Interchangeable: Compatible with SKF/FAG models for a perfect replacement.
Electrical Protection: Breakdown voltage up to 3000V. Blocks stray currents to prevent electrical corrosion.
Plasma Spray Technology: Creates a coating with excellent wear and heat resistance.
Reliable Quality: Compliant with ISO 9001 and REACH standards. The production process is fully traceable.
TFL 6324M/C3VL0241 corresponds to SKF 6324 M/C3VL0241 and FAG 6324-M-J20AA-C3 in base dimensions and application direction, with a standard size of 120 mm bore, 260 mm outside diameter, and 55 mm width. This model uses a brass cage and C3 clearance, making it suitable for larger motors, generators, and VFD-driven systems. For replacement, mounting dimensions, cage material, clearance, speed, load, and insulation level should be checked together. It can be used as a reference in an INSOCOAT Equivalent Chart, SKF/FAG Interchange List, and direct replacement selection.

TFL applies plasma spray coating to create an alumina ceramic insulation layer on the bearing outer ring, helping reduce the risk of shaft-current damage in motor bearings. We support OEM/ODM, No MOQ, Fast Delivery, and engineering selection discussions for imported bearing replacement, spare-part purchasing, and batch projects. Under an ISO 9001 Certified quality system, TFL manages production and inspection to maintain dimensional interchangeability while helping customers control purchasing cost and total maintenance cost.
Verified standard dimensions — 120 mm bore, 260 mm outside diameter, 55 mm width.
Machined brass cage — suitable for large-size motor bearings and continuous operation.
High Dielectric Strength — breakdown voltage up to 3000 V DC.
TFL 6324M/C3VL0241 is exclusively designed for “heavy-weight” industrial scenarios simultaneously facing extreme physical loads and strong stray currents. Typical applications cover main drive motors for mining crushers and ball mills, heavy steel continuous rolling mill drives, MW-class marine electric propulsion systems, and large high-pressure water transport pumps. Its massive 260mm OD 63 series structure combined with a brass cage serves as a hardcore safeguard for the long-cycle, trouble-free operation of heavy machinery in harsh environments.
TFL electrically insulated deep groove ball bearing 6324/C3VL0241 can be used in high-power VFD-driven motor and generator systems such as Siemens 1LE0001 and ABB M3BP series. In these systems, high-frequency voltage from the inverter may create shaft currents, causing raceway erosion and increased vibration. TFL’s alumina ceramic outer-ring insulation provides up to 3000 V DC protection while maintaining the standard 120 × 260 × 55 mm mounting size, making it a suitable replacement option for SKF INSOCOAT and FAG J20AA types.
TFL 6324/C3VL0241 can be used in VFD motor bearing positions for Grundfos CR multistage pumps, KSB Eta centrifugal pumps, and large industrial fan systems. Pumps and fans often run continuously in humid and vibration-prone environments, while variable-speed control increases exposure to electrical disturbance. TFL’s outer-ring insulation provides voltage protection while keeping standard dimensional interchangeability for these equipment types.
In wind power applications, TFL 6324/C3VL0241 can be considered for similar bearing positions in generator or auxiliary drive systems such as Vestas V90, Goldwind GW121/2500, and Siemens Gamesa 2.3 MW turbines. Wind turbine equipment faces variable load, humidity, temperature change, and electrical disturbance, so bearing insulation can affect maintenance intervals and downtime risk. TFL’s plasma spray coating on the outer ring can be evaluated for these systems, especially where dimensional interchangeability, dielectric protection, and spare-part cost all matter.
