x Avoid using shaft keys when possible. Although ClearPath
includes a keyway feature on the shaft, Teknic does not
generally recommend the use of keys. Keys tend to cause run-
out and backlash errors, particularly in reciprocating, precision
positioning motion applications.
However, keys should be considered for use in
applications where coupling slip could result in a dangerous or
hazardous condition. Also, key use may be appropriate for
unidirectional applications (where the motor always spins in the
same direction) as these applications are less prone to key-
related lash problems.
x Avoid direct loads. In general, ClearPath motors are not
designed for connection to direct loads (e.g. direct connection to
a grinding wheel). However, direct connection may make sense
if the load is of low-mass and balanced, as with small mirrors
for laser applications.
