Bearing Type:

Japan NSK 542 6907DU or DDU


This is a 6900 series bearing which makes it a "single row ball bearing - thin section" with the 7 representing "7 multiples of 5mm" or having a 35mm inside diameter.

The DU designates a "single seal", or in other words, one side has a seal, the other does not. A DDU would designate "double seal", meaning both sides a have seal. Based on different findings it appears that the factory have used both types in production with the "double seal" type being the preferred choice.

Note that seal designations vary based on manufacturer.
