TFL 6218/C3VL0241 is a direct functional equivalent to SKF and FAG in terms of mechanical specifications and dielectric properties. Its standardized design ensures a “plug-and-play” installation in existing motor and pump systems without modification. Each bearing undergoes 100% dielectric and dimensional inspection to guarantee reliability under harsh operating conditions.

TFL specializes in the R&D and manufacturing of high-performance insulated bearings, utilizing optimized alumina spraying processes to solve premature failures caused by high-frequency shaft currents. Beyond premium products, our professional engineering team provides expert selection advice and failure analysis. From ISO 9001 quality control to flexible no-MOQ ordering, TFL is committed to being a trusted partner for cost optimization for global industrial clients.
Plasma-sprayed Alumina Coating — Uniform ceramic layer (100–500 μm) on the outer ring for high bond strength.
High Reference Speed — Capable of stable operation up to 8500 r/min.
Large Bore Design (90mm) — Optimized for heavy-duty industrial motor shafts.
TFL 6218/C3VL0241 insulated bearings are widely used in Variable Frequency Drive (VFD) motors, rail traction motors, high-power industrial fans, and centrifugal pump systems. This model effectively blocks induced currents caused by asymmetrical magnetic fields or inverters, preventing “fluting” damage on raceways, making it the preferred choice for MRO in power, paper, and chemical industries.
TFL 6218/C3VL0241 is suitable for heavy-duty industrial VFD motors such as the Siemens 1LE1 and ABB M3BP series. Under high-frequency PWM interference, standard bearings often fail due to shaft currents; TFL’s 3000V insulation ensures long-term stability in these high-performance systems and is a recommended alternative to SKF equivalents.
In VFD-driven large industrial pumps by Grundfos or centrifugal fans by Howden, TFL 6218/C3VL0241 is highly recommended to withstand shaft voltage surges. Its C3 clearance accommodates thermal expansion during heavy-load operation, preventing unplanned downtime due to electrical erosion and significantly lowering maintenance costs.
For wind turbine generators (such as units in Vestas or Goldwind systems), TFL 6218/C3VL0241 can be applied to the non-drive end bearing position. In harsh outdoor environments with significant temperature fluctuations, its ceramic coating provides excellent chemical stability and dielectric strength, protecting the drivetrain from stray currents.
