Bearing

Symptom
Unable to lift a load.
Strange noise
Traveling motion of the Trolley (common for motorized/manual trolley)
Symptom
Unable to travel due to
slipping of wheel
Unable to travel due to
slipping of wheel, or unable
3
to travel in uniform motion
Sounds abrasion sound
when running on a
curved rail
Unable to travel on the

Cause
Sticking, Breakage Replace the bearing.
Deterioration Replace the bearing.
Cause
Inclination of Travel Rail Make sure that rail
gradient is within 1 degree.
Oil attachment on Wipe off the attached
running surface of the rail foreign matter.
Friction resistance Apply small amount of oil
between wheel and rail on the rail surface where
noise generates.
Interference of the trolley Make sure that the rail
and the curved rail curvature is larger than
the minimum turning
radius. (See P43, 48)
Pulling a load in an inclined
direction (floating wheel)
Defective gear Remove the stain and
engagement foreign matter on the
wheel and the gear.
Wrong adjustment of Check the number
collar of collars and their
assembled positions
Uneven abrasion of the Check the abrasion of the
wheel wheel
Deformation of wheel Check the distortion of
wheel and damage of
running surface
Deterioration of wheel Check if rolling noise
bearing sounds when the wheel
is rotating.
Deformation and Check the abrasion and
abrasion of the rail deformation of the rail.
Remedy Main factor
Use under hot
environment or
excessively frequent use
Use under hot
environment or
excessively frequent use
Remedy Main factor
Improper installation of
Travel Rail
Use under the
environment likely to
attach foreign matter
Use of the curved rail
of curvature less than
minimum turning radius
Operating method
—
Ambient conditions,
environment
Incomplete checking
Traveling on curved rail
or unevenness of running
surface
Excessively frequent
collision with stopper or
unevenness of running
surface
Expiry of service life
Over load or expiry of
service life
Countermeasure
Avoid using under hot
environment or excessively
frequent use
