CCCCCC19. Installation conditionsStuffing mandrel:The bushings must be stuffed into the bearing seat by means of a press inaccordance with the mandrel tolerances (recommended ISO-tolerance g8),in order to guarantee a perfect fit of the bushings as well as the definitivetolerances.PrefaceContentsOversized bushing before installation:The bushings are supplied with an oversizedoutside diameter in order toguarantee a secure attachment throughthe press-fit.The permissible oversizes are dependenton the outside diameter and are shown inthe marginal table.outside diameter¢d 2v(mm)oversizemin(mm)oversizemax(mm)6 - 10 0,05 0,0812 - 20 0,08 0,1222 - 50 0,10 0,1555 - 100 0,15 0,20MaterialoverviewDesignguidelinesBearing seat made from metal:105 - 150 0,20 0,28160 - 230 0,25 0,35The bushing hole is designed for a bearing seat of a bore tolerance H5.Other bore tolerances are possible.
