SKF 6313M/C3VL024104 Insocoat Insulated, Single Row Deep .

By integrating the insulating properties into the bearing, insocoat bearings can improve reliability and increase machine uptime by virtually eliminating the problem of electrical erosion. An insocoat bearing is a standard bearing that has the external surfaces of its inner or outer ring plasma-sprayed with an aluminum oxide to form a coating.

The aluminum oxide layer is a pure insulator and, therefore, only the ohmic resistance, R, of the layer is the important quantity. The breakdown voltage of the standard layer is given as 1,000 VDC and the resistance is bigger than 50 MΩ, which provides efficient insulation of the bearing.

Oxide Ceramics – Zirconium Oxide (ZrO2) - ceramtec.c

The oxide ceramic zirconium oxide, or zirconia (ZrO2) is a ceramic material with very high crack propagation resistance and thermal expansion. These properties are the reason why zirconium oxide ceramics from CeramTec are chosen to join ceramic and steel.

6317-J20AA-C3 FAG • ABF Sto

A special coating on the outer ring (J20AA) protects against bearing damage and eventual failure due to the passage of electric current. Electrically insulated bearings are marketed by FAG with the suffix J20. The J20AA indicates the addition of an aluminum oxide coating on the outer ring to withstand voltages up to 3.000 V DC. Specs 6317-J20AA ...

INSOCOAT - skf.c

INSOCOAT bearings are insulated bearings that can be retrofitted to replace non-insulated bearings. Using plasma spraying technology, the exterior of the mating surface is coated with a thin layer of aluminum oxide. This extremely coherent, thin coating of uniform thickness is further treated to make it virtually impervious.

SKF intros higher-performance INSOCOAT bearin

SKF’s INSOCOAT bearings have an electrically insulating coating on the external surfaces of its inner or outer ring, and are plasma-sprayed with an aluminum-oxide coating. The coating, which is naturally hygroscopic, is sealed with a resin to protect against the conductive effects of high humidity and moisture ingress.


Ball bearings are available in full ceramic or as hybrid material. Emphasis is on application at higher temperatures and under corrosive conditions. Lubrication is often less critical. The liquid medium surrounding the ball bearing can give sufficient lubrication. At low loads and speeds there is no need for lubrication at all.
