nsk/timken tapered roller bearing 31311 in good quality for machines

Quick Detail:

Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.

Design Attributes : Single cone and cup. One-piece pressed steel cage retains rollers on the cone and spaces them evenly

Description:

the tapered roller bearing,the inner and outer races are tampered,with tampered rollers between races,The tapered roller bearing is mainly used to carry the radically and axially combined load,mainly the radical load.The inner components and the out ring of the bearing are detachable,facilitating assembly and disassembly.The axial loading capacity of bearing depends on the contact angleα,the larger which is,the larger the axial loading capacity will be.Such bearing is widely applied to automobile,gearbox,main shaft of machine tool,constructional mechanisms,rolling stock and rolling mill journal.

high-load, radial/thrust capacity and
direct/indirect mounting variables of
tapered roller bearings into assemblies
of maximum load rating in minimum space.
Cage Tapered roller beating generally use die stamping steel plate basket cage,also can use machined solid cage if its dimension is bigger.
Allowable angle error
Tapered roller beating generally is inadmissibility inclination between axis and case shell hole.If there is,cant be bigger than 2'
Clearance Only after arrangement single row tapered roller beating could appear clearance,and should be detemined after adjusted by another right-about localization bearing.The clearance of double row and four row tapered roller bearing can be provided with relevant standard according to the requirement of the customers
 

Applications:

Typical applications: Machine tool spindles Gear reduction units Automotive transaxles Transmissions
