Cast iron/semi
steel - These wheels are abrasion resistant and are easy to start rolling.
Cast iron/semi-steel wheels are ideal for use on concrete and smooth steel, and
are resistant to extreme temperatures. They are also a good choice for
environments containing oil and grease, animal fats, metal chips, and mild
chemicals.
Steel - Forged
steel or ductile steel caster wheels
are an ideal choice when floor protection is not an issue and in situations
where loads are too heavy for floor protective wheels. Forged steel wheels
provide the best impact strength, ease of movement, and greatest load capacity
of all caster wheels.
Nylon - Glass
filled nylon wheels are extremely heat resistant, up to 490 degrees continuous
or 550 degrees intermittent. Nylon wheels are also durable, resist hard
impacts, are non-marking, and are resistant to cleaning agents as well as oils
and greases.
Rubber - When
you need a higher load capacity than soft rubber wheels, hard rubber wheels are
a good choice. They are extremely durable and won't flatten while sitting under
loads. Hard rubber wheels are also durable and have fluid ease of movement. However,
they are not non-marking.
Phenolic - These
wheels are constructed of phenolic resin and macerated canvas. Phenolic wheels
are commonly used for push/pull applications. In addition to being ideal for
high weight loads and being resistant to extreme temperatures, they are also
economic.
Pneumatic - Pneumatic
wheels are air-filled, offering high floor protection as well as the ability to
easily roll over obstructions. The wheels also provide shock absorption and
cushioning, making them ideal for fragile loads.
These are just a few of the many types of caster wheels
available.
