Enhanced Thermal Compensation: C4 internal clearance allows for significant thermal expansion in high-temperature motor operations.
Superior Electrical Isolation: Specialized VL0241 ceramic coating on the outer ring blocks stray currents and prevents raceway damage.
Perfect Brand Interchangeability: Seamlessly replaces SKF 6317/C4VL0241 and FAG 6317-J20AA-C4 in existing systems.
Tested Reliability: Every unit is dielectric-tested to withstand at least 1000V DC, ensuring consistent insulation performance.
TFL offers a high-quality, cost-effective alternative to premium manufacturers like SKF, FAG, and NKE for the 6317/C4VL0241 specification. TFL ensures faster global delivery and flexible minimum order quantities. Within the same series, choices like the 6317/C3VL0241 or the brass cage 6317M/C4VL0241 are also available to suit specific mechanical requirements.

TFL excels in the precision engineering of current-insulated bearings, utilizing advanced plasma-spray coating techniques. The 6317/C4VL0241 model undergoes rigorous quality control to ensure the aluminum oxide layer remains consistent and durable under stress.
Plasma-Sprayed Al2O3 Coating: Provides a high-resistance barrier on the outer ring, blocking currents up to 1000V.
Interchangeable Design: Standardized dimensions (85x180x41 mm) allow for immediate drop-in replacement in any standard motor housing.
C4 Radial Internal Clearance: Designed for applications with high temperature gradients between the inner and outer rings.
The 6317/C4VL0241 is indispensable for heavy-duty electric motors where both electrical isolation and heat management are critical. While we also provide the 6317/C3VL2071 for inner-ring insulation needs, the C4 outer-ring version is a staple in high-demand industrial sectors.
Large-scale industrial ventilation systems in steel mills or glass factories rely on motors that run at high temperatures. Brands like Ziehl-Abegg and EBM-Papst incorporate 6317/C4VL0241 bearings in their large-drive fan motors. The bearing ensures the shaft remains grounded and free from electrical pitting even as the motor housing reaches extreme operating temperatures.
In the mining sector, variable speed drives are common for crushers and conveyors. ABB's M3BP and M3GP series motors, often used in harsh mining environments, utilize the 6317/C4VL0241 to prevent shaft currents caused by VFDs. The C4 clearance is vital here as these motors often operate under heavy loads that generate significant internal heat.
Large electric motors driving circulation pumps in thermal power plants face continuous duty cycles. Manufacturers such as Sulzer or Flowserve specify the 6317/C4VL0241 for motors in these high-reliability environments. The insulation prevents bearing failure due to stray currents from the plant’s power distribution system, while C4 clearance handles the continuous thermal load.
