Machined Brass Cage Durability: Equipped with a robust “M” type brass cage, the 6217M VL0241 bearing withstands higher vibrations and operational speeds compared to pressed steel variants.
Direct Interchangeability: Precise dimensions (85x150x28mm) make this a seamless Replacement for SKF 6217M/C3VL0241 and other major brands without machine modification.
Versatile Model Options: While the 6217M features a brass cage, our series also includes the steel cage 6217/C3VL0241 and the larger clearance 6217M/C4VL0241 to match specific motor requirements.
Superior Al2O3 Coating: Plasma-sprayed ceramic layer ensures long-term dielectric strength.
TFL’s 6217M/C3VL0241 is engineered to strictly match the dimensional and performance standards of premium global manufacturers. While functioning as a technical equivalent to the SKF 6217M/C3VL0241 or the FAG 6217-M-J20AA-C3, the TFL alternative provides significant advantages in supply chain efficiency. Global B2B buyers benefit from more competitive pricing structures, flexible Minimum Order Quantities (MOQ) that accommodate both prototype and bulk needs, and expedited logistics that reduce downtime. Furthermore, TFL offers customization on insulation voltage ratings that many standard catalog options do not provide.

TFL represents a reliable hub for Insulated Motor Bearings. Unlike generic bearing suppliers, TFL employs rigorous 100% spark testing on every coated outer ring to ensure zero pinholes and guaranteed dielectric strength. Our utilization of high-grade vacuum-degassed steel combined with precision-machined brass cages ensures that the mechanical integrity matches the electrical protection.
Robust Brass Cage (M Suffix): The solid machined brass cage provides superior resistance to shock loads and vibration compared to steel cages, making the 6217M VL0241 ideal for heavy-duty industrial motors.
Advanced Plasma Coating: The outer ring features a 50-500μm ceramic oxide layer (VL0241 specification) that provides electrical resistance > 50 MΩ at 3000V DC, effectively stopping shaft currents.
Precision Geometries: Manufactured to P5/P6 precision classes, ensuring low noise operation and perfect alignment, serving as a drop-in Replacement for SKF 6217M/C3VL0241.
The 6217/C3VL0241 is primarily engineered for medium-sized electric motors where inverter-driven stray currents threaten bearing longevity.
Within the general manufacturing sector, the 6217/C3VL0241 is a staple for ABB M3BP series or Siemens 1LE1 series motors used in conveyors and heavy fans. These motors, when controlled by Variable Frequency Drives (VFDs), frequently experience voltage spikes that cause bearing discharge. By installing the 6217/C3VL0241, plant engineers prevent “fluting” marks on the bearing raceways, significantly extending the Mean Time Between Failures (MTBF).
The precision and reliability of the 6217/C3VL0241 are vital in textile spinning machines and paper calendering rolls, such as those from Andritz or Voith. These machines require constant, high-speed rotation where any electrical interruption or bearing seizure can lead to massive production losses. For environments with higher mechanical vibrations, TFL recommends the 6217M/C3VL0241 variant to provide extra cage durability alongside its insulation properties.
In the renewable energy sector, the 6217/C3VL0241 is often integrated into the pitch and yaw drive motors of wind turbines from brands like GE Renewable Energy or Gamesa. These motors adjust the blade and nacelle positions and are exposed to atmospheric electrical discharge and inverter-induced currents. Utilizing the 6217/C3VL0241 (or the 6217M/C4VL0241 for extreme temperature swings) ensures the turbine remains responsive and avoids the high costs of offshore or high-altitude maintenance.
