Our Regular Products
We offer a variety of electric insulating bearings to choose from. The standard bearing classifications include deep groove ball bearings, cylindrical roller bearings, and tapered roller bearings. We have the standard bearing classifications shown below in stock and can deliver quickly.
-
Electrically Insulated Deep Groove Ball BearingsThe most versatile insulated bearing, ideal for high-speed applications and moderate loads in electric motors.
-
Electrically Insulated Cylindrical Roller Bearings
Engineered for high radial loads and impact resistance, widely used in traction motors and large industrial motors.
-
Electrically Insulated Tapered Roller Bearings
Capable of handling both radial and axial loads, making it the ideal solution for heavy-duty and specialized equipment.
-
Spherical Roller Electrically Insulated Bearings
Designed to handle misalignment and heavy-load conditions, providing superior reliability in harsh industrial environments.
Product Range
For bearing types and sizes not listed in the product tables (deep groove ball bearings, cylindrical roller bearings, Tapered roller bearings), please contact our online sales.
For smaller bearings than those listed, we recommend TFL hybrid ceramic bearings.
In addition to the standard assortment, TFL also offers special electrically insulating bearings and bearing units with complex toroidal geometries, such as:
Four-point contact ball bearings (fig. 1)
Flanged tapered roller bearings (fig. 2)
Tapered roller bearing units (TBU) (fig. 3)
Traction motor bearing units (fig. 4)
The TFL Advantage
We integrate patented technology, stringent quality control, and supply chain efficiency to deliver unmatched reliability and value to our partners.

Bearings For Oil & Gas Industry
We utilize a robust aluminum oxide coating to provide superior electrical insulation in our bearings. This is vital for Oil & Gas operations, where stray currents from VFDs can cause sparks and lead to catastrophic failure in potentially explosive atmospheres. As a dedicated partner, we deliver insulated bearings that enhance equipment safety and maximize uptime for your critical machinery.
Hot Market
