603 2RS Miniature Bearing 3x9x5
Rubber seals on the 603 2RS ball bearings keep out dirt etc. This also helps preserve the lubricant. These deep groove ball bearings are versatile, durable and relatively easy to maintain.
This series is a very popular bearing with a wide range of applications. They are simple in design, inseparable, suitable for high speeds and run robustly, requiring little maintenance. The deep raceway grooves and the tight fit between the raceway grooves and the balls enable the deep groove ball bearings to withstand not only radial loads but also bidirectional axial loads.
603 2RS miniature bearings are widely used in industrial and scientific applications such as medical and industrial handpieces, flow meters, fuel control, gyroscopes, synchronizers, servo systems, electric motors, cryocoolers, pulmonary assist equipment, etc.
