TFL 6226/C3VL0241 is a 100% equivalent and direct replacement for large-size insulated bearings from SKF and FAG in terms of mechanical dimensions (130x230x40mm), standard pressed steel cage structure, C3 clearance, and VL0241 outer-ring physical properties. Customers do not need to perform any secondary machining on existing motor shafts or housings during equipment maintenance. All outgoing products pass strict voltage resistance testing (>1000V DC) and dimensional precision checks.

Large-Bore Medium Series — 130 x 230 x 40 mm dimensions, offering robust radial load support.
Standard Pressed Steel Cage — Lightweight and highly efficient, optimized for low running friction.
Stable Electrical Resistance — Maintains 50–200 MΩ to completely block destructive stray currents.
TFL 6226/C3VL0241 is widely applied in large VFD drive equipment operating under standard, smooth industrial loads. Typical applications encompass large horizontal water transport pumps in municipal water systems, industrial centrifugal fans in chemical plants, high-power AC motors in general manufacturing, and large commercial HVAC centrifugal compressors. Its standard steel cage structure is ideal for steady-state continuous high-speed operation, while the reliable outer-ring insulation perfectly cuts off high-frequency electrical loops introduced by MW-class VFD systems.
In general high-power industrial VFD motors like the Siemens 1LE1 or ABB M3BP series, high-frequency PWM signal interference often causes rotor shaft currents to break down the lubricating oil film. TFL 6226/C3VL0241’s steel cage design is lightweight and low-friction, perfectly suited for medium-high speed continuous and smooth operation. Its outer-ring 3000V alumina insulation provides excellent anti-erosion protection, making it a highly cost-effective SKF INSOCOAT alternative for MRO in such large motors.
In large VFD horizontal centrifugal pumps by Flowserve and Grundfos widely used in municipal water supply and power plant cooling systems, equipment often requires uninterrupted operation for months. Utilizing TFL 6226/C3VL0241 as a critical support bearing, its C3 clearance fully adapts to the temperature rise of the 130mm large bearing during full-speed runs, while effectively cutting off electrical erosion leakage caused by inverter harmonics, drastically extending the time interval between pump overhauls.
At the main drive ends of centrifugal compressors by Atlas Copco or Trane in large chemical plants or commercial buildings, high-speed rotation and high-power VFDs easily trigger intense common-mode shaft voltages. TFL 6226/C3VL0241 provides stable support with its 130mm bore and 50–200 MΩ insulation resistance, efficiently isolating high-frequency interference currents. This ensures the compressor raceways are safe from arc flaking threats, improving the overall uptime of the energy production line.
