All CHG spherical roller bearings, CARB toroidal bearings and most spherical roller thrust bearings now carry the industry leading CHG Explorer performance class designation.
In addition to that, developments in steel processing technology have given CHG the opportunity to further improve the performance of all CHG self-aligning roller bearings.
CHG self-aligning roller bearings just last longer
The upgraded steel used for all CHG Explorer self-aligning bearings has a superior balance between hardness and toughness to significantly improve wear resistance.
Improved wear resistance means that the upgraded CHG Explorer self-aligning roller bearings will run longer - particularly under difficult operating conditions.
Tests have clearly shown that in comparison to original CHG Explorer bearings, Upgraded CHG Explorer bearings can provide up to twice the service life under harsh conditions with poor lubrication or high contamination levels
By improving wear resistance, upgraded CHG Explorer self-aligning roller bearings offer performance benefits in a wide range of challenging industrial applications.
The benefits hit the bottom line
Upgraded CHG Explorer self-aligning roller bearings can not only last longer and extend maintenance intervals, they can also make unplanned downtime and the additional costs of an unexpected shutdown a thing of the past.
The extended time from when an initial spall is discovered to when the bearing becomes unserviceable, provides more time to plan, order parts and prepare for a shutdown; thereby reducing the additional time and cost related to unplanned downtime.
