss and high reliability, ZYS continuously developed high-performance bearings with low friction. These bearings are widely used in the rotating part of the motor, which can play a significant role in bearing the load carried by the motor while supporting smooth and quiet rotation.

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.

OIL AND GAS

Oil and gas technology is developing at a very rapid pace, and exploiting deeper oil and gas resources in harsher environments means that the top drives need more power to withstand higherloads.When unforeseen downtime costs are as high as $1 million per day, the reliability of equipment becomes particularly important, and the reliability of key parts of the bearing directly determines the performance of the equipment.

WIND ENERGY

As a renewable and clean energy source, wind power is rapidly developing all over the world. Large wind turbines are giant machinery. Nowadays, many 2MW wind power plants under construction have wind turbine blades with a length of about 40 meters, a rotating shaft with a height of 60 to 100 meters and total weight of more than 200 tons. Therefore, the bearings used in wind power must also be large, with an inner diameter ranging from 100 mm to 700 mm. Some models require bearings with an inner diameter of nearly 2 meters. Bearings for wind turbines require high reliability, because the bearings are designed to keep the windmill running for 20 years; and when the fault occurs, the parts are not easy to replace (the bearing is used at a long distance from the ground). Bearing manufacturers need to have a high degree of computer analysis technology and exquisite skills in materials and heat treatment, and need to master the test evaluation technology for large bearing .
