Explanation for Cylindrical Roller Bearing

CYLINDRICAL ROLLER BEARINGS
Linear contact exists between the roller of the cylindrical roller bearing and
the tray with big radical load capacity.So it is suitable for high speed rota-
ting from the view of it structure. This kind of bearings include all types of
bearing, rollers guided by the inner or outer rings.

We can provide thousands of specifications of products, cylindrical bearings, cylindrical rollers, clutch release bearings and also can design and manufacture the special or non-standard dimensions or specs of needle roller bearings according to the customer's requirement, drawing, sample.

Structure

NU	Shifting bearings
NJ	Singledirectionalpositioned bearings
NUP	Positioned bearing
N	Shifting bearings
NF	Singledirectionalpositioned bearings

The cylindrical roller bearings of various structures are divided as per the different retaining edges.NU type cylindrical roller

bearings have two retaining edges on the outer ring with non-retained inner ring. N type cylindrical roller bearings have two

retained inner rings with non-retained outer ring. Both NU and N types cylindrical roller bearings are shifting bearings with

separable inner and outer rings for easy dismounting.NJ type bearings have double retained outer rings with single retained

inner ring.NF type bearings have double retained inner rings with single retained outer rings.They can bear the single direc-

tional axle force.NUP type cylindrical roller bearing is used as fixed bearing which can bear the alternative directional axial

force. Bearings of this type have double retained outer ring with one retaining ring.

Re-enforced cylindrical roller bearing

To distinguish from the common cylindrical roller bearings, the re-enforce
E cylindrical roller bearings are marked with the suffix E.This E type bea-
ringshave the same main dimensions as the common bearings except
the increased diameter,length,and numbered of the rollers.The load capa-
city is also enhanced accordingly.This type bearings have big rational load.
So as shown in Figure, when compared with the common bearings of the
same shaft diameter, the bearing outer diameter should be reduced or the
shaft diameter should be increased when the bearings with same outer d-
iameter are used so that the rigidity of the shaft can be enhanced.Besides,
the incircle of E type is different from the common bearings , so they are
not inter-changeable.

Retainer

Steel plate punched retainer or entity retainer are used with cylindrical roller bearings are common used for cylindrical roller

bearings . But retainers made of fiber glass re-enforced nylon 66 is also used for the temperature of - 20-200C, or for 1500C

short time operation.

Mounting

The bearing groove will only stick to the shaft shoulder or the outer casing shoulder.It can not be clipped by the shaft or the

chamfered angle of the outer casing.Therefore,the maximum radius of the combinative parts must be smaller than the mini-

mum value of the chamfered angle of the cylindrical roller bearings. The separable inner ring must be clipped tightly in axial

direction if there exit the axial direction force in operation. Meanwhile , for the tightly combined bearings bush ring, no mou-

nting or dismounting forces are allowed to be transferred directly through rollers or retaining edges during mounting or dism-

ounting.
