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.
