☆ product features
Tapered roller bearings, the outer ring with a tapered roller, between the raceway with roller cone. If the extension of the cone-shaped face, bearing on the ultimate convergence point on the axis. Tapered roller bearings for radial load to bear the main radial, axial load joint. Bearing the axial bearing capacity of the decision by the contact angle, the larger the antenna, the greater the axial bearing capacity. Tapered roller bearings for the separation-bearing, with roller cage and the inner components of the inner ring, outer ring and can be separated Installation.
The species may limit the shaft bearings or shell side of the axial displacement, does not allow the relative axial tilt a shell hole. In the radial load, there would be some additional axial force, supported by two bearings in general, the bearing inner and outer ring should end with the installation of the relative.
The main purpose of such bearings: automotive front, rear, transmission, differential, the pinion shaft, spindle machine tools, construction machinery, large-scale agricultural machinery, rail vehicles, gear deceleration device, a small rolling mill roll neck deceleration devices.

ZWZ metric production, the British single, double, 4 Tapered Roller Bearing Structure

Single row tapered roller bearings
Such restrictions can only be bearing axis of the shell in one direction or the axial displacement, under the direction of an axial load. Radial load in the role, bearing in axial force arising from the balance needs to be addressed. Bearing that the two face-to-face or use the back-to-back.

Two-Row Tapered Roller Bearing
Tapered Roller Bearing this in the radial load to bear at the same time affordable two-way axial load. Bearing in the axial clearance limit the scope of axle shell or two-way axial movement.

4 Tapered Roller Bearings
Bearing this performance with two-row tapered roller bearing is basically the same, but more than double row tapered roller bearings to bear a greater load of radial, slightly lower speed limit, mainly for heavy-duty machinery, such as rolling mill, and so on.

Closed more than two-and four-row tapered roller bearings
ZWZ to provide long-lived, sealed more than two-and four-row tapered roller bearings. Personalize bearing on the new design, to change the whole design of the traditional method of sealed bearings, sealed with a combination of dust-proof seal a new structure to improve the sealing effect of sealing to improve performance. Closed more than two-and four-row tapered roller bearings with open-bearing structure, life expectancy increased by 20% to 40%; lubricant to reduce consumption to 80%.

Multi-bearing seal with post-code signs XRS.
Mid-size range
ZWZ Tapered Roller Bearing the basic dimensions are listed in size datasheets,
Single row tapered roller bearings:
Diameter size range: 20mm ~ 1270mm
Outside diameter size range: 40mm ~ 1465mm
Size range width: 15mm ~ 240 mm
Double row tapered roller bearings:
Diameter size range: 38mm ~ 1560mm
Outside diameter size range: 70mm ~ 1800mm
Size range width: 50mm ~ 460 mm
4 Tapered Roller Bearings
Diameter size range: 130mm ~ 1600mm
Outside diameter size range: 200mm ~ 2000mm
Size range width: 150mm ~ 1150 mm
 
● Tolerance
ZWZ metric tapered roller bearings with a general tolerance level, but also to provide P6X, P6, P5, P4, P2 tolerance level, with all GB307.1.

British ZWZ tapered roller bearings with a general tolerance level, may also be required to provide CL2, CL3, CL0, CL00 tolerance level products.
 
◇ radial clearance
ZWZ single row tapered roller bearing is installed in only after clearance, and another in the opposite direction to position the bearings can only be determined after regulation.
◆ Cage
Tapered Roller Bearing the general use of steel stamping, basket-shaped cage, but a larger size, the car will also adopt the pillars of the system entities Cage.
1. When the bearings D ≤ 650mm diameter, using steel plate stamping Cage, Cage code did not post signs

2. Bearings when the outer diameter D> 650mm, the use of steel pillars of the entity Cage, Cage did not sign the code post
□ equivalent dynamic load
P = Fr KN] when Fa / Fr ≤ e time
P = 0.4Fr + YFa [KN] when Fa / Fr> e time
Single row tapered roller bearings used in pairs (the basic shape can be different sizes), bearing in the calculation of the equivalent dynamic load must be included in the radial load caused by the additional axial force. Single row tapered roller bearing axial force of the additional S, can be determined using the following equation similar to: S = Fr/2Y
 
■ equivalent static load
Single row tapered roller bearings
P0 = 0.5Fr + Y0Fa KN]
If the P0 4 and the double row tapered roller bearings
P = 0Fr + Y1Fa [KN] when Fa / Fr ≤ e time

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

Equivalent static load
P0 = Fr + Y0Fa [KN]
Fa and Fr refer to the role of the single, double row and bearings 4 on the total load.
