Product Description
Low structural characteristics: high purity on inner and outer bearing steel or double vacuum high temperature bearing steel, with special heat treatment, cold treatment technology and material modification, make this series of bearing fatigue life of great increase in single row and double row roller bearings have two types of bore cylindrical and conical, on the main shaft in order to easy to adjust the radial internal clearance after installation, the spindle rotation accuracy and radial stiffness, generally USES cone bearing.
Low cage: there are two: outer guide of PEEK resin keep frame and copper alloy guide roller cage; Can choose according to different purposes. High speed single row cylindrical roller bearings use PEEK cage; Using the limit temperature 240 DHS С. Double row short cylindrical roller bearing adopts copper alloy cage guide roller; Using the limit temperature 300 DHS С
Low speed factor: bring NN30 series of copper alloy cage
Grease lubrication DmN 650000 or less limit speed N/Dm 650000 or less
Dm - bearing diameter (minimal) oil lubrication in DmN 810000 or less
Bring N19; N10 series of copper alloy cage
Grease lubrication DmN 900000 or less limit speed N/Dm 900000 or less
Dm - bearing diameter (minimal) oil lubrication in DmN 1000000 or less
Bring N19; N10 series PEEK cage
Grease lubrication DmN 1230000 or less limit speed N/Dm 1230000 or less
Dm - bearing diameter (minimal) oil lubrication in DmN 1430000 or less
Bring HCN10 series PEEK cage
Grease lubrication DmN 1560000 or less limit speed N/Dm 1560000 or less
Dm - bearing diameter (minimal) oil lubrication in DmN 1820000 or less
Low scope of application: double row short cylindrical roller bearing, suitable for machine tools on the high requirement of radial stiffness of the main shaft; Single row cylindrical roller bearing is suitable for machine tools on the radial stiffness and high demand for high speed spindle. For example, numerical control lathe spindle, CNC grinding machine for grinding wheel spindle, aircraft engine spindle, precision mechanical transmission, etc.
