Hey folks, just heard some information about radial and
axial loads on the shafts for these cool little gearmotors.
Kinda verifies exactly what Dave Anderson and his buddy had
already mentioned, so here it is. Hope this helps.
Quoted :
>Sleeve bearings are really not capable of supporting large
radial loads, and >virtually no axial load. The actual
radial load capability depends on a number of >factors, but
is typically on the order of a couple of pounds.
>We do offer ball bearings as an option on the output in
place of the sleeve >bearing. This greatly increases the
load capability. Again, the exact values >depend on a
number of factors and are somewhat subjective. For our
standard >ball bearing for this unit type, we would
typically recommend less than about 8 lbs >radial load and
less than about 2 lbs axial load.<
