6216-J20AA-C3 Current Insulating Bearing with steel cage

6216-J20AA-C3 is a single row deep groove ball electrically insulated bearing with a special outer ring ceramic coating to protect the bearing and avoid the electro-corrosion of the induced current on the bearing, and prevent the current from damaging the grease and rolling elements and raceways.

The J20AA indicates the addition of an aluminum oxide coating on the outer ring to withstand voltages up to 3.000 V DC.

The spec of 6216-J20AA-C3 Electrically insulated bearings:

Full dimension: 80X140X26mm

Cage: steel cage C3

Normal models: 6216-C3, The weight of 6216-J20AA-C3 is 1.4kg.

1.S: Steel Cage, Ball Centered.
2. J20AA: External surfaces of the outer ring coated with ceramic. The coating is sealed with a resin to protect against
the conductive effects of water and moisture. This basic coating can withstand voltages up to 3.000 V DC.
3. C3: Internal clearance greater than Normal. The extra internal clearance allows expansion due to high speeds or temperatures.

The electrically insulated bearing TFL made can replace any other famous brand electrically insulated bearing with good proformance.

Why choose TFL Electrically insulated bearing?

1. TFL electrically insulated bearings use a special spraying process to spray high-quality coatings on the outer surface of the bearings. The coatings have strong bonding with the substrate and good insulation properties. They can avoid the electro-corrosion of the bearings by the induced current and prevent the current from damaging the grease, rolling elements and raceways. 2. Advantages of TFL insulated bearings. Insulated bearings can avoid damage caused by electrical corrosion. Compared with ordinary bearings, they can be used in motors to ensure more reliable operation. Compared with other insulation methods, they are more cost-effective and reliable. The dimensions and basic technical characteristics of insulated bearings are the same as those of non-insulated bearings and are 100% interchangeable.
