This Revvo 150 RU15 6" rubber and cast-iron wheel has an 810-lb. load capacity and a 20 mm bore. It has a painted cast-iron hub with a roller bearing for radial load support with a hub length of 2-3/8", and 1-3/4" wide rubber tread for floor protection and for quiet movement along surfaces. The wheel has an operating temperature range from -58 to +167 degrees F and a Shore hardness range from A83 to A87. It measures 6 x 1-3/4 inches (Dia x W). (Dia is diameter, the vertical distance from top to bottom; W is width, the horizontal distance from one side of the tread to the other.) This rubber and cast-iron wheel is suitable for use in industrial material handling applications and in other settings where rough conditions are common.
Caster wheels are the rolling part of casters, which are wheeled mechanisms used to support and maneuver objects such as carts, racks, and dollies for material handling applications in many industries. Caster wheels may be single or dual (also called twin), and they are made from a variety of materials. Generally, wheels with hard tread material have a higher load capacity and roll easier than soft tread wheels, which provide quieter operation and cushioning.
Revvo Caster manufactures casters and wheels for material handling, OEM products, and industrial production. The company, founded in 1997, is headquartered in West Seneca, NY.
