The Shielded Bearing 606 ZZ C0 is a type of Deep Groove Ball Bearing that is commonly used in applications that require high speed and low friction.
The "606" refers to the bearing's specific dimensions, with a bore diameter of 6mm, an outer diameter of 17mm, and a width of 6mm.
The "ZZ" indicates that the bearing is shielded on both sides. This type of shield is made from metal and helps to prevent dust, dirt, and other contaminants from entering the bearing and causing damage or reducing its lifespan. However, it allows for some minimal lubrication leakage.
The "C0" refers to the bearing's internal clearance, which is the amount of space between the balls and the raceways. C0, or 'normal' clearance, is suitable for most applications where temperature, speed, and load conditions are normal.
This type of bearing is often used in applications such as small motors, skateboards, and other types of machinery where high speed, low friction, and durability are important.
