The 6203 bearing is one of the most popular deep groove ball bearings, widely used in electric motors, household appliances, automobiles, and industrial machinery. It is known for its compact size, high precision, and smooth operation, making it suitable for both high-speed and high-load applications.
Categories: 6200 Series Bearings
The 6203 bearing typically consists of an inner ring, an outer ring, spherical rolling elements, and a cage. Its raceway groove is slightly larger than the radius of the steel balls. Due to the point contact between the steel balls and the raceway, it can withstand both radial and bidirectional axial loads. It is usually used in pairs to utilize radial load to reduce internal axial force.
The 6203 bearing is made of high-quality steel (GCr15), offering excellent durability and precision.
It can withstand high-speed rotation and light to medium axial and radial loads.
It features low friction, low noise, and low vibration.
The 6203 bearing is commonly used in automotive, industrial machinery, and agricultural equipment.
The 6203 bearing offers high speed, high load capacity, and excellent durability, supporting the operation of mechanical equipment and maintaining high efficiency and reliability under various harsh environmental conditions.
The 6203 deep groove ball bearing is a versatile and durable bearing designed for smooth and reliable performance. With a bore of 17 mm, outer diameter of 40 mm, and width of 12 mm, the 6203 bearing fits a wide range of electric motors, household appliances, and industrial machinery.
