Hi

The industry calls them Sintered Bronze bushings ASTM standard: ASTM B433 Grade 1 Type 2.

I have used them for years. While they are not “ever lasting” they do last a lot longer than plain brass or bronze bushings. They are highly impregnated with lubricant. Recently when reaming some to fit an axel shaft the lubricant would drip off the reamer during the reaming process.

The bushing before insertion......................................... .............................................Reami ng process........................................... .......................................Finished

This unit when installed on the machine will not be located where it can be lubricated.The ones they replaced lasted about 30 years.
