the application features of fan bearing are continuous, high-speed operation, bearing easy to heat, and the bearing requires low noise, long life and high reliability.

features:

1.our company fan bearings meet the standard: jb / t7753-2007 <> standard.
2.using martensite quenched bearing steel ring ,roller with a diameter greater than 15mm and steel balls with diameters greater than 25mm perform high temperature tempering at 250 ° c.
3.bearing accuracy grade is p6 level accuracy level,which be specified by gb/t307.1.
4.radial clearance is controlled according to the requirements of the fan operating conditions,to ensure the fan bearing low noise, low temperature rise, long life
5.bearing rings and rolling body for 100% inspection crack detection
