Super-sized equal-section thin-walled bearings LKG420XP0 and LKG580XP0 successfully delivered
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*25.4mmLKG420XP0LKG580XP0 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.

Introduction of LZK New Precision bearings Final Processing Equipment
1.Introduction of Super Refine Grinding（1）What is Super Refine Grinding? Super Refind Grinding is a finishing method，which is under good lubricating and cooling conditions,use a fine-grained abrasive(oil stone)to exert a small pressure on the workpiece,perpendicular to the direction of rotation of the workpiece,and perform a fast and short reciprocating oscillatory motion on the workpiece which is rotating at a certain speed.（2）The role of Super Refine Grinding In the manufacturing process of rolling bearings,superfinishing is the last process of bearing ring processing.It can reduce or eliminate the circular deviation left by grinding,correct the shape error of the groove;refine its surface roughness,improve the surface physical and mechanical performance.It plays an important role in effectively reducing the waviness of the groove,reducing the vibration and noise of the bearing,improving the lifecycle of the bearing.2.LZK Super Refining Machine Recently,LZK newly purchased four sets of Super Refining Machine for the final processing of large and extra-large precision bearings.The processing size range coversφ200-φ1800,which can be used for the processing of bearing grooves,rollers,ribs,etc.Among bearing enterprises of the same scale and type,the configuration of LZK’s equipment reaches to the top level.（1）CNC bearing Groove Super Refining Machine Processing type:Processing inner and outer grooves of Deep groove ball bearings,Angular contact ball bearings,Four-point contact ball bearings Processing range:Outer diameter:φ200-600mm,Workpiece width 15-200mm,Groove curvature R≤100mm,maximum Workpiece weight 500kg Processing accuracy:Roughness Ra≤0.05um（2）CNC bearing Groove Super Refining Machine Processing type:Processing inner and outer grooves of Deep groove ball bearings,Angular contact ball bearings,Four-point contact ball bearings Processing range:Ring outer diameter:600-1200mm,Workpiece width 50-250mm,Groove curvature R≤100mm,maximum Workpiece weight 500kg Processing accuracy:Roughness Ra≤0.05um（3）CNC Bearing Raceway Super Refining Machine Processing type:Processing inner and outer raceways of Cylindrical roller bearings and Tapered roller bearings Processing range:Ring outer diameter:φ260～φ600mm,Workpiece inner diameter 220-540mm,Workpiece height 25-200mm,maximum Workpiece weight 500kg Processing accuracy:Roughness Ra≤0.05um（4）CNC Multi-function Bearing Super refining machine Processing type:Processing the inner and outer ring raceways and inner ring ribs of Tapered roller bearings,the inner and outer ring raceways and ribs of Cylindrical rollers bearings,the grooves of inner and outer rings of ball bearings,the inner ring receways of Spherical roller bearings Processing range:Outer diameterφ600～φ1600mm,Workpiece width 30～500mm,maximum angle 40°of Tapered roller bearing,maximum Workpiece weight 2000Kg Processing accuracy:roughness Ra≤0.10um
