A reasonably simple machining job.
Although not mandated by the relatively low load, much tighter tolerances
and, consequently, lower noise, could be achieved by specifying a
super-precision bearing, say, an ABEC 7 or 9.
But, a "plain" bearing will likely be quieter than a "frictionless"
bearing.
An ABEC 7 or 9 ball bearing will outlast the Kinor 35H itself by at least
two centuries.
