Stem Casters are a type of caster wheel that mounts to equipment using a stem rather than a mounting plate and makes them ideal for applications with limited mounting space available. They come in various stem types including threaded, grip ring, expanding rubber, and metal (square/round). Each stem module type is designed to fit different tubing or frame structures and allow for smooth mobility. Stem Casters are most commonly used on carts, furniture, and medical equipment. We offer stem casters with load capacities as small as 250 lbs and as strong as 1,500 lbs, with many pedal and foot brake options available.
We have a stem caster for any need and if you cannot find the right caster, please contact us directly (Call: 800-501-3808 / Email: sales@castercity.com) and we can help you find the perfect stem and caster for your application.
We offer a wide range of caster wheels designed for various use applications, including light-duty furniture, industrial machinery, and medical equipment and more to suit your unique or different mobility needs.
Total locking brakes are a popular choice when safety and stability. We offer brakes on both stem and plate casters. These brakes are designed to lock both the wheel and the swivel at the same time, so once they’re engaged, the caster won’t roll, pivot, or move.
Total locks are widely used in a variety of settings such as warehouses, medical facilities, food service environments, and even heavy duty industrial settings. They’re the perfect caster for mobile equipment that needs to be rolled into place and then stay firmly in position carts, racks, prep tables, or mobile workstations.
If you’re not sure what kind of brake or caster setup works best for your home or business needs, our Caster City sales team is here to help. With decades of experience, we’ll guide you to the right solution for your application and make sure you get exactly what you need for the job.
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.
Caster City offers a wide range of office and furniture casters designed for smooth, quiet movement across carpet, tile, and hardwood floors. If you’re upgrading desk chairs, file cabinets, mobile workstations, or anything else your office needs our casters provide durability, ease of movement, and a professional finish that complements any office setup.

These casters and wheels ensure compatibility with various surfaces, with Polyolefin wheels recommended for standing loads to prevent flat spots.
TPR (Thermoplastic Rubber) is a non-marking, injection-molded blue rubber mechanically bonded to a polyolefin core in the RHB High Capacity Soft Blue Rubber wheels. It’s elastic, tear-resistant, and quieter than polyurethane, providing shock absorption and floor protection for hospitals, labs, and food service. It resists light chemicals but may develop flat spots under prolonged loads.
The non-marking blue TPR wheels on the Stem Caster Model K3A roll quietly, absorb shock, and protect floors like tile or linoleum, making them perfect for hospital carts or beds. They’re NSF-listed and ideal for dry institutional settings, preserving equipment and floors.
Yes, the blue TPR tires resist many chemicals and solvents, suitable for dry lab environments. Harsh chemicals or heat buildup may weaken the tire’s bond to the polyolefin core, so avoid heavy exposure.
TPR wheels need more effort under load. For manual pushing, reduce the 350 lbs per wheel capacity by 50% (to 175 lbs) and select the 5” diameter for easier movement on smooth, dry factory floors.
No, avoid prolonged standing loads. The blue TPR tires can develop flat spots or a permanent “set,” reducing performance in institutional settings like schools or food service.
