Superior electrical insulation – plasma-sprayed alumina coating (100–500 μm) on outer ring) delivers up to 3000 V DC breakdown voltage and 50–200 MΩ resistance, completely blocking shaft currents and preventing fluting damage.
High load capacity and speed capability – 85.2 kN dynamic load rating and reference speed up to 11000 r/min, precision-ground raceways deliver low vibration and low noise even under variable frequency operation.
100 % interchangeability – identical dimensions, clearance and cage design to SKF 6312/C3VL0241 and FAG 6312-J20AA-C3, enabling direct replacement without any motor modification.
No MOQ, fast delivery & full technical support – stock available, typical lead time 5–10 days, free selection calculation, installation guidance and failure analysis included.
TFL 6312/C3VL0241 is fully interchangeable with SKF, FAG, NKE, NSK, and NTN equivalents in dimensions, clearance, and insulation performance. Each unit undergoes dielectric and dimensional inspection to guarantee reliable replacement performance with improved cost efficiency for both service and OEM applications.

TFL utilizes state-of-the-art plasma spraying technology to apply a uniform and strongly bonded alumina ceramic coating on the outer ring for reliable long-term insulation. Certified to ISO 9001, ROHS and REACH, we offer end-to-end support from selection to after-sales, achieving significant total cost of ownership savings without compromising reliability.
Plasma-sprayed alumina coating on outer ring – thickness 100–500 μm, breakdown voltage 1000–3000 V DC.
Standard C3 clearance + sheet metal cage, identical dimensions to standard 6312 bearing, direct replacement.
Reference speed up to 11000 r/min, dynamic load rating 85.2 kN, suitable for high-speed VFD applications.
The TFL 6312/C3VL0241 is widely used in 75–200 kW VFD motors, generators, centrifugal pumps, Roots blowers, compressors and rail traction motors. The ceramic insulation reliably blocks high-frequency shaft currents, substantially reducing electrical erosion and extending service life.
TFL 6312/C3VL0241 is suitable for ABB M3BP and Siemens 1LE0/1PC series 90–160 kW VFD motors. High-frequency PWM easily induces fluting; TFL’s 3000 V-rated ceramic coating eliminates electrical erosion while maintaining full interchangeability with SKF INSOCOAT.
TFL 6312/C3VL0241 is recommended for Grundfos CRN, KSB Movitec vertical multistage pumps and 110–150 kW industrial centrifugal fans. The insulation remains stable even in humid, dusty and frequent start-stop conditions.
Urban rail and metro traction motors commonly use 6312 size can use TFL 6312/C3VL0241. The ceramic coating withstands complex electromagnetic environments and vibration in metro systems and has been verified in multiple metro maintenance projects.
