Rubber on Iron

Heavy duty casters are designed with a kingpin in the swivel with a double row ball bearing for smooth turning. This series features 3″ wide wheels increasing the load capacities on these casters. These casters have 4-1/2″ x 6-1/4″ top plate providing a strong support structure for the item these are mounted to. Moldon Rubber Wheels (aka – Rubber on Iron) are a dynamic and durable wheel offering which can be a great fit for many applications. These wheels are designed with a Moldon Rubber tread bonded to a cast iron core which are usually both black in color. These wheels are quiet in operation and absorb shock and vibration well. They help prolong equipment life and protect cargo. One downfall is these wheels can be difficult to push/pull when loaded close to their capacity due to flat-spotting on the wheel tread.
