the swivel bearing when a swivel caster is rolling or turning.
|4. The softer the wheel material, the more
resilient it is but the risk of a flat spot developing is higher if left parked
for a prolonged period with a load greater than 50% of the wheel capacity.
|5. Soft rubber tires are the most floor
protective wheel material. Chair casters with Polyurethane tires are safe to
use on hard floor surfaces such as hardwood, ceramic tile, concrete floors and
plastic mats. They are NOT recommended for use on soft wood floors, vinyl or
linoleum. For Industrial applications, Polyurethane is often described by
others as floor protective. It is non-marking and non-marring; however, a hard
polyurethane may affect some floor surfaces over time.

only, less than 10% chemical concentration.
