China Factory Supply Taper Roller Bearing
* 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.
* Product Categories
ZGXSY 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
ZGXSY 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 ZGXSY 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
ZGXSY 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.
ZGXSY inch tapered roller bearings with Normal tolerances, according to need and available CL2, CL3, CL0, CL00 level tolerance products.
* radial clearance
ZGXSY 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
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
Double-row and four-row tapered roller bearings
Equivalent static load
Fr and Fa are by acting on the single row, double row and four row total load on the bearings.
