product name: Extra Large Tapered Roller Bearings
Tapered Roller Bearings
The Tapered roller Bearings are able to support radial load and thrust load in one direction.The tapered roller bearings suffixed have a higher load carrying capacity.

TAPERED ROLLER BRARINGS
Tapered roller bearings are designed such that cup, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. This type of bearing is suitable for applications that involve radial load or axial load combined with radial load.Bearing load capacity depends on contact angle of α such that if a is larger, bearing load capacity goes up. It will a large contact angle if α>25°.
Tapered roller bearings are split type mounted with cup and cone assenbly(rollers and cage) separately.
Single-row tapered roller bearings
This type of bearing is able to carry radial and axial load in one directions simultaneously be cause an axial component of force is produced then this type of bearing is loaded radially, two bearings are used together facing one another,or two or more bearings are matched and used(Fig.1)
Double-row tapered roller bearings
This type of bearing can carry radial load and axial load in both directions simultaneously.these bearings can limit the axial displacement of shaft or housing in both directions within bearing axial clearance.(Fig.2,Fig.3)
Cage
Tapered roller bearings normally use stamped steek cage with pockets
Allowable angle deviation
For tapered roller bearings. Misalignment of shaft against housing bore is not allowed. If existing,misalignment should not exceed2'.
Clearance
Single-row tapered roller bearings has a clearance only after being mounted and adjusted by the other bearing positioned in contrary direction.the clearance of double-row or four-row tapered roll bearings could be given as per customers' requests or relative standards
Dynamic equivalent load
Single-row tapered roller bearings
When two single-row tapered roller bearings are used together facing one another,an axial component of force is produced under radial load.in this case,refer to following equation for calculation of this axial component force
Double-row tapered roller bearings
Static equivalent load
Single-row tapered roller bearings
Double-row tapered roller bearings
Fr and Fa are total load applied on single-row,double-row and four-row tapered roller bearings.
Calculation factors of e.Y,Y1,Y2 and Y0 are listed in bearing specification tables.
Main applications
These bearings are often used on front and rear wheels,transmissions,gear shafts, machine tool spindles ,construction equipment.heavy agricultural machinery,rolling stock speed reduction gear,rolling mill roll neck etc.
