Product Description

The 1203SC3 NTN is part of the double-row self-aligning deep-groove ball bearings category. This type of bearing, without a seal, features two rows housed in a spherical raceway within the outer ring, allowing for self-alignment. Consequently, any misalignment of the shaft relative to the bearing housing does not negatively impact performance.

These attributes make the 1203SC3 NTN ideal for applications where considerable misalignment or shaft deflections may occur. Additionally, self-aligning bearings possess the lowest friction among all rolling-element bearings, ensuring limited frictional heat even at higher speeds. These bearings are designed to handle high radial loads and, to a lesser extent, can support axial loads in both directions.
