Bear up

摘要

Locating and sourcing a supplier of an obsolete mechanical component such as a bearing is a growing concern for many organisations, particularly if the component is part of a safety-critical system on an aircraft or nuclear power plant application. Sourcing a bearing for a mechanical system on a military aircraft, for example, can be a challenging process, particularly if the system is an ageing one. The aircraft itself may have been in operational service for more than 40 years and may also be projected to remain in service for many more years to come.
