Introduction

Double row tapered roller bearings are two rows of tapered roller bearings, tapered roller bearings are designed to withstand both radial and axial forces of the composite load, mainly used in high stiffness, continuous operation of the occasion, in limited space and compact layout can provide stable performance.

Features and Benefits

●High load carrying capacity

Double row tapered roller bearings are suitable for heavy radial and axial loads.

●Axial loads in both directions

Double row tapered roller bearings locate the shaft in both directions with a specific axial clearance or preload.

●High stiffness

Double row tapered roller bearings provide a stiff bearing arrangement.

●Low friction

The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction.

●Long service life

The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles of XRL Explorer bearings optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles.

●Enhanced operational reliability

Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

●Consistency of roller profiles and sizes

This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately.

Structure and Features

Double-row tapered roller bearings have a variety of structures, the largest of which is type 35,000, with a double raceway outer ring and two inner rings, and a spacer between the two inner rings. The clearance can be adjusted by changing the thickness of the spacer. This type of bearing can bear both radial load and bidirectional axial load, and can limit axial displacement of the shaft and housing within the axial clearance range of the bearing.

Application

Double row tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills and machines in the mining industry, e.g. tunnelling machines.
