Description

Double row cylindrical roller bearings, caged, mainly of the NN, NNU, and NNF 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 LYNBC brand names. Most LYNBC 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, LYNBC 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 LYNBC range of double row cylindrical roller bearings comprises the basic types.

Double row cylindrical roller bearings have a low cross section, high load carrying capacity and high stiffness. Therefore they are mainly used in machine tools, rolling mill stands, plastic calenders, grinding mills and also large gearboxes.

LYNBC produces double row cylindrical roller bearings mainly in the NN design and the NNU design. The bearings are separable, i.e. the ring with integral flanges together with the roller and cage assemblies can be mounted separately from the other bearing ring or all bearing components can be mounted separately. This facilitates the mounting, inspection and maintenance of these bearings. Double row cylindrical roller bearings are produced with both cylindrical bore and tapered bore; bearings of the NN design are generally supplied with tapered bore. When mounting bearings with tapered bore it is possible to achieve a certain radial internal clearance or a given preload.

Bearings of the NNF design are one kind of double-row cylindrical roller bearings full of rollers which is consist of outer ring with a center flange two inner rings with double flanges. Rollers are guided by flanges on inner ring and two inner rings are fixed up by fastening ring. This structure can carry not only a lot of heavy radial load and axial load but also tilting moment. Therefore they are suitable to be used as non-locating bearings. Bearings of type NNF have contact seals at two sides. And it is filled in grease lubricant. The working temperature would be -50℃~+110℃.However after considering of seal material available working temperature shall be -40℃~+80℃. Under appropriate conditions sealed NNF bearing need little maintenance and could be kept long time in water vapor or polluted environment. When mid or high speeding bearing can got make-up lubricating through lubrication groove and bore.

▲ The design’s of all these double row cylindrical roller bearings are based on standard structures; LYNBC 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 LYNBC Technical Center if you need any assistance in this area.
