Single row cylindrical roller bearings, caged, mainly of the N,NU,NJ,NF,NUP and NFP designs
Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted. 
We offer premium cylindrical roller bearings under the LYNB brand names. Most LYNB cylindrical roller bearings feature case-carburized components. Rings and rollers are made from case-hardened alloy steel of “Bearing Quality” to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you’re looking for China-made, case-carburized inch series cylindrical, or a metric series through-hardened variety, LYNB has you covered with a proper fit to your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.
The LYNB range of single row cylindrical roller bearings comprises the basic types
The inner ring of bearings of the N design has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.
The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings. For manufacturing and maintenance reasons, the two outer ring flanges of large-size bearings of the NU design which are identified by a Drawing No. may not be integral but take the form of loose flange rings.
The outer ring of bearing of the NJ design has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction.
Bearings of the NF design have one flange on outer ring and two integral flanges on inner ring. This type of bearings can carry a certain amount of axial loads in single direction.
The outer ring of bearing of the NUP design has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.
Bearings of the NFP design have one flange a loose flange on outer ring and two integral flanges on inner ring. This type of bearing also can carry a certain amount of axial loads in double directions.
▲   The design’s of all these single row cylindrical roller bearings are based on standard structures; LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNB Technical Center if you need any assistance in this area.
