TFL 6318M/C3VL0241 is fully equivalent to SKF, FAG, and other mainstream INSOCOAT bearings in dimensional tolerances, heavy-load capacity, and dielectric properties. Its standardized outer-ring ceramic coating and machined brass cage ensure a plug-and-play direct replacement without modifying existing equipment structures. Every dispatched bearing passes strict voltage resistance tests, providing strong support for cost reduction and efficiency improvement.

TFL specializes in the electrically insulated bearing sector, utilizing leading plasma-spraying technology to create a uniform and dense high-purity alumina ceramic coating on heavy-duty bearing outer rings. As an ISO 9001 certified manufacturer, we provide not only exceptional anti-erosion products but also full-cycle technical support. Whether you need OEM components or urgent MRO maintenance, TFL’s no-MOQ policy and fast delivery capabilities help you achieve cost savings while guaranteeing uncompromised quality.
Heavy-Duty 63 Series Design — Larger cross-section for maximum load-carrying capacity (Bore: 90mm, OD: 190mm).
Plasma Spray Alumina Coating — High-bond uniform ceramic layer (100–500 μm).
Machined Brass Cage (M) — Superior vibration damping and performance in marginal lubrication.
TFL 6318M/C3VL0241 electrically insulated bearings are widely used in mining machinery, metallurgical rolling mills, high-power VFD motors, and heavy industrial pumps. These environments frequently face massive radial loads, intense shock vibrations, and shaft voltages generated by high-frequency inverters. With its robust brass cage and 3000V insulation, this model is the premier choice for enhancing equipment stability in extreme heavy-industrial scenarios.
TFL 6318M/C3VL0241 is suitable for ultra-high-power VFD motors such as the Siemens 1LE0001 and ABB M3BP series. In these machines, heavy loads and inverter harmonics often cause both mechanical and electrical failures in standard bearings. TFL’s brass cage and alumina ceramic insulation provide reliable protection while maintaining standard interchangeability, making it a recommended alternative to SKF INSOCOAT heavy-duty equivalents.
In VFD-controlled heavy centrifugal pumps by Sulzer and KSB used in mine dewatering or chemical plants, fluid pulsation and imbalance cause severe vibrations. TFL 6318M/C3VL0241 is highly recommended for the non-drive end of these units. The solid brass structure resists mechanical fatigue, while the VL0241 outer-ring insulation effectively cuts off the shaft current loop, preventing premature grease degradation.
In the wind power sector, TFL 6318M/C3VL0241 can be applied in the yaw or generator drivetrains of MW-class turbine systems like Vestas and Siemens Gamesa. Such applications endure variable loads and must withstand electrostatic and stray current shocks. TFL’s coating resists up to 3000 V with extreme hardness, making it a recommended insulated, long-life solution for wind turbine overhauls and the MRO market.
