Product Description
Deep groove ball bearing 6306 KOYO Bearing Japan
What is Deep Groove Ball Bearings?
Single-row deep groove ball bearings support radial and axial loads and they are also suitable for high speeds. Deep groove ball bearings cannot be dismantled.Deep groove ball bearings with current insulation Damage due to excessive voltage can occur in the bearing supports of electric motors under unfavorable conditions.Magnetic asymmetries,which cannot be completely avoided despite careful manufacturing processes, cause the voltage between the rotor and the stator to drop.The electric circuit is then closed via the bearing.we supply innovative current-insulated bearings,which also include hybrid bearings with ceramic rolling elements.
- Inner or outer rings coated with oxide ceramics for breakdown voltages of up to 1000 V
- Hybrid bearings with rolling elements made of current-insulated ceramic
