Recently,the super-sized equal-section thin-walled four point contact ball bearings LKG420XP0 and LKG580XP0 which designed and manufactured by LZK have been successfully delivered to foreign customer.

　　For one of them,LKG580XP0 is the largest equal-section thin-walled bearing known in China by far.These two super-sized equal-section bearings fill the gap in the domestic super-sized equal-section bearing market.

　　The sizes of the two bearings are as follows:

　　LKG420XP0 1066.8*1117.6*25.4mm

　　LKG580XP0 1473.2*1524*25.4mm

　　In the process of producing these two super-sized precision thin-walled bearings,the deformation problem during turning,heat treatment and grinding is the biggest challenge we face.How to control the deformation and minimize the amount of allowance during the bearing processing?LZK has formed a set of unique processing methods based on its rich experience in the production of equal-section thin-walled bearings for many years.

　　As a professional manufacturer of large precision thin-walled bearings,LZK has achieved a maximum outer diameter of equal-section thin-walled bearings of 1524mm.In the process of exploring the production and processing of large thin-walled bearings,LZK will continue to work hard to provide customers with larger and thinner products to meet the diverse needs of customers.
