Product Description:

- Single row Tapered roller bearings

Single row roller bearings can only bear the shaft or shell of a direction of the axial

displacement and a direction of the axial load. So we need the two bearing face to face or

back to back to use.




★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:What are the general uses of tapered roller bearings?
At the time of greater radial load and axial load
Q:Taper roller bearing limit speed 20
First of all, different types of tapered roller bearings, the limit speed is different. Bearing on catalog.Second, the calculation of bearing limit speed is calculated by computer simulation of bearing manufacturer. It is very complicated. Mainly based on frictional heat generation and cage strength limit.So, we use bearing technology or design personnel, only need to control your speed in the following catalog bearing manufacturers can.In addition, oil lubrication is better than grease lubrication at the same speed.
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:Tapered roller bearing suffix code YA2 stands for what does that mean?
I often see that bring happiness to people's lives in music is painful, hard after the success of scientists occasionally see a mirror inside the grey haired, new Chinese often over the slightest grief, I often heard people said in an interview, while working hard, but I'm happy indeed! They bear varying kuzhongzuole, showing their amazing persistence and noble quality to enjoy life without, but it is not difficult to see their happiness included "self denial".
Q:How to judge the positive and negative sides of the tapered roller bearings,
The bearings do not have to distinguish between the front and back, and there is no positive and negative said, only in accordance with your actual use to identify the installation direction.
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
Q:Tapered roller bearing: Bearing expert why burned or locked
Shaft tolerance is relatively small and fine head, the inner shell inside and nose has obvious signs of friction. If there are traces of friction on one side or on both sides of the inner shell, there is an abnormal contact with the inner shell of the bearing and the friction of the inner shell of the bearing.2, the inner shell shell burning marks are not serious, roller black even deformation, generally is the inner shell or casing tolerance, Ambassador bearing gap smaller, and even negative tolerance caused by burning. Or in the maintenance of the bearing selection is not correct, you can use large clearance bearings.3, the shell burned seriously, the inner shell, roller are no obvious changes, you can observe whether the shell has traces of friction. There are traces of friction on the outside, and it can be considered that the tolerance between the bearing shell and the shaft is insufficient, which results in abnormal friction caused by the slipping of the housing. If there are traces of friction on one side or on both sides of the shell, there is an abnormal contact between the component relative to the bearing housing and the bearing housing, and the heat generated by friction will be burned out.
Q:Is the tapered roller bearing so correct?
Tapered roller bearings are designed for the inner ring, outer ring raceway and roller cone vertex on the central axis of the bearing, radial load acting on the bearing, axial force is generated. Therefore, it is necessary to use the 2 bearings for use, or as double pairs of bearings, double row bearings. Combination and double row tapered roller bearings, when radial loads act on tapered roller bearings
Q:Reasons for the damage of tapered roller bearings used on motors - -
To LZ: 1 it is recommended that the radial force and the rated load of the bearing be compared to determine whether the radial force is too large (if there is axial force, it needs to be synthesized as equivalent load, and then compare.) In 2 section, you basically is the middle of the two row tapered bearing ring and then as a double row tapered to use (not in general, so natural clearance installed back to back) without gasket or nut to adjust, this is a very good idea.
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). I hope they can help.Single row tapered roller bearings (taken from GB/T 297-1994)Bearing code |30000: 32914 X2Basic size /mm|d: 70Basic dimensions /mm| D: 100Basic size /mm|T: 20Basic size /mm|B: 19Basic size /mm|C: 16Installation size /mm|da (min):-Installation size /mm|db (max):-Installation dimension /mm| Da (min):-Installation size /mm|Da (max):-Installation size /mm|Db (min):-Installation size /mm|a1 (min): 4Installation size /mm|a2 (min): 6Installation size /mm|ra (max): 1Installation size /mm|rb (max): 1The other is /mm|a size: 19Other sizes /mm|r (min): 1Other sizes /mm|r1 (min): 1The calculated coefficient is |e: 0.33The calculated coefficient is |Y: 1.8The calculated coefficient is |Y0: 1Basic rated load /kN|Cr: 53.2Basic rated load /kN|C0r: 85.5The speed limit / (r/min) | fat: 3600The speed limit / (r/min) | oil: 4500The weight is /kg|W:-
