Common Applications of Electrically Insulated Bearings

The 6220/C3VL0241 electrically insulated bearing is widely used in medium to large electric motors, pumps, and rotating machinery where stray electrical currents may pass through the bearing. The insulation layer protects against current-induced damage, especially in systems driven by frequency converters (VFDs).

electrically insulated bearings on the Non-Drive End (NDE) to prevent inverter-induced shaft currents and leakage loops.

Electric Motors

The 6220 is frequently used on both the Drive End (DE) and Non-Drive End (NDE) of electric motors to prevent inverter-induced shaft currents, ensuring smooth rotation and minimizing downtime. For example, in the T-T Electric AMP series low-voltage motors (used in industrial automation and conveyor systems), applying the 6220/C3VL0241 insulated bearing on the N-end in applications exceeding 100kW effectively interrupts the leakage current loop.
Insulated motor bearing solution for heavy-duty centrifugal and submersible pumps, designed to stop stray currents and extend seal life in water processing systems.

Pumps

In centrifugal and submersible pumps, insulated bearings like the 6220/C3VL0241 are used to manage electrical stress on motor-driven impellers, preventing corrosion and extending pump life in water or chemical processing. For instance, in Grundfos CR series vertical multistage pumps (widely used in water supply and irrigation), this bearing insulates the motor end from stray currents caused by variable speed drives. This ensures reliable sealing and flow rates while reducing maintenance in humid conditions.

High-performance electrically insulated bearings for railway traction motors, preventing electrical pitting from DC currents in high-speed train axle assemblies.

Railway Traction Systems

In railway applications, these bearings are critical for traction motors to prevent electrical damage from pantograph currents, supporting high-speed and reliable transport. For example, in the Siemens Desiro series commuter trains (operating on urban rail networks in the UK and Germany), the 6220/C3VL0241 is used in axle-mounted motors to insulate against DC currents, preventing pitting and ensuring smooth acceleration and deceleration.

Final bearing selection should be confirmed through verification of dimensions, clearance class, insulation type, and operating conditions. For selection assistance or technical consultation, please contact the TFL engineering team for support.

Q&A

Can this bearing completely replace a standard 6220 deep groove ball bearing? Are there any special installation requirements?

Yes, it is a complete replacement. The TFL 6220/C3VL0241 shares identical dimensional tolerances with standard 6220 bearings (100mm ID, 180mm OD, 34mm Width), meaning it can be installed directly into existing housings and shafts without any mechanical modifications. While standard mounting tools and methods should be used, special care must be taken to avoid sharp impacts or scratching the outer ring, as this could damage the insulation coating.

Can I use the TFL 6220/C3VL0241 to replace SKF or FAG products?

Absolutely. Our bearing is engineered as a direct "interchange" part. It fully complies with ISO dimensional standards, and its electrical insulation resistance (>50MΩ @ 3000V) meets the rigorous standards of major brands like SKF, FAG, and NTN. Choosing TFL simply provides a more cost-effective solution for your maintenance budget without compromising performance.
