The 624ZZ bearing is a popular item that can be used in many applications. It's needed for most types of Reprap 3D printers. Each bearing has 2 metal shields, one shield on each side. Our bearings come pre-lubricated from the manufacturer so that no additional lubrication is required to be applied. These protect the bearing from dust or any possible corrosion.
Bearings come in various qualities. We have carefully selected the best quality bearings from numerous suppliers. This means our bearings are meant for continuous use and they'll last longer than other cheap bearings. Ideal for use in your 3D Printer, CNC project or robot.
