Description
The Stainless Steel Model 9 Caster with PB Polyolefin Wheel is a stainless steel industrial caster built for wet and corrosive environments where hygiene and durability are needed. It’s made from 1/2” thick 304 stainless steel with a 5/8” bolt and nut kingpin welded together to handle manual use, featuring two rows of ball bearings for axial and thrust loads, lubrication fittings in the swivel bearing and 1/2” stainless steel axle, and brake options like swivel lock or total lock. The rig supports up to 1200 lbs per caster, with a mounting plate of 4″ x 4-1/2″ (bolt hole pattern 2-5/8″ x 3-5/8″ to 3″ x 3″), for use in settings like food processing plants and labs.
This caster uses a 2” wide PB Polyolefin Wheel, a one-piece injection-molded wheel with a flat tread, available in black, in 4”, 5”, 6”, and 8” diameters, supporting up to 800 lbs per caster. The polyolefin material resists water, chemicals, mild acids (below 10% acid content), grease, and oils, with a temperature range of 32°F to 180°F, and a Shore D 65 durometer, making it non-marking and resistant to flat-spotting during prolonged parking. It fits a 1/2” axle bolt with bearing options like roller, Delrin, or stainless precision sealed ball bearings, but it’s not suited for shock, overloading, abuse, obstructions, poor floors, freezer use, or high-heat applications above 180°F intermittent usage.
The Model 9 is used in research labs, hospitals, food service, schools, and bakeries for its corrosion resistance and floor protection, meeting NSF and ROHS standards with an electrolytic finish for smoothness. It’s designed for wet settings like fisheries, cruise ships, and autoclaves, but for mechanically powered or abusive applications, the Stainless Steel Model G15 (up to 1500 lbs) is recommended. Available online at Caster City with a fast lead time, this stainless steel caster fits institutional needs; contact Caster City at 800-501-3808 for ordering assistance.

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.

The 304 stainless steel frame resists rust and chemicals, perfect for washdowns, and meets NSF and ROHS standards.
What is the load capacity of the Stainless Steel Caster Model 9?
The Model 9 supports up to 1200 lbs per caster, but it depends on the wheel you pick. It’s rated for manual use on smooth floors, no steep inclines over 3 degrees, and speeds under 3 mph.
What bearing options are available for the Stainless Steel Caster Model 9 with PB Polyolefin Wheel?
For the Model 9 stainless caster with PB Polyolefin Wheel, you can choose roller bearings (R), Delrin bearings (D), plain bore (P), ball bearings (BB), precision sealed ball bearings (PS), stainless precision sealed ball bearings (SPS), or stainless steel roller bearings (SSR). These let you customize for wet environments.
Why choose the PB Polyolefin Wheel for the Stainless Steel Caster Model 9?
The 304 stainless steel frame resists rust and chemicals, making it great for wet spots with frequent cleaning. The polyolefin wheel handles water, mild acids (below 10%), grease, and oils, so it fits labs and food service well, but skip it for high-acid stuff.
