6203 – Deep groove ball bearing

The 6203 bearing is a widely-used single row deep groove ball bearing known for its versatility and durability across various applications. Typically featuring dimensions of 17 mm bore diameter, 40 mm outside diameter, and 12 mm width, it offers a compact yet robust solution capable of handling both radial and axial loads effectively. Depending on the specific application requirements, the 6203 bearing is available in different sealing configurations including open, rubber seals (RS), or metal shields (ZZ), providing options for varying levels of protection against contaminants such as dust and moisture. This flexibility in sealing helps ensure reliable performance and extends the bearing’s operational lifespan in diverse environments. Constructed with a pressed steel cage, the 6203 bearing maintains proper ball guidance under load, supported by its normal radial internal clearance which facilitates smooth operation under typical conditions. Lubricated with grease, it operates efficiently within a temperature range typically spanning from -30°C to +120°C, making it suitable for use in electric motors, automotive components, machinery, home appliances, and agricultural equipment.
