Single-Row Cylindrical Roller Bearings

Send Message Request a Quote

The single-row cylindrical roller bearing has several variants, which are mainly as follows:

1. Types N and NU without flanges in the outer ring or the inner ring
These two types of bearings can sustain heavy radial loads but cannot sustain axial loads. They have high speed limit and have no limit on the axial displacement of shaft or housings.

2. Types NF, NJ, NH (NJ HJ), and NUP with flanges in both the outer ring and the inner ring
Types NF and NJ of the single-row cylindrical roller bearing can restrict unidirectional axial displacement of shaft or housing. They can also sustain certain amount ofaxial loads in one direction. Differently, types NH and NUP can restrict bidirectional axial displacement of shaft or housing within the axial clearances and can sustain certain amount of bidirectional axial loads.
