StemCaster Model K3

Capacity up to 300 pounds per caster. These institutional stem casters are ideal for most types of institutional equipment, and are offered with a wide
selection of wheels.

Use the Polyolefin ( Industrial Plastic ) wheel for “Standing Loads”. Polyolefin wheels eliminate the possibility of a flat spot developing on the surface 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.

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
