Selecting a Caster Load Rating Each Haydock caster and wheel carries a maximum recommended load capacity, based on manual operation with intermittent service at speeds of two miles per hour. Haydock load ratings are in accordance with Institute of Caster and Wheel Manufacturers (ICWM) recommendations. Wheel Size and Tread Hardness Generally, larger diameter wheels roll easier and absorb shock better than smaller wheels. Wider wheel treads spread load for better floor protection but are harder to roll than narrow treads. Hard tread wheels have higher load capacity and roll easier than soft tread wheels which provide a cushioned ride and quiet operation. Floor Conditions Soft tread wheels protect floors and offer quieter operation, though they are less suited for carpeted areas. Hard tread wheels are ideal for industrial locations where metal debris, steel grating, rough floors, and similar conditions exist. Installation Installation is simple, with a variety of standard plate and stem mounts available to meet specific customer needs. Finish Most Haydock standard casters come in a variety of colors and finishes.  If the Catalog does not show the finish that you are looking for, please contact the factory as other finishes are available upon request. Swivel Design Haydock casters are available in a single race swivel, dual race swivel or rigid construction.  The dual race swivel features two sets of  polished steel balls travel- ing in two lubricated raceways, providing maximum swivel radius, load capacity and long life.
