Our Test & Development Lab

Kaman Specialty Bearings Test & Development Lab

Kaman’s full service test & development lab is equipped with test fixtures designed and built by our dedicated test and applications engineering team.


While the majority of testing is aerospace related, the test facility is outfitted with modular testing stands that can support a great variety of testing configurations, including driveshaft high and low cycle fatigue testing, or cam follower and track roller endurance, friction, and environmental testing.
