Design Classification :

1.Single Row Cylindrical Roller Bearing

Single row cylindraical Roller Bearing can be classified in NU,NJ,NUP,N,NF and so on .Inner ring outer ring are separeable.It can bear axial load from one direction.It's generally made of dteel stamping or brass cage and some of them are using cage of formed polyamide.

2.Double Row Cylindrical Roller Bearing

NNU-design double cylindrical roller bearing.They are separable,which means ring with complete flange,roller and cage can be installed with other rings,or all the bearing components can be installed separately,whjich is favorable for stalling,checking and maintaining.The bearings of NNU-design have a conical bore generally.These bearings are possoble to reach certain radial internal clearance or certain preload.

3.Four Row Cylindrical Roller Bearing

Four Row Cylindrical Roller BearingS are almost used for roller neck of mill housing,rollers and rolling machines.Compared with other roller bearing,these bearing are characterized by low friction.They are always interference fitted on roll necks especially application to rolling machineswhich rolling at a high speed.

CAGE CLASSIFICATION

1.EM double assembly machine process copper cage with outer ring or inner ring centered.

2.EM pressed steel cage with rollers centered.

3.EP-nylon cage with rollers centered.
