FAG Current-Insulated Bearings NJ219-E-TVP2-J20AA Bearing 95×170×32mm Used In wheelsets and traction motors
FAG Current-Insulated Bearings NJ219-E-TVP2-J20AA is an Insulated cylindrical roller Bearing design. its dimension is 95×170×32mm , it has the same dimension and the same design with normal chrome steel NJ219-E-TVP2 bearing and also the same nylon cage. but the most different is NJ219-E-TVP2-J20AA bearing with Aluminium Oxide Coating . the coating can Electrical Resistance Voltages up to 3000 V DC.
A much more economical solution is to provide for the use of FAG Current-Insulated Bearings NJ219-E-TVP2-J20AA during the planning stage. This reduces maintenance and repair costs, and increases machine availability – all of which means greater value for the customer.

FAG Current-Insulated Bearings NJ219-E-TVP2-J20AA / INSOCOAT bearings:
- are designed to prevent electric current from passing through the bearing
- have the external surfaces of either their inner or outer ring coated with an insulating aluminum oxide layer, by applying a sophisticated plasma-spray process for an outstanding quality finish
- are a very cost-effective solution compared with other insulation methods

Features and Benefits of FAG Current-Insulated Bearings
• Oxide ceramic coatings (J20...) provide a high level of insulation. Plasma spraying is used to apply these coatings to the bearing surfaces
• Thanks to a special sealant, the J20AA coating retains its insulating properties even in a damp environment. The resulting oxide ceramic coating is very hard, wear-resistant, and a good thermal conductor.
• The external dimensions of the current-insulated rolling bearings are in accordance with DIN 616 (ISO 15). This means that they are interchangeable with standard bearings.
• For special applications, such as those with a rotating outer ring, we recommend using an inner ring coated with J20C.
• Starting with the 62-series and up, coated deep-groove ball bearings are available in both open and sealed versions (with lip seals on one or both sides). This enables the user to also benefit from the advantages offered by for-life lubrication.
