[angular contact ball bearing, cylindrical roller bearing]
As a professional angular contact ball bearings, cylindrical roller bearings manufacturer, exporter, supplier and factory in China.--China Ningbo XLBearings Limited. have advanced equipment and precision test apparatus, from designing, purchasing, producing, packing, storing to delivering, the whole procedure under the ISO9000 quality assurance standards system competely.
Angular contact ball bearings
When the single-row angular contact ball bearing is carrying the radial load, there will be a component of force in the axial direction.Therefore it is suggested that two of these bearings be applied in back-to-back or face-to-face arrangement.
These bearings have contact angles between the rings and balls. The standard angles are 15°、25°、and 40°.The greater the angle, the higher the axial load carrying capacity of the bearing. However, the smaller contact angle, the higher the rotating speed.
Single row bearings can carry radial load and axial load in one direction.
Double-row angular contact ball bearings have two designs of one outer ring and two inner rings and one outer ring and one inner ring. For the design with one outer ring and two inner rings, the axial clearance is easy to control during machining.
Angular contact ball bearings are applied for high speed and high precision rotating condiations.
These bearings are mainly applied in the machine tool spindles,high-frequency motors, gas turbines, oil pumps,air compressors, printing machines and other installations.

With low noise and stability, XLB bearings, angular contact ball bearing, cylindrical roller bearing can be used in mirco-dynamo, automobile, telecommunication devices, instrument and motors, medical apparatus computer and office equipment, they has been accepted within twenty countries by higher quality, by competitive price, by good service up to date, their track covered Europe, the South America, the North America, Aisa and Africa and she enjoys a good reputation in the Bearings trade world all time.Wish communicate information and operator business with you in short future, beside our main products, angular contact ball bearings, cylindrical roller bearings, we can collect various kinds of other Bearings for you. let's work hard for it sincerely.
Cylindrical roller bearings
Cylindrical rollers have linear contact with the raceway,and the bearings can carry heavier load. Applications are found in situations characterized by heavy load and shock load and also high rotation speed.
The N type and NU type bearings can be movable along the shaft. They can adapt the position changes between the shaft and housing caused by the thermal expansion or the mounting erro and are most suitable for free end shafts.
NJ and NF types can accept certain axial load in one direction, and NUP type can accept certain axial load in two directions.
Inner ring and outer ring can be separable, and they are conbenient to mount and dismount.
The rigidity in carrying radial load in the NNU and NN types make them applicable for machine tool spindles.
FC, DCD and FCDP type can carry comparatively heave radial load and are mainly applied for mill rolls.
Applications of these bearings are mostly found in middle-sized and large-sized motors, electricity generators, internal comubustion engines,machine tool spindles, decelerarion devices, unloading and lifting machines and other industral machines.
Single-row cylindrical roller bearings
NU type and N type cylindrical roller bearings allow the shaft to move in the axial direction within certain limits in relation to the housing. Therefore, they can be used as bearings on the r\free end of the shaft.
NJ type cylindrical roller bearing can carry the axial load within certain limies in double directions.
Double-row cylindrical roller bearings
There are cylindrica bored and taper bored cylindrical roller bearings. There may be lubricating holes or groovws on the outer rings of these bearings.
Mostly these bearings are used in machine tool spindles, but they can be used in other situations too.
Four-row cylindrical roller bearings
Four-row cylindrica bored and taper bored cylindrical roller bearings can carry much heavier radial load and shock load.
They have higher manufacturing percision and can be ysed to meet high rotational speed requirement. Mostly these bearings are used in the rolling mills and some other cases.
