Use the Polyolefin ( Industrial Plastic ) wheel for "Standing
Loads". Polyolefin wheels eliminate the possiblilty of a flat spot developing
on the surfiace of polyurethane and rubber tires when the weight exceeds 2/3 of
the rated capacity when the object is left parked most of the time .
Threaded Stem Casters should NOT be used
as a "Leveling Device"! Capacity ratings are based on the weight being directly
on the swivel bearing.
You should never select on the
basis of load capacity alone. Capacity ratings do not take into account the
effort required to manually move a load. Capacity ratings are based on manual
operation under ideal conditions. If these casters are going to be moved by
mechanically powered equipment, consult us for a reduced capacity rating based
on your application.
