Descriptions of Imported bearings N219

Quick details of Imported bearings N219

 Cylindrical roller bearing are in many designs,dimension series and sizes.Bearings with a cage can accomodate heavy radial loads and operate at high speeds.Full complement bearings are suitable for very heavy radial loads at moderate speeds.This type of bearings is separable.
As their rollers lineary come into contact with inner ring and outer ring with less coefficient of friction,these bearings have very good capacity of radial load,suitable for electric motors,automobiles,transmission shafts,gear shafts and so on.Double row cylindrical roller bearings are good at the spindles of machine tools.

In bearing of this type, the cylindrical rollers  Bearing are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds.
There are different types designated NU, NJ, NUP, N, NF for single-row bearings, and NNU, NN for double-row bearings depending on the design or absence of side ribs.
The outer and inner rings of all types are separable.
Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.

Features of   Imported bearings N219
1 roller and raceway contact or repair offline contacts, radial load capacity, suitable to withstand heavy

 load and shock load. 
2 small friction coefficient, suitable for high speed, speed close to deep groove ball bearings.
3. N type and NU type can move axially, to accommodate misalignment due to thermal expansion or of 

the shaft and the housing due to changes in relative position, can be used for supporting the free end.
4 pairs of shaft or housing bore machining higher, bearing outer ring axis relative deflection after

installation should be strictly controlled to avoid contact stress concentration.
5 inner or outer ring detachable, easy installation and removal.

The structure of  Imported bearings N219

Cylindrical roller bearing is usually by a wall bearing rings of the two lead, Cage, and guide roller rings composed of a combination of things, the general type of bearing is detachable. Bearing this installation, the demolition of more convenient, especially when requested, and the outer shell and shaft are fit more shows its advantages. Bearing this kind generally used for radial load to bear, only, the outer wall with all the separate bearings can withstand axial loading smaller or larger batch of axial load. The same size and shape of the deep groove ball bearings, bearing with such a large radial load capacity of the structure from the point of view, also applies to high-speed rotation.

The usage of Imported bearings N219

Cylinderidal roller bearing and the raceway crown used it to design modification to eliminate the edge of the stress and improve bearing life.Bearing Cylindrical roller bearings
DF wall design of a certain angle, so the bearer of the axial load greater than the more conventional design for bearings

  Instruction of  Imported bearings N219

Cylindrical roller and the raceway is a linear contact,load capacity,able to withstand greater radial 

load and punch load,but also applies to high-speed rotation.Cylindrical Roller Bearing have a single row,double row,four-row and other deformation structures,which the single row Cylindrical Roller Bearing are most applicacable.

Cylindrical Roller Bearing is separable formed bearing,and convenient to be mounted and dismounter.Normally Cylindrical Roller Bearing can accommodate radial load only,none but single row bearings with ribs both on inner and outer rings can carry panial lighter axial load. 

  Characteristic of Imported bearings N219

1.High radial load capacity,is suitable for heavy load and impact load.

2.Small friction, suitable for high speed,the limiting Speed is close to Deep Groove Ball Bearings

3.N,NU series can adapt to high temperature and allow error during installation.

4.inner ring and outer ring are separable,easy to install and take down
