Cylindrical roller bearings high-speed rotation bear heavier radial load in very heavy duty medium-speed condition

Cylindrical roller bearings are mainly used in motors, machine tools, oil, mill loading and unloading machinery and industrial machinery.

Cylindrical roller bearings are separable bearings, installation and removal very easy. Divided into single row cylindrical roller bearings, double row and four columns.      

Cylindrical roller is lineal contact with the raceway, with high-load bearing capacity, which applies to heavy and shock load, at the same time withstand high speed rotation with N-type and NU type axial movement, adapt to thermal expansion or axis and shell relative changes caused by installation error. They are most suitable for the free end bearing NJ type and NF type, withstanding regular degree single-track axial load. NH type and NUP type can withstand regular degree both-way axial load in separation of inner ring and outer ring, which is convenient for installation and remove. NNU type and NN type have better radial load rigidity, usually used in machine tool principal axis.

  

 Major applicative retainer: steel plate stamping retainer (Z form), copper alloy cut-making retainer, melt form retainer, synthetic resin shaping retainer.

 

  Main application: medium-sized and high capacity motor, electric generator, internal-combustion engine, gas turbine, machine tool principal axis, reduction gear, loading and unloading movement machines, and all kinds of industrial machines, etc.

Rolling element bearings installed in accordance with the different number of columns, cylindrical roller shaft Commitment can be divided into single row, double row and multi-row cylindrical roller bearings. One application is more cage row cylindrical roller bearings. In addition, single row or double row full complement roller and other structures of cylindrical roller bearings.    

Single row cylindrical roller bearings under the ring ribs divided into N-type, NU type, NJ-type, NF-type and NUP type, etc.. Cylindrical roller bearings to bear the radial load capacity, according to the structure of ring ribs to withstand a certain one-way or two-way axial load.

NN and NNU type double row cylindrical roller bearings, compact structure, strong rigidity, load capacity, deformation under load is small, mostly used for machine tool spindle bearing. FC, FCD, FCDP type four-row cylindrical roller bearings can bear greater radial load, more for rolling mill and other heavy machinery

Cylindrical roller bearings: high-speed running can bear heavier radial load, a separate EC type cylindrical roller bearings designed to optimize the internal curve a can be improved radial and axial load bearing capacity, while improving on the angle and alignment errors and improve the lubricating ability to regulate the situation, omitted the full cage roller bearings can have a maximum number of rollers. In very heavy duty and medium-speed condition.      

N DesignInner ring has two integral flanges, the outer ring without flanges. Axis relative to the bearing of the axial displacement in both directions within the bearing in the bearing. Therefore, these bearings for non-locating bearing.

NU DesignNU design of bearing outer ring has two integral flanges, without inner flange. Axis relative to the bearing of the axial displacement in both directions within the bearing in the bearing. Therefore, these bearings for non-locating bearing. Because of the manufacturing and maintenance reasons, expressed in number of drawings of large bearing NU design, two outer flange is not necessarily integral, but will adopt the form of loose with the flange ring.

NJ DesignThere are two integral outer flange, an integral inner flange. Therefore, these bearings for shaft in one direction on the axial location.

NUP DesignThere are two integral outer flange, an inner ring and an integral flange with the flange ring loose form of non-integral flange. These bearings can be used as locating bearing, can provide shaft in both directions on the axial location.
