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:Can tapered roller bearings be joined together with two single row tapered roller bearings instead of double row?The altar,
3, load and life usually do not vary greatly, this is a personal opinion. I hope I can help you!
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: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:-
Q:Internal and external tolerances for tapered roller bearings?
There is one thing that measures the inner diameterPlug coneThe outside diameter of the tool has not been seenThe tool set up is the watch standYou check it outIs it too troublesome to check each one?
Q:What is the 30207 judgment coefficient e of tapered roller bearings?
Dynamic load C: 51.2 kNStatic load Co:56 kNWeight about kg:0.32KGIf you accept my answer, please accept it in good time,~ if you accept my answer, please click on the "please answer" button~ ~ mobile phone question friends in the upper right corner of the client evaluation point [satisfaction].
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: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
3, bearing ring roller contact surface is cone surface or cylindrical surface?Cone surface, in order to be able to bear both axial force and radial force
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
