Source of Duo-Art Rotary Pump Bearings
By Pat DeWitt
Hi, The bearings in the Duo-Art pump are a standard size and are
available from supply houses that sell these kinds of industrial
parts. Google on "bearings"; I found a supply house in my home town.
Note: the "Made in USA" bearings are not cheap. By searching on-line
I found that I could buy 10 foreign made bearings for less than a pair
of the USA-made ones.
So my rebuilt Duo-Art pump is running on a pair of foreign bearings and
I had eight more which I gave to a fellow friend rebuilder. The bottom
line is that new bearings are available and my pump runs very nicely.
Note: I am assuming that you are talking about the main crankshaft
bearings, not any of the ones on the individual bellows connector arms.
