Product description

The 1207K NTN is a double-row self-aligning deep-groove ball bearing. This type of bearing, which lacks a seal, consists of two rows housed in a spherical raceway in the outer ring. This design allows for self-alignment, meaning that misalignment of the shaft relative to the bearing housing does not impact performance negatively.

These features make the 1207K NTN appropriate for applications where significant misalignment or shaft deflections may occur. Additionally, self-aligning bearings have minimal friction compared to other rolling-element bearings, even at higher speeds, resulting in limited frictional heat. These bearings can accommodate high radial loads and, to a lesser degree, axial loads in both directions.
