Colson Performa Wheel Flat Grey Tread with Capacity to 325 poundsPerforma wheels offer the advantages of both hard and soft tread materials in a single wheel. Like a hard tread wheel, Performa rolls easily and is very durable. Like a soft tread wheel, it rolls quietly, protects floors and resists impacts with a cushion ride. It also features maximum weather-ability, low temperature flexibility, resistance to chemicals, water and steam, and rejects floor debris such as metal shavings. Non-marking thermoplastic elastomer tread is permanently bonded to a ribbed polyolefin wheel core.

PERforma Conductive

Colson Performa Conductive Wheel Flat Grey Tread with capacity to 250 poundsPerforma Conductive wheels combine a soft cushion ride with a non-marking tread design. All wheels feature a cushion grey Performa tread bonded to a black Polyolefin wheel core. Performa Conductive wheels have been rigorously tested and approved by an independent lab and meet the requirements of federal specification FF-C-88C. This specification requires an average electrical resistance of less than 250,000 ohms.


Colson Polyolefin Wheel with capacity to 300 poundsDesigned for hard impacts and heavy loads, this wheel is injection molded from an exclusive Colson polyolefin compound. The unique ribbed design adds strength. Very light in weight, yet the impact strength of this wheel is far superior to hard rubber wheels. It offers superior resistance to most oils, chemicals, grease, gasoline, cooking fats and acids. In addition, the wheel is stain resistant, non-marking and provides zero water absorption.


Colson Thermo wheel with capacities to 1100 poundsThermo wheels feature a standard operating temperature range from -70°F (continuous service) to +525°F (intermittent service, +480°F continuous service). These wheels are molded from an exclusive engineered resin compound that offers non-marking floor protection, near zero water absorption, high load capacities and long service life. A special manufacturing process enables the wheels to retain a consistent bearing bore even when exposed to elevated temperatures. Furthermore, Thermo wheels are 100% recyclable, and they are highly resistant to animal fats, vegetable oils and salt solutions. The life expectancy of Thermo wheels is three times longer than high-temp phenolic wheels, and they offer an equal load capacity. Unlike high-temp phenolic wheels, Colson Thermo wheels have no outer skin that can break and absorb water or other fluids.


Colson ThermoTech wheels with capacities to 250 poundsColson ThermoTech Wheels feature a rubber tread that can take the heat. They are quiet and non-marking for superior floor protection. The rubber tread is an advanced technology rubber compound bonded to an aluminum core.

Polyurethane HI-TECH

Moldon Polyurethane HI-TECH Wheel with capacity to 300 poundsPolyurethane tread is bonded to a polyolefin core. Tread is molded in, around and through a ribbed extension of the core to prevent debonding. Standard colors are maroon tread on grey core. This is a very attractive, all purpose wheel. Resistant to most chemicals, solvents, water and acids.

Cast Iron

Colson Cast Iron wheel with capacity up to 600 poundsThis wheel should be specified when excessive load weights are involved and floor protection is not a factor. Its high strength withstands sharp impacts. Cast Iron wheels should not be used if noise is of major concern or if loads are fragile.

Rubber HI-TECH

Colson Rubber HI-TECH Wheel with capacity to 150 poundsRubber HI-TECH wheels are made of a thermoplastic cushion rubber tread bonded to a rugged polyolefin core, with capacities to 150 pounds each.


Colson Phenolic wheel for 2 Series Casters with capacity up to 300 poundsPhenolic resin wheels are filled with macerated fabric. This wheel provides quieter operation than steel or aluminum, provides superior floor protection, and resists hard impacts, most chemicals and steam. The standard color is black.
