China 6002-2RS Deep Groove Ball Bearings 15x32x9mm

Simple Design, be convenient when use.Advantage: Low Friction coefficient; High limit speed.
Bearings are supplied in an open, shielded (ZZ), or sealed (2RS) design.
Many sizes are also available with a snap ring installed on the bearing's outer ring.

Open bearings are supplied with a light oil coating and are used in oil bath and oil misting applications.
Sealed bearings are supplied with a contacting lip seal that excels in protecting the bearing from liquids and other foreign contaminants. The inherent design creates friction, drag, and in turn heat; factors that require consideration in high speed applications.
Shielded bearings are provided with non-contacting metal shields that protect against larger particles entering the bearing, but do not protect against liquids. They add no friction during operation and therefore do not generate heat build-up.
