FLOOR SURFACES
A most important consideration. If your floors require maximum protection, select a resilient wheel. If you desire capacity only, choose a metal wheel. If you want capacity and floor protection, we recommend a Plexite and/or Polyurethane wheel.

FLOOR CONDITIONS
Are there metal chips? Harsh chemicals? Uneven surfaces? Elevator sills? Extreme heat or cold? if so, a metal wheel may be your best bet. For a complete review, please see our Wheel Selection Chart.

CAPACITY
We believe that it is wise to select "more caster than you think you need." Payson is a member of the Institute of Caster Manufacturers and subscribes to virtually all of its suggested load ratings. Each load rating is based upon a manual operation of 3 to 5 mph over even floors. Your selection should have a large enough wheel to ride over obstructions smoothly and to transport the load with minimum effort.

WHEEL BEARINGS
Although anti-friction Roller, Ball and Timken bearings don't necessarily increase the capacity, they make it easier to start and sustain motion. In addition, they are quieter. Plain, Delrin or Oilite bearings should be considered when the operation is intermittent and when the travel is short.

NSF (National Sanitation Foundation) CERTIFIED CASTERS
Many of Payson Casters light to medium heavy duty casters have been designated as certified by the National Sanitation Foundation. Casters in the 010, 020/021, 050/051, 070/071, 080 and 200/201 series are NSF certified. In addition. Payson's polyurethane, mold-on rubber, polyolefin, mold-on poly, hard rubber and cushion rubber wheels are NSF certified.
Please consult the factory for information on Payson's NSF certified items.
