We can provide 6207 with three type design ,in an open, shielded (ZZ), or sealed (2RS) design.
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.
Below here is two type of KOYO bearing color box packing for your reference .
KOYO 6207 bearing is applied to precision instruments, low noise motors, automobiles, motorcycles and general machinery industries. It is the most widely used kind of bearings in machinery industry.
