Features

• Dual-Sided Rubber Seals (2RS): Double synthetic rubber contact seals effectively lock in essential grease lubrication while completely blocking outside dirt, road grime, and water.  
• High-Speed Optimization: Designed to run seamlessly at high rotational speeds up to 8,400 RPM with minimal internal heat generation.
• Heavy Load Support: Built with high radial and moderate axial load-bearing capacities to easily sustain passenger and cargo weight in electric commercial vehicles. 
• Low Noise & Vibration: Precision-ground raceways and high-accuracy steel balls drastically lower friction, vibration levels, and operational sound.  
• Corrosion & Wear Resistance: Finished with highly polished, heat-treated steel rings that resist surface pitting and structural deformation over long operational cycles.

Applications

• Primary installation in front and rear wheel multi-hubs of commercial passenger and cargo E-rickshaws.
• Integration into electric vehicle (EV) BLDC motors, mid-drive powertrains, and reduction gearboxes.  
• Standard axle and differential units for battery-operated three-wheelers and electric loaders.
• Suitable for universal industrial machinery, electric power tools, pumps, and agricultural machinery matching the 6205 dimension profile.

Usage

Maintenance

• The 2RS configuration is fully sealed and permanently pre-lubricated for life; it does not require any manual grease refilling or relubrication.  
• Routinely check the wheel hub assembly area for signs of external rubber seal punctures, physical cracks, or deep grease leakage.
• Check for early warning signs of wear, such as unnatural wheel wobbling, elevated structural vibrations, or rough grinding noises while the vehicle is moving.
• Replace the component promptly if the vehicle is exposed to deep floodwater immersion or severe impact forces that could deform the internal metal raceways.
