The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

It’s needed for most types of RepRap 3D printers. 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.

The SKF Premium quality, Versatile, and robust Deep Groove Ball Bearings are the most common bearing type found in a wide variety of applications. ZZ is equal to double metal shields one metal shield mounted on each side of the bearings and the bearings are lubricated for ensuring longer life.
