Tapered roller bearing is designed in such a way that cone apexes of inner ring raceway ,outer ring raceway and roller raceway intersects at one point of its central line ,beside metric series products.there are inch series products which are applicable for load and impact load for more details please contact with SKYPE:lianlian88661 !
1.single row tapered roller bearing
1.single row tapered roller bearing
Itcan bear simultaneously radial load and single row axial load
When carrying the radial load ,it creates axial thrust load ,thus two bearings can configured (or combined ) fact to face or back to back .according to contact angel difference ,it is classified into three types :small cone angle,medium cone angle and big cone angle .
2. double row tapered roller bearing
It is classified into two types :CAPPED AND OPEN
The former equips two race way outerring and two single raceway inner rings,the latter equips two race way outer rings and one double raceway inner ring ..both of them can bear radial load and double row axial load
In order to make bearing having required internal clearance after being installed ,it is inner /outer spacer are thinned previously
Four row tapered roller bearing
Four row tapered roller bearing is compossed of two double row inner rings and one double row outer ring consistingtwo single outer rings,between two inner rings ,there is one inner spacer among these three outer rings two central spacer is furnished ,whichcan be used to adjust clearance.when borne bear heavy radial load,it can bear simultaneously axial load in two different directions.but it is allowed speed is not much,which is mainly used for roller bearings of rolling mill.,in recent years,four row tapered roller bearing with double face sealis manufactured and gradually used in different industries..
Small sized bearing of this kind is generally made by bearing steel,for large sized one ,it is made by carburizing steelfor extremely large sized one ,it is made consisting hollow roller and supportcage to elongate its service life
Tolerance and clearance
Its tolerance is Po generallybearing with much more high level tolerance can be tailored according to clients requirements ,during assembly,it is clearance shall be adjusted according to adjustment specification and bearing manufacturing agreement (or standard clearance if there is no manufacturing agreement) after operating a certain period,client can readjust clearance please consult withOUR TECHNOLOGY DEPARTMENT FOR CLEARANCE ADJUSTMENT METHOD.
