603ZZ 3x9x5 Deep Groove Ball Bearing

Single-row ball bearing is one of the most important elements of the drive unit, for universal applications, including modeling engines and construction, e.g. CNC.
Ball bearing type 603ZZ. Deep groove ball bearings are a very popular type of rolling bearings used to achieve smooth, harmonious and very quiet rotation.

A bearing is a machine element used to seat shafts and axles in supports. This type of bearing consists of four basic elements:

Inner ring
Rolling element
Ball basket

Attention! It is worth checking the condition of bearings in each motor, it is especially recommended to control the quality of the motors' operation. A damaged bearing is a source of vibration, which can cause many problems.

Miniature bearings found in modeling engines are one of the most important elements of the drive unit. We owe them the high quality of engine operation. The most common are deep groove roller bearings.
