3304 B ZZ-C3 - Ball bearing 20x52x22.2 mm

The Pedrollo 3304 B ZZ-C3 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 4 parts: 3304, B, ZZ and C3.

3304 indicates that it is a double row angular contact ball bearing, with a 20mm bore.

B concerns the internal geometry at contact angle.

ZZ refers to the two metal shields, one on each side. They generate less friction and are particularly suitable when maintaining good rotation speeds is important.

C3 indicates an internal clearance greater than the normal clearance. This is particularly important in applications where temperature, speed, and coupling can reduce the effective clearance during operation.

Unlike 62 series bearings, the 3304 B ZZ-C3 bearing, with its double row of ball bearings and angular contact raceways, is specifically designed to accommodate combined radial and axial loads. The double row configuration also allows for axial support in both directions.

Original spare part for TR 1.5 and TR 2.2.

The outer diameter is 52 millimeters while the inner diameter is 20 millimeters, the width is 22.2 millimeters.
