Machine tool

Metallurgical Industry

In the metallurgical industry, the working environment of rolling mills, continuous casting machine or converters is really harsh. These conditions require bearings to withstand the harsh effects of heavy load, high temperature, dust and water. In order to meet the requirements of metallurgical industry, ZYS R & D teamhas developed bearings products with high quality, high precision and long service life and also can offer the bearing solutions for manufacturers in the metallurgical industry.

Wind power

Construction Machinery

ZYS large-size heavy duty precision bearings are manufactured in our second industry park,which covers 133,333㎡ with total investment of 438 million RMB.
The inner ring,outer ring and rolling elements of bearing under normal working conditions are made of high carbon chromium bearing steel.To meet the special requirements,such as super high speed,wear-resisting,low temperature rising,long life and high reliability etc.,it’s suggested to use hybrid ceramic ball bearings.

Construction machinery

Rail Transportation

ZYS has been committed to the research and development of bearings for rail transportation for a long time to meet the increasing requirements for rail transportation,such as higher speed,load,reliability and etc.

4 point contact ball bearing

2022-05-20 11:33:52

Four-point contact ball bearing is a single-row angular contact ball bearing with separate inner and outer rings. The inner ring is divided into two parts, and one bearing can bear axial loads in two directions. The contact angle is 35°, and the axial load capacity is large, which is suitable for bearing pure axial load or synthetic load with large axial load.Four-point contact ball bearings are interchangeable with face-to-face or back-to-back angular contact ball bearings.Four-point contact ball bearings use copper alloy machined cages.
