Taper roller bearings can be separated by inner circle, with roller, maintains the components and outer together can be installed. Roller and groove in the fixed contact line contact can reduce stress concentration. Taper roller bearings can withstand the big radial and axial load. Due to the taper roller bearings can transfer one-way axial load, therefore, to transfer in the opposite direction of axial load will need to another with symmetrical installation tapered roller bearings.

 1 . Taper roller bearings is the largest amount of single row circular cone roller bearings. In front of the car wheel in recent years, also use a small size double row circular cone roller bearings. Four row circular cone roller bearings by in large cold rolling machine, and heavy.

2 . Single row circular cone roller bearings, which formed a circle and a group of tapered roller shape by basket on comprehensive into a circle of inner component. Outer and inner circle components can be separated according to ISO tapered roller bearings, size, shape standard of any standard models of tapered roller bearing outer ring components can be inside or outside or inside the circle and the product realization international exchange component. The inner product namely except external dimension and tolerance must conform to ISO492 (GB307 and inner circle) specified taper Angle, component components must conform to the cone diameter and the relevant provisions of the swap.

 3 . Double row circular cone roller bearing outer ring (or in) is a whole. Two inner circle (or similar) and small end formed between every lap, clearance is on every lap to adjust the thickness of every lap, can also be used to adjust the thickness of the double row circular cone roller bearings are made.

 4 . Taper roller bearings are usually separated type, namely the belt roller and maintains a component within the circle of inner cone circles with conical outer (components can separate inner).

5 . Taper roller bearings are widely used in automobiles, rolling mill, mining, metallurgical, plastic machinery, etc.

Taper Roller Bearings belong to separated bearing, constituted by inner ring, outer ring, rollers and cage;Withstand huge radial load and axial load, pass one-way axial load only;The single row tapered roller bearings are used commonly;The single row taper roller bearings are divided into single row taper roller bearing, double row taper roller bearing and four-row taper roller bearing;The taper roller bearing is used in automobile, rolling mill, mining, metallurgical industry,plastic machinery , etc.

1.Characteristic :
Taper roller bearings consists of two main units, a cup and a cone. The cup is on the outer race whereas the cone consists of inner race, the separator and compliment of taper rollers. The tapered rollers are guided by the high load on the inner race. The tapered roller bearings are manufactured with interchangeable cups and cone on the shaft separately.
These bearings are capable of carrying both the radial and axial loads and permit fine adjustment for end play. Greater care is required to ensure the proper alignment of bearings and maintenance of proper axial clearance is essential to avoid bearing failure. Due to more development in the design of the tapered roller bearings, these are also available with 2 rows and 4 rows.

These bearings can limit the axial displacement of either shaft or the housing in one direction. When only radial load, the auxiliary axial force can be formed. It is suggested that two of the bearings be prt in face to face or back to back arrangements in application and the cup and cones should be mounted relatively to their end surfaces.

Tapered roller bearings are mainly used on variable speed devices, differential mechanisms, pinion shafts, machine tool sindles, construction machines, large size agricultural machines, gear deceleration devices for railway vehicles, and the small deceleration devices for mill roll necks.

2.Types :

  tapered roller bearings can be classified into following types :

  Single-row tapered roller bearing

  Double-row tapered roller bearing

  Four-row tapered roller bearing

  Multi-sealed double-row or four-row tapered roller bearing

3.Dimesion Range :

The basic dimensions of CLUNT tapered roller bearing are listed as followed :

(a)   Sigle-row tapered roller bearing

Bore diameter dimension range : 100mm-1270mm

Outside diameter dimesion range : 180mm-1465mm

Width dimension range : 63mm-240mm

(b)   Double-row tapered roller bearing

Bore diameter dimension range : 100mm-1560mm

Outside diameter dimesion range : 150mm-1800mm                      

Width dimension range : 66mm-460mm

(c)    Four-row tapered roller bearing

Width dimension range : 150mm-1150mm

Size range
Tapered roller bearings, the basic size has been listed in size data table,
Single row tapered roller bearing:
Inside diameter size range: 20 mm ~ 1270 mm
Outside diameter size range: 40 mm to 1465 mm
The width size range: 15 mm ~ 240 mm
Double row circular cone roller bearings:
Inside diameter size range: 38 mm ~ 1560 mm
Outside diameter size range: 70 mm ~ 1800 mm
The width size range: 50 mm ~ 460 mm
Four row circular cone roller bearings:
Inside diameter size range: 130 mm ~ 1600 mm
Outside diameter size range: 200 mm ~ 2000 mm

The tolerance
CLUNT metric tapered roller bearings are common tolerance, also provide P6X, P6, P5, P4, P2 level of tolerance, all consistent with GB307.1.
CLUNT imperial tapered roller bearings are common tolerance, according to the need can also provide CL2, CL3, CL0, CL00 tolerance products.
Radial clearance
CLUNT single row tapered roller bearing clearance only after installation, and have another in the opposite direction to determine after adjusted by the positioning of the bearing. cage
Tapered roller bearings generally USES the steel plate stamping, basket cage, but the size is bigger, also adopts pillar cage car system entities.
1. When the bearing outside diameter D is 650 mm or less, use stamping steel cage, cage post code are not sign
D > 2. When the bearing diameter is 650 mm, using a steel pillar entities cage, cage post code does not sign
Allow the Angle error
Equivalent dynamic load
P = Fr KN] when the Fa/Fr e or less
P = 0.4 Fr + YFa (KN) when the Fa/Fr > e
Single row tapered roller bearing used in pairs (basic shape size can be different), when calculating the equivalent dynamic load of bearings, must be included in the additional axial force caused by the radial load. The additional axial force S single row tapered roller bearing, it can approximate press type calculation: S = Fr / 2 y

Equivalent static load
Single row tapered roller bearing
P0 = 0.5 Fr + Y0Fa KN]
If P0 < Fr is P0 = Fr
Double row and four row circular cone roller bearings
P = 0 Fr + Y1Fa (KN) when the Fa/Fr e or less
P = 0.67 Fr + Y2Fa (KN) when the Fa/Fr > e
The suffix is defined

A: internal structure change
B: increase the contact Angle
X: the dimension adopt international standards
CD: double outer ring, with oil hole or groove.
