replaceable bearings..as does the old Rotron CX-33, used on many FM

Goodrich used to sell rebuilt CX-33s but they were $700 each. I
modified several by drilling out the housings where a punch could be
used to tap out the old bearings. This helped in 24/7 service but I
suspect a 33 would outlast most of us in Amateur service.
