6319M/C3VL0241 electrically insulated deep groove ball bearing 6319 ball bearing 6317 6318/C3VL0241

Electrically insulated bearings adopt a special spraying process to spray high-quality film on the outer surface of the bearing. The film has strong bonding force with the substrate and good insulation performance, which can avoid the electric corrosion effect of the induced current on the bearing and prevent the current from affecting the grease and rolling elements. , The damage caused by the raceway will improve the service life of the bearing.
