6 Physical Characteristics:
1) Cylindrical roller bearing can be separated by single row,double rows and four rows.
2) This kind of bearing can be submitted to high radial load and some axial load.
3) The rolling element of cylindrical roller bearing is cylinder,the two ends of the external lines have the corrective slope which can eliminate the contact stress.
4) NN and NNU design cylindrical roller bearing have high rigid and apply to machines such as millings.
7 Moreover, we can manufacture these bearings according to customer's drawings and samples
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.
FC:Double outer rings,single inner ring,without ribs.
FCD:Double outer rings,double inner rings,without ribs.
FCDP:Double outer rings,with center and loose ribs,double inner rings,without ribs.
Packing of Cylindrical roller bearing:
1,Surface is covered with antirust oil.
2,Packed with water-proof plastic and professional tape rolling
3,It is put in plywood case to avoid the rust dust and moisture.
