CURRENT

AS85598

This standard defines general requirements for spherical, radial-journal, conical, and thrust bearings which are of laminated elastomeric construction. These bearings are for use in an environment having a temperature spectrum of -65 to +160 °F while reacting steady state loads in addition to oscillating loads and motions. The operating temperature range of -65 to +160 °F reflects the current temperature range for existing parts, but allows for expansion in the future.

ARP5448/7

This standard details two methods of inspecting TFE lined spherical or journal bearing wear outside the test apparatus. The methods described herein are applicable only to bearings which were unidirectionally loaded and the area of sliding wear is known and held constant throughout the dynamic test. The two methods described are: a Destructive Inspection - Cut and measure (not applicable to molded liners) b Non-destructive Inspection - Radial play (gage) measurement

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.
