6303 2RS-C3 - Ball bearing 17x47x14 mm

The Pedrollo 6303 2RS-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 3 parts: 6303, 2RS and C3.

6303 is a deep groove ball bearing in the 62 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.

2RS indicates that the bearing is sealed on both sides by elastomeric and rubber seals. These seals retain the lubricating grease and provide superior protection from dust, dirt, and contaminants.

This makes the 2RS configuration particularly interesting when the bearing operates in an environment more exposed to contamination.

C3, on the other hand, indicates a greater internal radial clearance than normal. The increased clearance is intentional and serves to compensate for operating conditions in which the actual clearance tends to decrease, for example due to assembly interference and thermal expansion.

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