Title:Plain Bearing Wear Measurement
Issuing Committee:Acbg Plain Bearing Committee
Scope: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【英文标准名称】:Rubber,vulcanizedorthermoplastic-Determinationofstressrelaxationincompressionatambientandatelevatedtemperatures(ISO3384:2005);EnglishversionofDINISO3384:2008-07
