Detailed description

Application

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

Application of Cylindrical roller bearing:

Cylindrical roller bearing is widely used for motors ,autos.mill handing machinery and various kinds of industrial machinery,

Features:

Bearings of TB design

Semi-locating bearings

Axial displacement of inner ring

Sealing

Lubrication

Operating temperature

Suffixes

Single row full complement cylindrical roller bearings have solid outer and inner rings together with rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage.

Single row full complement cylindrical roller bearings are in the form of semi-locating bearings.

Sealing

The cylindrical roller bearings are supplied in an open design.

Lubrication They are not supplied greased and can be lubricated with oil or grease via the end faces.

Operating temperature

Full complement cylindrical roller bearings are suitable for operating temperatures from -30 °C to +120 °C.
