Motor repairs
(OP)
For repairing worn out shaft at bearing seat and worn out bearing housing on end shields of motors 30-300kW, use hot metal spray OR put a sleeve. How does cost compare to performance.

RE: Motor repairs
Metal spraying / sleeving of shafts - Not a good idea.

RE: Motor repairs
Shafts seem a little trickier. There seem a wide variety of exotic processes that I am not particularly familiar with - we recently had one repaired using "flame spray" which I believe is a good process (it was recommended by a good shop).
edison - what kind of process do you recommend to build up an undersized shaft?

As for undersized shafts, my mantra - replace it. Always.
Shaft spraying... sleeving ... been there, done that, got scars to prove it.
BTW, the OP has to investigate the root cause for the shaft journals failing. The cure is expensive ... at least in my clinic.
