(R) Bearings, Plain, Self-Aligning, Self-Lubricating, High Speed Oscillation -65 to +160 Degrees F General Specification For
|Publication Date:||1 September 2010|
This standard covers the requirements for spherical, self-aligning, self-lubricating bearings which are for use in the ambient temperature range -65 to +160 °F (-54 to +71 °C) at high cyclic speeds. The scope of the standard is to provide a liner system qualification procedure for helicopter sliding bearings defined and controlled by source control drawings. Once a liner system is qualified the source-controlled bearings are further tested under application conditions.
The bearings are intended for use in critical helicopter applications where they are subjected to low loads and high frequency oscillation.
