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:How to judge the positive and negative sides of the tapered roller bearings,
The installation of tapered roller bearings is not only to pay attention to the direction of installation, there are many other places to pay attention to, is a very professional technical activities
Q:Internal and external tolerances for tapered roller bearings?
Are you a bearing manufacturer or?The accuracy levels of the bearings are different, and the relevant tolerance levels are different. If it is not for your manufacturer, you can contact the supplier directly to check the data you want to check.If you are a manufacturer, you should have your internal size, accuracy, grade, and some, you can find the tolerance directly.
Q:Can tapered roller bearings be installed in a vertical direction?
Absolutely. The bearing below the figure is the tapered roller bearing placed vertically.
Q:Reasons for the damage of tapered roller bearings used on motors - -
This approach is somewhat similar to a tolerance control method invented by Timken (Timken) in 80s, and is suitable for mass production. But in this way, you have to control all the variables, or you'll probably have a problem with your bearings.
Q:Tapered roller bearings. Are the rollers tapered?
As the name suggests, the roller of tapered roller bearings is conical, rather than a frustum of a cone. The roller of cylindrical roller bearings is cylindrical.
Q:Why is the cage of tapered roller bearings loose?
It is loose, the outer frame of the bearing cone is removable, as long as it is easy to install and add lubricant. You can come up with the relevant standards, must belong to the bearing standard parts, as long as you meet the standard requirements of the bearing can be spread!
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:Method or tool for measuring clearance of tapered roller bearings.
You can measure the oil gap with a drop bar, that is, a soft drop ruler, which can be purchased without measuring the instrument of the bearing
Q:There is a slot in the inner ring of tapered roller bearings, right? Is the roller in the slot?
There is a slot in the cone... The ball is placed in the slot
Q:What is the size of tapered roller bearings 352214?
Bearing type: tapered roller bearingNew model: 352214Old model: 97514EInternal diameter (mm):70Outside diameter (mm):125Width (mm):75
