Description

This dataset has been created by the ISED (Industrial Systems Engineering and Design) research group at Politecnico di Torino to extend the available data for the development of fault detection models and predictive maintenance strategies for medium/large-sized spherical roller bearings commonly used in industrial applications, by resorting to a test rig with spherical roller bearings simultaneously monitored..

Building upon the previously released dataset focused on single localized defects, this new dataset introduces multiple defect conditions, including:

Bearings with two defects on the inner race.

Bearings with simultaneously defected in the test rig.

These additions allow for a more comprehensive evaluation of diagnostic models under more complex and realistic fault scenarios.

Experimental Setup

The data were collected using SKF 22240 CCK/W33 spherical roller bearings on the medium/large-scale bearing test rig developed by the ISED research group at Politecnico di Torino. The test rig is capable of independently applying both axial and radial loads to the bearings and can test bearings with an outer diameter of up to 420 mm. Tests are conducted at 10 nominal spin speeds and 4 load conditions (including one with axial load).

Dataset Structure

The dataset is organized into three main folders, each corresponding to a different fault configuration:

InnerRaceDualDamage – The fourth bearing (sensor 4) has two defects on the inner race, positioned 180° apart:

One defect: 2 mm diameter, 0.5 mm depth.

Second defect: 1 mm diameter, 0.5 mm depth.

OuterRaceDamage + InnerRaceDualDamage – The test rig contains:

A bearing at sensor 3 with an outer race defect (2 mm diameter, 0.5 mm depth), positioned at 0° with respect to the radial load.

A bearing at sensor 4 with the same dual inner race damage as in the first condition.

OuterRaceDamage + RollerDamage – The test rig contains:

A bearing at sensor 3 with an outer race defect
