⚙️ Features

Direct OEM Replacement: Perfectly matches CF Moto OEM part number 30400-01704 for precise fitment.
Standard Model 6203: Universal deep groove ball bearing widely used in engines, transmissions, and drive systems.
High-Quality Bearing Steel: Made from premium bearing steel with excellent wear resistance and long service life.
Precision Ground Raceways: Smooth raceways ensure low friction and quiet operation.
High Load Capacity: Designed to handle both radial and moderate axial loads in both directions.

✅ Importance of Bearing Replacement: Bearings are critical components that support rotating shafts and reduce friction. If a bearing wears or fails, it can cause shaft misalignment, increased noise, vibration, and eventual seizure, leading to severe engine damage. Common symptoms include: grinding noise, rough operation, shaft play, and overheating. During engine overhaul or when experiencing bearing-related symptoms, replace bearings with high-quality components.

⚠️ Installation Tips: Use proper bearing installation tools to press the bearing into place, avoiding impacts that could damage the bearing. Ensure the bearing bore and shaft are clean and free of burrs. Pack with appropriate grease if required.
