Stainless steel casters, offered in both plate and stem mounting styles, are built for use in wet, corrosive, or high-temperature environments where durability and cleanliness are critical. These casters are available in both 304 and 316 stainless steel—the former offering strong corrosion resistance for general industrial and food service use, and the latter providing superior protection against harsh chemicals and saltwater, making it ideal for marine and pharmaceutical applications. Designed to handle temperatures up to 450°F when paired with high-temp wheels and raceway seals, these casters perform reliably in extreme heat such as in autoclaves or commercial ovens.
Caster City’s stainless steel casters are built with longevity and performance in mind. Each unit includes a grease fitting in the swivel bearing for easy maintenance, protective seals, and a dust cover to guard internal components from contaminants. Whether you choose 304 for its broad utility or 316 for its maximum corrosion resistance, these casters ensure smooth, low-maintenance mobility in the most demanding conditions.
These industrial pneumatic casters feature air filled pneumatic wheels. These industrial casters are designed for low speed manually moved applications only. Air filled pneumatic wheels provide a cushioned ride, shock absorption and quiet operation. Pneumatic casters are ideally suited for moving fragile or delicate cargo where caster overall height is not critical. Casters with pneumatic wheels are usually the best choice for use outdoors over rough surfaces ( i.e. gravel ) or on grass. The wide footprint on 8″ or larger pneumatic wheels provides stability on gravel and does not sink into lawns.
Pneumatic casters and pneumatic wheels are also popular for indoor use in places such as hospitals, scientific and electronic laboratories, hotels, department stores and TV or movie studios.
Pneumatic wheels with black tires do not mark the floor as long as the wheel is allowed to roll. Changing directions without allowing a swivel caster to turn gradually around, or dragging a black rubber wheel sideways, can mark some floors.

Key Features and Specifications
Why Choose the “RT” Autoclave Wheel? The “RT” wheel stands out in environments where standard casters fail. Unlike phenolic or epoxy resin wheels, which work better in dry heat, this wheel excels in moist, high-temperature settings. Autoclaves, used in medical and pharmaceutical industries, sterilize equipment with steam and pressure. The “RT” wheel withstands these conditions without breaking down. Its high-temperature plastic material stays strong against corrosive substances like cleaning chemicals, oils, and acids. This makes it a top choice for facilities that need reliable, hygienic, and durable casters.
In food processing, the wheel supports equipment like carts and racks in wash-down areas. The white color shows dirt clearly, so staff can clean quickly to meet sanitary rules. Laboratories benefit from the wheel’s resistance to solvents and its lightweight design, which makes moving heavy equipment easier. Medical facilities use these wheels on beds, carts, and sterilization units, ensuring smooth operation even after repeated steam cycles. The “RT” wheel’s non-marking feature protects floors, and its stainless steel bushing ensures a secure fit on axles, reducing wear over time.
How It Works The “RT” wheel’s high-temperature plastic is engineered for tough conditions. In an autoclave, steam and pressure sterilize tools and equipment. Normal wheels might crack or degrade, but the AC wheel maintains its shape and resists moisturized heat. Its propietary blends of plastics and fiberglass and heat-resistant polymer additives resists water, so it won’t swell or weaken in wet environments. The stainless steel spanner bushing ensures a tight fit on the axle, preventing wobbling or detachment under heavy loads. With a 350-pound capacity per wheel, four wheels can support up to 1400 pounds total, making it suitable for heavy carts or racks.
The 1.25-inch width balances stability and maneuverability. The wheel’s design reduces friction, allowing smooth rolling even on wet or uneven surfaces. Its abrasion resistance means it won’t wear down quickly, even with frequent use. The white color isn’t just for looks—it helps staff spot dirt or contaminants fast, which is critical in food and medical settings where cleanliness is non-negotiable.
Benefits Over Other Wheels Compared to standard caster wheels, the “RT” Autoclave Wheel offers unique advantages.
