Product Description

6330-J20C  Insulated Deep Groove Ball Bearing Motor Bearing


Current-insulated bearings and hybrid bearings

  • Current-insulated bearings have either an outer ring (J20 A, J20 AA, J20B) or an inner ring (J20C) that is insulated with thin ceramic coating.
  • Different coating types are available for optimum functional performance.

Current-insulated bearings have the same dimensions and load carrying capacities as those without insulation, which makes them perfectly interchangeable.
The most common type of insulation used in electric motor applications is the J20AA coating. It offers excellent protection against passage of electrical current, even in damp atmospheres.
Bearings with ceramic coating are available with seals also.

Bearings with J20C coating on the inner ring are used in special applications as well as applications where the outer ring rotates. Z shields can be used as well.

Ordering examples:

  • 6220-2RSR-J20AA-C3
    Deep groove ball bearing with a coated outer ring, with seals on both sides and radial clearance C3.
  • NU214-E-M1-F1-J20B-C4
    Cylindrical roller bearings with a coated outer ring and radial clearance C4.
  • 6330-J20C
    Deep groove ball bearings with a coated inner ring

Hybrid bearings (HC): Hybrid bearings are characterized by the fact that the rolling elements are made of ceramic. They offer maximum protection against passage of electrical current. At the same time, hybrid bearings are suitable for higher speeds and have better dry-running characteristics.

Ordering examples:

  • HC6214-M-P6-C3
    Deep groove ball bearing with ceramic balls; machined brass cage; increased accuracy P6 and bearing clearance C3.
  • HCN1020-K-M1-SP
    Cylindrical roller bearing with ceramic rollers; tapered bore; machined brass cage; increased accuracy SP.
6330 M/C3VL0241 bearing is insulated bearing and deep groove ball Bearings with a Ceramic Coating, the bearing have an electrically insulating coat on the outer ring(suffix VL0241) or on the inner ring(suffix VL2071), respectively. insulated bearing are widely used in generator, Alternator ,there are 100μm thick coating on the surface of inner or outer ring, the insocoat bearing can bear voltages up to 1000V DC,insulated & insocoat bearing can keep away from moisture and humidity,it can carry radial and axial loads in both directions.

6330 M/C3VL0241 bearing provide a bearing function and electrical insulation,virtually eliminates premature bearing failure caused by stray electric currents,electrical insulated bearing can reduce the number of failures and improve the machine uptime,reduce the cost of maintenace.
