* Product Features

Tapered roller bearings inside, the outer ring has a tapered raceways, raceway fitted between the tapered roller. If tapered surface extending eventually converge to a point on the bearing axis. Tapered roller bearings are mainly used to bear radial load mainly radial, axial joint load. Axial bearing capacity by the contact angle, the greater the reach, the greater the axial load capacity Tapered roller bearings for the separation of bearings, with roller and cage inner ring inner components can be installed separately from the outer ring This kind of bearing shell limit the axis or axial displacement side allowed tilt axis relative to shell hole. In the radial load, it will produce additional axial force, therefore, generally in two support bearings, the bearing outer ring and inner ring with the face should be relatively installation.

The main purpose of such bearings: automotive front, rear, transmission, differential, pinion shaft, spindle, construction machinery, large-scale agricultural machinery, railway vehicles, gear reduction, the rolling mill roll neck small deceleration devices.

CLUNT production metric, inch single, double, four-row tapered roller bearings - Types

Single row tapered roller bearings

Such bearings can only limit shaft or housing in one direction of the axial displacement in one direction to bear the axial load. In the radial load of action, the axial force generated in the bearing must also be balanced. Two face to face or back to back bearing should be used.

Double row tapered roller bearings

Such tapered bearings in radial load at the same time can withstand axial load. The axial clearance in the bearing within the shaft or housing to limit axial movement of the two-way.

Four-row tapered roller bearings

Performance of such bearings and double row tapered roller bearing is basically the same, but more than double row tapered roller bearings under radial load bigger, lower speed limits, mainly for heavy machinery, such as rolling machines.

Multi-sealed double, four-row tapered roller bearings

CLUNT provide long-life, multi-sealed double, four-row tapered roller bearings. Personalize bearing the new design, fully sealed bearing change traditional design method, using the new structure type seal and dust seal combination, to improve the sealing effect, improve sealing performance. Multi-sealed double, four-row tapered roller bearings compared with open structure bearing, life expectancy increased by 20% to 40%; lubricant consumption reduced by 80%.

Multi-sealed bearings with post-code XRS flag.

*  Size range

Tapered Roller Bearings CLUNT basic dimensions are listed in the data table size,

Single row tapered roller bearings:

Inner diameter range: 20mm ~ 1270mm

Diameter size range: 40mm ~ 1465mm

Width range: 15mm ~ 240 mm

Double row tapered roller bearings:

Inner diameter range: 38mm ~ 1560mm

Diameter size range: 70mm ~ 1800mm

Width range: 50mm ~ 460 mm

Four tapered roller bearings:

Inner diameter range: 130mm ~ 1600mm

Diameter size range: 200mm ~ 2000mm

Width range: 150mm ~ 1150 mm

*  Tolerance

CLUNT metric tapered roller bearings with a general tolerance level, but also provides P6X, P6, P5, P4, P2 tolerance class products, all consistent with GB307.1.

CLUNT inch tapered roller bearings with Normal tolerances, according to need and available CL2, CL3, CL0, CL00 level tolerance products.

*  radial clearance

CLUNT single row tapered roller bearings are mounted only after clearance and another in the opposite direction to adjust the positioning of the bearing can only be determined after.

*  cage

Tapered roller bearings generally use pressed steel, box-type cage, but the size is larger, also uses machined solid pillar cage.

1. When the bearing outer diameter D≤650mm, the use of steel stamping cage, the cage not sign post code

2. When the bearing outer diameter D> 650mm, use of steel pillars entities cage after cage code does not post signs

*  Allow angle error

*  equivalent dynamic load

P = Fr KN] when Fa / Fr≤e time

P = 0.4Fr + YFa [KN] when Fa / Fr> e when

Single row tapered roller bearings used in pairs (basic dimensions can be different), in calculating the equivalent dynamic bearing load, must be included in the additional axial force radial loads. Single row tapered roller bearing additional axial force S, it can be approximated by the following formula: S = Fr / 2Y

*  equivalent static load

Single row tapered roller bearings

P0 = 0.5Fr + Y0Fa KN]

If P0 <Fr then take P0 = Fr

Double-row and four-row tapered roller bearings

P = 0Fr + Y1Fa [KN] When Fa / Fr≤e

P = 0.67Fr + Y2Fa [KN] when Fa / Fr> e when

Equivalent static load

P0 = Fr + Y0Fa [KN]

Fr and Fa are by acting on the single row, double row and four row total load on the bearings.

Taper roller bearing are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.

Taper roller bearing are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings.

Taper roller bearing are designed to carry both thrust and radial loads and consist of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer.

Tapere roller bearing mainly carry radial, axial combined load with radial load in the main. The capacity of axial load carrying depends on the contact angle of outer ring’s raceway. The bigger the contact angle is, the greater the capacity will be.

Taper roller bearing the angle between the outer raceway generatrix and line, the bearing can bearing heavy load and other Tappered Roller Bearings, it mainly bears joint load based on one way axial load,but not only radial load.
