Industrial Casters
Industrial casters are wheel assemblies which are attached to the
bottoms of industrial furniture legs to provide mobility and shock absorption. They are used on chairs, tables and storage racks in schools, hospitals, banquet halls, restaurants,
retail stores, truck garages and industrial manufacturing plants and
warehouses. Chair casters are one of the most common types of industrial casters. Being able to roll tables, chairs and equipment
platforms around smoothly is important in manufacturing warehouses, where
equipment, workstations and chairs are frequently moved around the facility. It
is also very important in hospitals, where computer stations, beds, IV racks
and other equipment are constantly in transit.
Industrial caster applications require heavy duty casters which
can withstand heavy loads, uneven floor surfaces and being jarred against
ledges. For this reason, industrial furniture casters are fabricated from
stamped steel housings and brackets, aluminum or cast iron wheel centers and
axle nuts and thermoplastic rubber or tread polyurethane caster wheels. Some
caster assemblies are two-wheeled, providing a broader, more stable support for
heavy equipment. Medical and hospital furniture casters are medium-duty with
soft rubber of polyamide wheels and polypro injection molded housings for
smooth, quiet operation. Office and household chairs are made from lower-duty
thermoplastic materials, although bed casters typically have strong metal
housings.
