Alexis,

how do you mount bearings in a "V" configuration?
Do you use a special fixture?

Thanks,
Alex

An alternative to a single bearing with a grooved OD for riding on a round
shaft is two regular bearings mounted in an 30-45 degree "V"
configuration. Adjust the spacing at the bottom of the vee to accomodate
the dia. of your shafting. These work very well in an abrasive environment
(I've actually used this setup on a grinder head that rides on two
parallel tubes) as they will just ride up and over deposits on the
shafting (and abrasive dust does like to stick to tubing) instead of
jamming like a groove would. Two of the common mass produced bearings that
you can buy cheaply in bulk would probably be cheaper/more cost effective
than a more specialized bearing too.

I considered it sometime ago. Unfortunately environment in which the
device
will be used
have some abrasive dust present.
Plus manufacturing cost will be too high because:
1. Turned, ground and polished shafts are expensive. Especially
stainless
ones.
2. Shafts must be absolutely parallel and at precise distance which
makes
the manufacturing expensive.
3. Making slide is an expensive due to the precision.

Thanks for suggestion anyway.

BTW The cheapest(but still too expensive for me) linear solution I found
was
from GUS.

Just buy some linear bearings and be done with it. Somebody figured
this
out a long time ago. Thompson bearings and shafts.
