Choosing the Right Caster Series

Our caster series is a combination of many factors, including top plate and height measurements, wheel diameter, width and material, bolt hole pattern, weight capacity, and caster type. Weight capacity is categorized as medium duty casters (< 900 lbs), medium heavy duty casters (900-1500 lbs ), heavy duty casters(1500-4500 lbs), extra heavy duty casters (5,000-20,000 lbs) and super heavy duty casters (> 20,000 lbs ).
