Polyolefin Caster Wheels from Caster City

Polyolefin Caster Wheels are injection molded from a blend of thermoplastic polymers, forming a one-piece solid sanitary design that prioritizes durability and hygiene. These wheels are available with a plain bore, precision sealed ball bearings, roller bearings, or Delrin bearings for smooth operation across various light to medium-duty applications. As a cost-effective and lightweight option, polyolefin wheels are hard, non-marking, and non-conductive, offering superior resistance to water, chemicals, solvents, acids, grease, oils, and gasoline. Their unique composition ensures excellent abrasion resistance and impact absorption, making them a reliable choice for environments where sanitation and floor protection are essential.

Polyolefin Caster Wheels are particularly suited for wet and corrosive applications due to their outstanding resistance to most commonly encountered liquids, ensuring long-lasting performance. Their slightly crowned tread enhances rollability and maneuverability, and they do not develop flat spots when parked for extended periods. With a hardness of 65–70 Shore D, these wheels provide floor protection, low noise, and easy cleaning, while remaining impervious to sterilization processes. However, they can become brittle in cold, dry environments like refrigerated storerooms and should not be used in freezers or heat applications above 180°F during intermittent usage, such as rack washers.

Ideal for bakeries, food processing, dairies, meat packaging, laundries, supermarkets, warehouses, manufacturing plants, cleanrooms, medical facilities, and offices, these wheels excel where chemical resistance and non-marking performance are critical. Capable of handling impacts and loads up to 900 lbs per wheel depending on size, they offer economical mobility in harsh conditions. For reliable, sanitary, and floor-friendly caster solutions tailored to your needs, contact Caster City to explore custom configurations of our durable Polyolefin Caster Wheels.
