ISO 3228:2013 PDF

Scope: This International Standard specifies boundary dimensions and tolerances for cast and pressed housings for insert bearings for which boundary dimensions are given in ISO 9628[1]. It applies to plummer block housings, flanged housings and take-up housings. The inclusion of relubrication features is optional, but when provided it is intended that they intersect the zone specified in ISO 9628[1] in such a way that lubricant satisfactorily feeds from the housing through this zone. The exact design of the relubrication features is not otherwise covered by this International Standard.
