Common Applications of Electrically Insulated Bearings

The 6216/C4VL0241 is an insulated deep groove ball bearing designed to prevent electrical erosion caused by current passing through the bearing in industrial equipment. Its aluminum oxide coating provides electrical insulation up to 3000 V DC. It is suitable for high-power machinery such as electric motors, pumps, and generators, particularly in environments using Variable Frequency Drives (VFDs), effectively preventing lubricant degradation and surface damage caused by bearing currents.
The picture shows the TFL bearings, especially the Electrically Insulated Ball Bearings used in the motor.

VFD Industrial Motors

The 6216/C4VL0241 is commonly used for locating at the Non-Drive End (NDE) of low-voltage variable frequency drive (VFD) motors with power ratings around 45kW to 90kW, where the insulating coating cuts off the shaft current loop. In Siemens motors with Frame Size 225, the standard configuration or option for the Non-Drive End (NDE) often includes a 6216 bearing. When this motor is marked for “converter operation,” Siemens technical manuals recommend replacing the bearing at the NDE with an insulated bearing.
The picture shows the bearings of TFL, which are the electrically insulated ball bearings used in the pump.

Industrial Pumps

The 6216 is commonly used at the upper end or tail end (non-drive end) of vertical or horizontal motors driving large centrifugal pumps. Grundfos NKE 100-250 or similar single-stage end-suction pumps are typically equipped with 55kW-75kW motors (such as those manufactured by Siemens or WEG). When driven by a VFD cabinet, maintenance manuals recommend replacing the motor's tail-end bearing with a 6216/C4VL0241 to extend service life.

Wind Energy

Wind turbine nacelles are filled with high-frequency interference. The 6216/C4VL0241, a high-clearance insulated bearing, is commonly used at the Non-Drive End of Doubly Fed Induction Generators (DFIG) (for smaller turbines) or inside the Yaw Motors of large turbines. Vestas V80 series turbines are equipped with independent forced cooling systems. The cooling fan motors operate in environments with large temperature differences (requiring C4 clearance). The 6216 is a common model for such medium-sized auxiliary motors.

*The brands and series mentioned are provided for industry illustration only. 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

Does the insulation coating affect the C4 clearance dimensions?

No. The TFL manufacturing process accounts for the coating thickness. The final dimensions (140mm OD) and the internal C4 radial clearance are strictly within ISO tolerances after the coating is applied. It fits standard housings perfectly.

Is this bearing suitable for horizontal and vertical mounting?

Yes, the 6216/C4VL0241 is a deep groove ball bearing suitable for both mounting orientations. However, for vertical mounting in large motors, ensure the axial load does not exceed the bearing's capacity, or consider our paired installation options.
