Slewing bearing

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.  

About the product

Three-row roller slewing ring has three seat-rings,which separating the upper,lower and radial raceways,via which the load of each row of the rollers maybe specified.It may bear different loads simultaneously and its load capacity is the largest one among the four models.Owing to large size of its aexl and radius,it is sturdy and especially suitable for heavy-duty machines which require large working diameter,such as bucketwheel excavators,wheeled cranes,deck cranes,port cranes,steel transporters,heavy-duty mobile cranes etc

                                                       Chief engineer introduction

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.
