Product Details
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 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 ISO 3228:2013.
