Balance rail bearings

[Newton Hunt]

The strips are their to prevent the bering from twisting.

The pin hole in the bearings are drilled at an angle equal to the
angle of the balance rail pins.  The bearings are not reversible. 
That is why one side of the bearing is darkened, albeit not enough
often.

By standing the action on the back rail and protecting the stretcher
from the drop screws one can move the keys and bearings far enough to
see what is under the bearing and remove what is needed with a good
pair of forceps.

Steinway, or any manufacturer, is cheap and will not do anything they
do not have to do even if we do not always understand their
rationale.  DOn't mess with it unless you really understand it.
