Product Description:

- Double row tapered roller bearings

Double row tapered roller bearings can only bear radial load at the same time it can be

subject to bi-directional load. It can be in bearing axial clearance range limit shaft or shell

two-way axial movement.




★Product features

The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the

raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing. The rollers are guided by a

flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum. The larger the half angles of these

cones the larger the axial force that the bearing can sustain.


★Product application

In many applications tapered roller bearings are used in back-to-back pairs so that axial

forces can be supported equally in either direction.

Pairs of tapered roller bearings are used in:

- car and vehicle wheel

- mining equipment

- moderate speed

- engine motors

- axle systems

- construction

- agriculture

- reducers

- gear box


★Horton tapered roller bearings Basic size

- Single row tapered roller bearings:

Inner ring size: 20mm ~ 1270mm Outer ring size: 40mm ~ 1460mm Width size: 15mm ~ 240mm

- Double row tapered roller bearings:

Inner ring size: 38mm ~ 1560mm Outer ring size: 70mm ~ 1800mm Width size: 50mm ~ 460mm

- Four row tapered roller bearings:

Inner ring size: 130mm ~ 1600mm Outer ring size: 200mm ~ 2000mm Width size: 510mm ~ 1150mm


★Tolerance:

Horton tapered roller bearing with common

tolerance, and also provides P6X, P6, P5, P4,


★Radial clearance

Horton single row tapered roller bearings only

in after installation have clearance, and in


★Cage

Tapered roller bearing general ues the steel plate stamping, basket shape cage, but when the size is bigger, we

also adopts entity cage.

1. Outside diameter D ≤ 650mm, use the steel plate stamping cage, cage postposition without code mark.

2. Outside diameter D > 650 mm, use the steel entity prop cage, cage postposition without code mark.


★Dynamic equivalent load

P = Fr [KN],     Fa / Fr ≤ e;

P = 0.4Fr + YFa [KN],    Fa / Fr > e.

The single row tapered roller bearings used in pairs (basic physical size can be different), when calculation  the

equivalent dynamic load of the bearing, must be included in the radial load cause additional axial force. The single

row tapered roller bearing additional axial force S, can approximate formula: S = Fr / 2y


★Static equivalent load

Single row tapered roller bearings 

P0 = 0.5Fr + Y0Fa [KN] P0 < Fr, then P0 = Fr

Double row tapered roller bearings 

P = 0Fr + Y1Fa [KN],Fa/Fre ≤e P = 0.67Fr + Y2Fa [KN],  Fa/Fre > e

Q:Tapered roller bearings. Are the rollers tapered?
The frustum of the cone can be seen as a right angled trapezoid revolving around the right angle, and the top is a circle. Can also be seen on top of the tip is tapered off, the tapered roller head is not a round face
Q:Dimension parameter of thrust tapered roller bearing.
Which size do you want, eldest brother? How do I make so much?GB/T: recommended national standards; GB: mandatory national standards4663: taper roller national standard codeThere is a missing release year later!It should be: GB/T 4663-1994
Q:What are the E and Y values of the 30209 bearings of tapered roller bearings?
The shoulder of the positioning shaft is positioned; the transition shaft shoulder is provided for the disassembly of the parts on the shaft or the prevention of the stress concentration. But the axial shoulder will inevitably increase the diameter of the shaft, and the shoulder of the axle will change due to the stress concentration.
Q:The installation of tapered roller bearings
2, when installed, the direction of the roller tilt there is a regulation? Must be the same as the following picture?:You say that the direction of the tilt is actually the same direction of the bearings, the installation of the problem to different ah!
Q:Small problems of roller bearings of tapered roller bearings
Cylindrical rollers are used only when the raceway is a cylinder.Mechanical drawing clearly stipulates the simplified drawing method of tapered roller bearings. Rollers are drawn into cylinders.
Q:Can tapered roller bearings be installed in a vertical direction?
Whether horizontal mounting or vertical installation, the axial direction is axial and radial is radial
Q:Internal and external tolerances for tapered roller bearings?
Less points, huh, huh?Bearings are tested with a dedicated bearing inspection instrumentTable seat:Outside diameter D913Internal diameter D923Height G904With standard and special micrometer (usually microkators and leverage comparator)Each inspection procedure has the corresponding inspection instructionYou can provide the job instructions free of charge to your bearings suppliers as a project to review their process controlAs for the instrument, you should pay for it even if your supplier offers itIf you buy the bearings in the retailers, then you have to pay for them yourselfThe work instructions may also have to be replaced by money
Q:Tapered roller bearings, 70 in diameter, please tell me the model number
What about outside diameter (D) and width (B)? You didn't say?.Following are all series of codes and sizes for tapered roller bearings (single column and double row).

Q:How does the roller of tapered roller bearings fit in?
Tapered roller bearings in the production of equipment, it is the first roller and cage assembly, and then into the inner ring, composed of components. Tapered roller bearings as long as the assembly, even if completed the inner ring, because the outer ring is only one ring.I don't know if you'll understand.
Q:Tapered roller bearings 32010x, two matching, how to install?
Suitable for heavy load and impact load. In addition to single row bearings, tapered roller bearings include double row bearings, pairs of double bearings and four row bearings. The taper roller bearing holder usually adopts a punch holder.
