White metal bearing composition

White metal bearing composition

White metal bearing composition

(OP)
Our customer wants to change tin based white metal to lead based white metal for his 100 MW Hydro generator bearings. What will be the repercussions ? Where can I find info on these bearing metal compositions ?

Thx in advance.

RE: White metal bearing composition

ASTM B23 gives details.
The lead based Babbitt Metals have lower strength than the tin base so the load carrying capacity is reduced.

Thx carburize. I downloaded the std b23 (though $28 for 3 pages seems a bit stiff). It was quite informative.
