TOUGHMET SUNRISE CASE STUDY


 Toughmet bearing comparisonHeavy Equipment Bushings

COMPANY PROFILE

Sunrise Aggregates, Danville, Michigan-- produces about 1 million yards of gravel and sand a year for Michigan Department of Transportation highway projects. The company risks significant fines if it does not deliver gravel and sand on time. During peak season, Sunrise Aggregates runs its excavators at high speeds 100 hours a week, digging through clay and gravel – often underwater.

APPLICATION

Caterpillar 350L excavators 

CHALLENGE

OEM pins and bucket bushings wear out at approximately 3,500 hours, much faster than other joints which last about 8,000 hours. Manual lubrication is required every three hours when digging in water.

SOLUTION

Sunrise replaced steel bushings with ToughMet on two CAT 350L excavators. The ToughMet bushings were checked at 8,100 hours. There was little wear and no change in performance, even with some skipped lubrication cycles. The ToughMet bushings were put back in service on the excavators.
