Product Description

Product Description

Cylindrical Roller Bearings are designed to handle radial load at high performance and speed. According to the presence or absence of ribs, it can be divided into NU, NJ, NUP, N, NF, NH and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings.

The bearing has a separable inner ring and outer ring structure.Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.

 

Product Parameters

Technical specification

Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings. Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
 

Types NU, N, NNU, and NN are suitable as free-end bearings. 
Types NJ and NF can sustain limited axial loads in one direction.
Types NH and NUP can be used as fixed-end bearings.
NH-type cylindrical roller bearings consist of the NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars.
The inner ring loose rib of an NUP-type cylindrical roller bearing should be mounted so that the marked side is on the outside.
