Description

The Model 3 Rigid Caster is the matching rigid for the Model 3 Swivel Caster. The top plate is 2-3/8″ x 3-5/8″ with a 1-3/4″ x 3″, slotted to 1-3/4″ x 2-7/8″ for 5/16″ mounting bolts. This caster has a 3/8″ diameter bolt axle with a locking nut and features 1-1/4″ and 1-1/2″ wide wheels. This rigid caster is welded leg construction. Multiple wheels and brake options are available. When manually moving equipment supported by 4 swivel casters it can be tough to maintain the direction you are pushing or pulling. Rigid casters are primarily used to control direction when equipment is being moved in straight line travel. Equipment with rigid casters installed can not move sideways. Ideal for portable bar carts, beverage service stations, and hospitality supply trolleys. This plate caster is NSF listed. A Stainless Steel Model 3 version is also available for wet or corrosive environments.

This Polyolefin wheel is a solid one-piece injection molded wheel available in heavy duty flat tread or crown tread donut shaped configurations. Polyolefin is an industrial plastic material designed to resist chemicals, water, and mild acids. Bearing options include plain bore, sealed ball bearings. Roller bearings, or Delrin bearings. This hard material requires a smooth floor surface. Non-marking wheel with low initial cost. Cannot develop flat spots when parked for prolonged periods. Impervious to sterilization processes. Use above 32°F and below 180°F; not for freezers or heat applications like rack washers. Ideal for supermarkets, warehouses, and manufacturing plants.

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.
