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.
