Dalian changhui Slewing Bearing Co,. Ltd is specialized in slewing bearing design and manufactures.
Main products are four series of slewing bearing:single-row sphericaltype,double-row spherical type,three-row spherical type,three-row rolling type and crossover rolling type.They are applied for all srandards or non-srandard,external gear ,internal gear or no gear ,specification ranged 200-4500mm.Products are sold to all over China,and export to  U.S, Germany,Australian,Singa-pore and other overseas countries.We will provide to our customers with reliable design,Precise manufacture,commitment and timely service and creat mutual values.

Our  chief engineer,Mr.Zheng Xiangchen,graduated from Herbin Military Instrtute of Engineering in 1966.During his college time,he took study in the School of Engineering Machinery School of majoring in bearing,and participated in the designing and manufacturing of the first turntable bearing in China in 1964.Over the years,Mr.Zheng has been engaged in bearing designing and manufacturing.He used to be the chief scientist of giant enterprises such as Wafangdian Bearing Gruop.The Φ5082mm Triple-row cylindrical roller slewing bearing used in Qinhuangdao Port today was designed be him in 1995,which replaced the crossed roller slewing bearing imported from Japan.After 2000,Mr.Zheng designed and manufactured manu kinds of slewing bearings which replace imported ones from oversea such as marine slewing bearing which load carrving capacity over 9 million tom-meter,crossed cylindrical roller slewing bearing used in Computer to mography
about the product:The single-row four point contact ball slewing ring is composed of 2seartrings.
It features compact in design,light in weight,the balls contact with the circular raceway at four points,via which the axial force,radial force and resultant moment may be born simultaneously.It may be used for slewing conveyers,welding opertaing consoles,light,medium duty cranes,excavators and other engineering machines.

Slewing bearing has a wide range of applications in our life, referred to as "the machines arthrosis ", and so is widely used in engineering machinery, construction machinery, environmental protection and light machinery, mining and metallurgical machinery , the port and ship machinery, food and packaging machinery, petrochemical machinery, engineering vehicles and military equipment, apparatus and instrumentation industries.Slewing beaings have With the following characteristics, Compact structure and light weight, structural rigidity, and the smooth operation and high precision, safe and reliable.
