what is roller bearing

Last time we talked about what is ball bearing,according to elements,we divided into ball bearing and roller bearing,meanwhile we introduced many kinds of ball bearing,the design of the cage and the material of ball bearing,and today we learn what is roller bearing together,the charactor of ball bearing is high speed than roller bearings,but the better carry capacity of the roller bearings.

Roller bearing
*Cylindrical roller bearing
*Spherical roller bearing
*Needle roller bearing
*Tapered roller bearing
*Thrust roller bearing
*Carb toroidal roller bearing

1.Cylindrical roller bearing has single row,double row and four-row cylindrical roller bearing design,
Cage:brass cage, pressed steel cage,nylon cage 
N,NU,NUP,NJ different inner and outer ring design
single row cylindrical roller bearing are mainly used in machinery shaft,
so it has very high precision demand,four row cylindrical roller bearing mainly used in Rolling Mill Equipment,it has very high carry capacity

2.Spherical roller bearing also named self-aligning roller bearing,it has single row and double-row spherical roller bearing,sealed spherical roller bearing,in China,many person in bearing industry called this kind of bearing as three kind bearing,this type bearings have many kinds of cages design,
solid brass cage(CA,one piece,MB,Two pieces),and also the pressed steel cage (E,E1,EAE4, CC,CJ, CD design),TVP2,ECP nylon cage,its difficult to produce becuase of the raceway is the sphere shape, have some radian of the raceway,so it must be very high precision ,meanwhile the roller are also have sphere shape,the rollers and raceway of spherical roller bearing must be work closely with a reasonable point of contact in the bearing during operation.make sure each roller can share the press when the bearing working,improve the service life of the bearings extently,material:
 
chrome steel spherical roller bearing 
stainless steel spherical roller bearing

3.Needle roller bearing cannot carry so large capacity like the other roller bearings,becuase its roller is not so big as the cylindrical roller bearing,and also the thin inner ring and outer ring,so its character can used in very small space instead of cylindrical roller bearing ,needle roller bearing are widely used in Automotive industry

4.Tapered roller bearing is the most large production and used on the market, as one separable bearing,it have pressed cage,brass cage and nylon cage design,single-row & double-row and four row tapered roller bearing can meetthe market demand,material:
 
carbon steel tapered roller bearing
chrome steel tapered roller bearing

5.Thrust roller bearing consist of spherical roller thrust bearing,cylindrical roller thrust bearing,tapered roller thrust bearing,these kind of bearing can carry axial load,lower speed than the Radial bearings,
the cage can be brass or pressed steel design

6.Carb toroidal roller bearing,design and produced by EASIER bearing,this kind of bearing looks like spherical roller bearing and needle roller bearing,but not the same,it is thin of the inner ring and outer ring than spherical roller bearing,but thicker than needle roller bearing,the rollers is also barrer design , but thin and longer than spherical roller bearing,Carb toroidal roller bearing can make up the lack of spherical roller bearing and needle roller bearing,it have with cage and full-complement Carb toroidal roller bearing design.

Bearing for bucket wheel excavator

this biggest bucket wheel excavator with wonderful devices and compact design,in its front mounting with huge back wheel,the back wheel with a saw(diameter:12 meters), the total weight of the machine is 45,000 tons and a height of 45 meters,the same height with four storeys.the outermost edge of the machine is a series of spoon-like or Barrel device,at the completion of the loading and unloading of coal by belt.this machine has very strong  operational capacity,4500 tons coal mining per hour,it can clear away all obstacles in front of you,ever high mine mountain.

 
So this so big bucket wheel excavator must be used very high quality bearing,just like spherical roller bearing,deep groove ball bearing,cylindrical roller bearing,as one of China bearing manufacturer,XRB can supply EASIER spherical roller bearing,FAG Cylindrical roller bearing,TIMKEN tapered roller bearing to meet the high quality demand.

22216E bearing

Related bearing:SKF 22216E bearing,SKF bearing 22216E,22216CC/W33,22216 BEARING bearing size SKF spherical roller bearing 22216 dimension bearing inner diameter 80mm bearing outer diameter 140mm bearing width 33mm CXRB BEARING is 22216 china bearing manufacturer, factory,supplier and exporter, we focus on produce spherical roller bearing 22216,The design (cage)of spherical roller bearing :CAK/W33,E,E1,EAE4,CC/W33,EAS.M,C,MB/W33,BS 22216 bearing design and applincation 22216 Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions. 22216 bearings are widely used in Papermaking machinery, railway vehicle axle, rolling mill, roller gearbox, crusher,vibrating screen, printing machinery,woodworking machinery,industrial reducer,mine.and 22216 bearing are popular size that could be used in many applications. Also we deal in world famous brand bearing like SKF bearing 1.SKF bearing Group adopted ONLY High quality GCR-15 chrome steel . 2.SKF 22216 bearings are all produced according to ABEC-1,ABEC-3 strictly. 3.100% testing before shipment, 4,ISO 9001 certificate 5.highly skilled technical staff and advanced testing equipment Advantage of SKF 22216 spherical roller bearings 1.competitive price 2.many years experience cooperation with SKF,FAG,NSK,NTN,TIMKEN,KOYO,NACHI,SNR,ZKL,ZWZ,HRB etc. 3,Strong production capacity can make sure the delivery the goods as soon as possible 4.Reliable operation quality if you have demand for SKF spherical roller bearing 22216,please contact with brandbearings@gmail.com
