oil seal may wear and thereby cause oil leaks. This is particularly evident when chemicals
are used. Chemicals can also cause andor accelerate rust and corrosion. When using
your SANDEX unit in dusty areas, you should consider using protective covers made from
stainless steel or plastic.
If the location for your SANDEX unit is very dusty, the air outlet in the oil
fill port may become an entrance into the housing. Placing an air filter over
this port should prevent dust from entering the housing. Electrical currents
If electricity passes through the SANDEX unit, minute dimples can occur on the cam
followers and roller gear cam, as well as on the rolling surfaces and members of the
bearings.
““Electrolytic corrosion” is where electrical sparks actually melt away the surfaces of
the rolling members. Electrolytic corrosion is a current-based effect. Therefore, it can
occur under less than one volt of electrical power.
If your SANDEX unit may be subject to electrical currents, make sure to insulate it.
Electrolytic corrosion, if allowed to persist, will increase the amount of vibration and noise,
and eventually render your SANDEX unit useless. Always insulate the table and unit from
welding applications or other automated machinery that use large amounts of electrical
current.
When linking the motor with the input system, consider using rubber couplings instead
of metal types. Rubber provides more insulation. Other measures that can prevent
electrolytic corrosion include using V-belts and timing belts.
