Common Applications of Electrically Insulated Bearings

Electrically insulated deep groove ball bearings, as core components, effectively block current paths to protect critical rotating machinery from VFD-induced shaft currents. This prevents electro-erosion damage, extends bearing life, reduces maintenance costs, and ensures continuous and stable equipment operation under harsh conditions.

The picture shows the structure of the motor. The bearings are respectively used in DE and NDE.

Electric Motor DE Bearing and NDE Bearing

In various low-voltage electric motors, electrically insulated bearings can protect against the effects of shaft currents induced by VFDs, ensuring stable operation of the motor in industrial automation and continuous production environments. For example, Siemens Squirrel-cage motors (such as 1LA, 1LG, and 1MA motors) commonly use 6216 bearings as drive-end bearing and non-drive end bearing. The 6216/C3VL0241 bearing can prevent premature failure caused by electric arcing, maintaining stability and long-term operation in high-frequency conditions.
The picture shows the application of the 6216/C3VL0241 bearing in Grundfos's CR (vertical multistage) series.

Pump Motor

In pump motors/rotor shafts under long-term operation or scenarios with pump-driven variable frequency drives, shaft voltage can also cause bearing electrical erosion. Many pump manufacturers use insulated bearings at the motor end or rotor/pump cavity bearing positions to protect the bearings. For example, Grundfos's CR (vertical multistage) series uses the 6216C3 bearing as an accessory. The insulating coating of the 6216/C3VL0241 bearing can minimize the risk of current passing through the bearing, helping the bearing reduce downtime under harsh conditions such as water treatment or chemical processing, especially in supporting high-pressure fluid handling in industrial and municipal water supply systems.

a railway and some insolated bearing used in traction motor

Railway Traction Motors

Railway traction motors in electric locomotives and multiple units are typically driven by frequency converters. These converters generate high-frequency voltages, which can create a potential difference between the inner and outer rings of the motor bearings, leading to current flow through the bearings. Railway traction motors utilize electrically insulated bearings to effectively counter the shaft currents generated during operation. For example, the 6216/C3VL0241 bearing is used in ŠKODA ELECTRIC traction motors for the Cityrunner low-floor tramway in Graz, Austria. Serving as the locating bearing, it supports applications with a maximum speed of 70 km/h and a power of 8 x 50 kW. In operation since 2001, the 6216/C3VL0241 bearing provides reliable electrical insulation protection in high-vibration and variable-speed environments.

Final bearing selection should be confirmed through verification of dimensions, clearance class, insulation type, and operating conditions.

Q&A

How do TFL 6216 series electrically insulated bearings differ from regular bearings?

TFL 6216 series electrically insulated bearings feature a special ceramic coating on their outer or inner ring surface, which effectively blocks electric current from passing through the bearing. This is crucial in applications prone to shaft currents, such as inverter-driven motors and generators. Regular bearings do not possess this electrical insulation capability.

If I require different internal clearance or variant; what options exist?

We offer variants such as 6216/C4VL0241 (clearance C4), 6216M/C4VL0241, 6216M/C3VL0241 etc. Please contact us for individual customization or selection.
