Large-Bore Medium Series — 130 x 230 x 40 mm dimensions, built to withstand substantial radial loads.
Plasma-Sprayed Insulation — High-bond alumina outer coating ensuring breakdown voltage up to 3000 V DC.
Machined Brass Cage (M) — Delivers superior durability and dampening under high vibration and mechanical shock.
TFL 6226M/C3VL0241 is exclusively developed for extreme heavy-industrial scenarios facing massive loads, strong mechanical vibrations, and complex high-frequency VFD interference. Typical applications cover heavy-haul AC traction motors in rail transit, MW-class marine electric propulsor main shafts, main drives for metallurgy rolling mills, and large high-pressure centrifugal pumps in mining and chemical plants. With the physical toughness of the brass cage and the electrical isolation barrier of the alumina coating, it serves as the reliable cornerstone for the long-cycle, trouble-free operation of heavy machinery.
In AC traction motors for heavy-haul freight locomotives by CRRC or Alstom, the equipment must directly confront severe mechanical shocks caused by uneven tracks and high-torque startups. Simultaneously, traction inverters generate high-frequency common-mode voltages. TFL 6226M/C3VL0241 employs a machined brass cage that perfectly withstands these destructive mechanical vibrations, while its 3000V outer-ring breakdown-resistant coating entirely cuts off the shaft current loop. It is a highly recommended alternative to enhance safety redundancy during traction motor overhauls.
In podded electric propulsors like Wärtsilä or ABB Azipod used on modern ocean research vessels and large LNG carriers, the main shaft support bearings must continuously handle massive propulsion torque and inverter harmonic interference. TFL 6226M/C3VL0241 is widely used as a critical support node for such MW-class drive motors. The brass cage provides high-strength rotational guidance under complex wave flow fields, while the outer-ring insulation guarantees absolute electrical isolation of the marine power system, ensuring foolproof ocean navigation.
In high-flow VFD centrifugal pump sets by Sulzer and Flowserve used in deep mine dewatering or chemical plants, fluid pulsations and rotor imbalance trigger intense low-frequency vibrations. TFL 6226M/C3VL0241 effectively supports the massive rotor with its 130mm heavy-duty cross-section, while the brass structure significantly reduces metal fatigue risks. Its VL0241 coating cuts off electrical damage caused by high-frequency PWM drives at the source, substantially extending the service life of both the pump’s grease and the overall equipment.
