Common Applications of Electrically Insulated Bearings

Electrically insulated bearings are widely used in applications where stray currents may cause pitting or premature failure, such as motors, generators, and rotating machinery. The insulation layer acts as a barrier, preventing electrical current from passing through the bearing, thereby reducing corrosion and maintenance requirements.

Industrial Motors

6220 bearings are commonly used in medium-size high-voltage motors, VFD-driven motors, and generators at both the drive end (DE) and non-drive end (NDE). In WEG W22 series motors, 6220 insulated bearings are typically installed at the NDE for compressor or blower applications, providing enhanced protection in humid environments such as food processing facilities. The insulation prevents the characteristic “washboard” fluting on raceways—one of the primary causes of premature motor failure in VFD applications.

Heavy-Duty Centrifugal Pumps

In VFD-controlled pump systems, the motor-drive combination often introduces bearing current issues, making insulated bearings especially critical. Sulzer Ahlstar series process pumps frequently use bearings in the 6220 size. When these pumps are retrofitted with VFDs for energy savings, standard bearings often fail due to electrical discharge machining (EDM) currents. The VL0241 coating ensures that electrical drive systems do not damage the mechanical bearing components.

Rail Traction Motors

Railway traction motors operate under extreme electrical and mechanical stress. Manufacturers such as Bombardier use electrically insulated bearings in traction motor designs to prevent high-voltage traction currents from passing through the rolling elements. The 6220M/C3VL0241 is suitable for rotor support in these motors. The “M” machined brass cage withstands high impact loads, while the insulation ensures return currents flow through grounding carbon brushes rather than through the bearing.

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

How do I determine if my equipment needs insulated bearings?

If your motor or generator is driven by a Variable Frequency Drive (VFD), or operates in environments with stray currents (such as railways or near large welding equipment), and your bearings show failure characteristics like regularly spaced pitting, dull grey fusion marks (electrical erosion), or washboard-like fluting, you should consider insulated bearings. For new projects, high-voltage motors, traction motors, and wind turbines typically specify insulated bearings by default.

Can 6220M/C3VL0241 directly replace a standard 6220 bearing?

In terms of boundary dimensions, replacement is usually possible. However, it is still necessary to confirm the required clearance class, cage preference, actual insulation requirement, and the motor’s drive and grounding design—especially in VFD applications—before making a replacement decision.
