PRODUCT OVERVIEW

Understanding the
Double Row Taper Roller Bearing

Double row taper roller bearings are heavy-duty rolling-element bearings designed to support high radial loads together with axial loads in both directions. Two rows of tapered rollers share the load, giving high load capacity and rigid shaft support in demanding applications.

BEARING CONSTRUCTION: Two rows of tapered rollers run between conical raceways on the inner and outer rings, with the rows angled in opposite directions. This arrangement carries combined radial and axial loads in both directions while keeping the shaft positioned accurately and rigidly.

About

Double-Row Taper Roller Bearings

Two rows of tapered rollers work together to carry heavy radial and axial loads in both directions.

IR

Inner Rings (Cones)

The cones fit on the rotating shaft and provide the tapered inner raceways for both roller rows.

ROTATING COMPONENT
OR

Outer Ring (Cup)

The double cup sits in the housing and provides the tapered outer raceway for both roller rows.

SUPPORT COMPONENT
TR

Tapered Rollers

Two rows of precision tapered rollers make line contact between the races to carry combined loads.

ROLLING ELEMENT
C/S

Cage & Spacer

Cages guide the rollers in each row, and the spacer sets the internal clearance between the two rows.

FAQ

Double Row Taper Roller Bearing Guide

Understand the essential information before selecting a bearing for your application.

01 What is a double row taper roller bearing? +
A heavy-duty rolling-element bearing with two rows of tapered rollers running between conical raceways on the inner and outer rings. It supports high radial loads together with axial (thrust) loads in both directions.
02 Where are double row taper roller bearings commonly used? +
They are widely used in automotive wheel hubs and axles, industrial gearboxes, rolling mills, mining and construction equipment, and other heavy machinery.
03 How do double row taper roller bearings carry combined loads? +
The tapered rollers and conical raceways are set at an angle, so the load passes through the rollers in both radial and axial directions. With two rows angled opposite to each other, the bearing handles axial loads from both sides.
04 What is the difference between a double row and a single row taper roller bearing? +
A single row taper roller bearing carries axial load in one direction only and is usually mounted in pairs. A double row bearing carries axial load in both directions and offers higher load capacity and rigidity in a single compact unit.
05 How do I select a double row taper roller bearing? +
Bearing selection typically depends on factors such as bearing size, load, speed, shaft and housing dimensions, operating environment, lubrication and the requirements of the specific machine.
06 What information should I provide when requesting a bearing? +
Providing the bearing number, dimensions, application, machine type, operating speed and load requirements can help identify a suitable bearing specification.
