- 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

★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
