Reliable Dielectric Protection – Plasma-sprayed alumina coating (100–500 μm) provides 1000–3000 V dielectric strength, preventing shaft-current-induced fluting and lubricant degradation.
C3 Internal Clearance for High-Speed Operation – Extra clearance accommodates thermal expansion and high rotation speed, ensuring smooth long-term performance.
Direct Replacement Compatibility – Fully interchangeable with SKF 6212M/C3VL0241, FAG 6212-M-J20AA-C3, and NKE 6212-M-C3-SQ77, offering identical fit with improved cost efficiency.
Solid Brass Cage for High Thermal and Mechanical Stability – The M-design brass cage withstands high temperatures and dynamic loads, offering superior durability compared to steel cages.
TFL 6212M/C3VL0241 matches SKF, FAG, and NKE equivalents in dimensions, tolerances, brass cage design, and insulation performance. Every bearing undergoes dielectric withstand and dimensional testing, ensuring full compatibility with improved reliability and cost benefits.

M-design solid brass cage — high mechanical and thermal strength
Dielectric strength 1000–3000 V; insulation resistance 50–200 MΩ
C3 internal clearance — suitable for high-speed and warm-running bearings
TFL 6212M/C3VL0241 is widely used in VFD motors, generators, centrifugal pumps, fans, power-plant auxiliary drives, and wind turbine generators. The ceramic insulation prevents shaft currents, while the C3 clearance and brass cage enhance performance in high-speed and warm-running applications.
TFL 6212M/C3VL0241 is suitable for Siemens 1LE0001 and ABB M3BP VFD motors. PWM switching often introduces shaft currents; the ceramic insulation withstands up to 3000 V, while the brass cage provides thermal stability (compatibility example only).
Suitable for Grundfos CR multistage pumps, KSB Eta centrifugal pumps, and Siemens industrial fans. Humidity and continuous temperature rise demand reliable insulation and cage stability—both supported by TFL’s VL0241 insulated design (compatibility illustration only).
TFL 6212M/C3VL0241 can be applied in generator systems of Goldwind GW121/2500, Vestas V90, and Siemens Gamesa 2.3 MW turbines. Wind turbines operate under humidity, vibration, and VFD influences; TFL’s insulation helps mitigate shaft-current-related risks (illustrative compatibility example).
