Manufacturer designation:

BB1-0078 SKF

Design:

The ball bearing consists of two rings (internal and external) and rolling elements (balls), connected with a cage - separator, have a low coefficient of friction and are optimized for low noise and vibration, which ensures high rotational speeds. 

Features:

Closed on both sides with RS type metal-plastic seals.
They can withstand radial and axial loads in both directions.
Low friction coefficient and high rotational speed.
