The 6403 Single-row deep groove ball bearings mainly consist of an inner ring, outer ring, steel balls, and a cage. The raceways are deep grooves, with the steel balls making four-point contact with the raceways. The inner and outer rings can be separable or integrated. They are available in various forms, including open, with dust covers, and with seals.

Single-row deep groove ball bearings have a simple structure and are the most widely used. They can simultaneously withstand radial loads and bidirectional axial loads, making them suitable for high-speed operation. They have a low coefficient of friction, low noise, and are easy to install and maintain. Versions with seals or dust covers effectively prevent contaminant intrusion and are suitable for various operating conditions.
