634 ZZ Mini Ball Bearing 4x16x5 Shielded

634 ZZ ball bearing is a small rolling bearing that uses balls to separate two “races” or bearing rings. The main difference between these bearings and many others is their small size, allowing them to be used in smaller and more compact light-duty applications.

The combination of balls and bearing rings helps reduce surface contact and rotational friction on the plane of motion to accommodate axial loads.

Ball bearings play an important role in facilitating smooth and efficient motion in high-speed applications. It also help to extend the life of equipment. They are also effective space savers in compact applications.

● ISO standard interchangeable dimensions

● Electric Motor Quality (EMQ)

● Shield(s) provides some contamination protection and lubricant retention

● Used in high speed applications like electric motors
