6004 AV NILOS metal seal 20x37,8x2

Application for protection of ball bearings

6004 AV NILOS is a precision metal seal designed to protect 6004 ball bearings against contamination and grease loss. The thin steel sealing ring forms an additional barrier between the bearing and the surrounding environment, increasing the operational reliability of the entire bearing unit.

In industrial applications the 6004 AV NILOS metal seal is used in electric motors, gearboxes, conveyor systems and production machinery. Installed between the ball bearing and the bearing housing, it limits the ingress of dust, metal particles and other contaminants. This contributes directly to high durability and stable operation under continuous load conditions.

Design and operating principle

The 6004 AV NILOS metal seal is manufactured from precision formed steel sheet with a ring thickness of 0,3 mm. The AV type is intended for use with a single side open deep groove ball bearing. The sealing ring contacts the inner ring shoulder, reducing contamination entry into the rolling element area.

Compared to rubber seals, a metal seal offers minimal friction torque and high dimensional stability at elevated operating temperatures. It is particularly suitable for high speed applications where low resistance and long service life are required.
