6304 ZZ - Ball bearing 20x52x15 mm

The Pedrollo 6304 ZZ ball bearing is an original spare part for Pedrollo electric pumps.

The bearing supports and guides the rotating shaft of the electric motor, maintaining its proper alignment and allowing it to rotate with very little friction. In an electric pump, this contributes to the proper functioning of the motor, shaft, and impeller assembly.

In the name of the bearing can be divided into 2 parts: 6304 and ZZ.

6304 is a deep groove ball bearing in the 63 series. It is particularly suitable for electric motors because it offers low friction, high speed capability, and the ability to support radial loads along with axial loads in both directions. It can accommodate primarily radial loads, but also a component of axial load in both directions.

ZZ means the bearing has metal shields on both sides. It's not waterproof; it has double metal shields.

Since it is shielded on both sides, it belongs to the family of closed bearings with grease inside. It does not require periodic relubrication.
