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.

6″ Orange Crown Tread Polyurethane on Aluminum Wheel.
The Polyurethane on Aluminum (UAO/UAC) Caster Wheel in the Stainless Steel Kingpinless Stem Caster Model G15 is a great choice for heavy-duty institutional needs in labs, hospitals, and food processing plants, especially in sanitary applications where washdowns and corrosion resistance are critical. This wheel features a flexible polyurethane crown tread on aluminum, made in 2” wide with 4”, 5”, 6”, and 8” diameters, holding up to 1200 lbs per wheel at room temperature on smooth floors, with a durometer of 90A, offering a semi-cushioned ride that can climb over small debris, door jambs, and expansion joints. It rolls easier than the same size conventional rubber caster wheel, protecting floors better than metal wheels, and its aluminum hub is lighter than standard polyurethane on iron wheels, resistant to rust and corrosion, and provides a higher aesthetic value. The wheel includes precision sealed ball bearings with top hat spanners for a 1/2” axle, ensuring smooth rolling in demanding settings.
The stainless steel kingpinless caster assembly, made from 304 stainless steel with a hot-forged stamped steel construction and ¼” thick legs welded to the precision machined swivel bearing, offers easier swivel rotation, reduced vibration, and longer trouble-free performance for manually moved equipment, with lubrication fittings for movable parts and a larger swivel radius on 6” and 8” wheels to reduce shimmy vibration. The caster includes standard wheel brakes and swivel locks for secure positioning, making it ideal for sanitary applications like food processing or pharmaceutical labs where NSF and ROHS compliance is essential. The crown tread on the polyurethane wheel enhances ergonomics by reducing push-pull forces and the effort needed to change directions and start motion, improving user comfort and efficiency during operation. Note that threaded stem casters should not be used as a leveling device, and capacity ratings are based on the weight being directly on the top of the swivel bearing, not above it on the threaded stem.
These polyurethane on aluminum wheels withstand impacts and heavy loads while changing directions efficiently due to their large crown tread, but the bonding agent holding the polyurethane tire to the aluminum center can be affected by exposure to some chemicals, impact, overloading, or heat buildup from continuous usage, potentially weakening the chemical bonds if used in such conditions. They offer higher capacity while still providing some floor protection compared to hard composition wheels, making them a smart pick for heavy-duty sanitary applications needing to support heavy loads without damaging floors. The stainless steel assembly ensures durability and corrosion resistance, giving reliable performance in wet washdown settings like hospital kitchens or labs, making this industrial kingpinless stem caster a great fit for equipment needing stability, reduced vibration, and mobility in institutional environments.
The Stainless Steel Kingpinless Stem Caster (SS-G15) is a heavy-duty industrial caster designed for reliability in sanitary and high-precision environments, such as food processing and pharmaceutical labs. Constructed from 304 stainless steel with a welded, stamped steel design and ¼” thick legs welded to a precision machined swivel bearing, the SS-G15 ensures smoother swivel rotation, reduced vibration, and extended trouble-free performance for manually moved equipment. Its kingpinless design, combined with lubrication fittings for all movable parts, enhances durability and ease of maintenance, making it ideal for washdown settings requiring NSF and ROHS compliance. With load capacities ranging from 250 lbs to 1,500 lbs depending on wheel type, the caster is optimized for infrequent manual movement with the weight applied directly on the swivel bearing, not above it on the threaded stem, and should not be used as a leveling device.
The SS-G15 offers exceptional flexibility with a variety of wheel options and configurations to suit diverse applications. Available wheel diameters include 4”, 5”, 6”, and 8” with a 2” tread width, and materials range from gray soft rubber (flat or crown), high-capacity rubber, and self-energizing ergonomic polyurethane (crown, orange) to polyolefin, nylon, phenolic, and ultra-high-capacity polymer. Most wheels feature stainless precision ball bearings for smooth operation, with specialized options like 90A orange polyurethane on aluminum or 65D blue polyurethane on aluminum (6” and 8” only). The crown tread design on polyurethane wheels reduces push-pull forces, minimizing the effort needed to start motion or change directions, thereby improving customer comfort and operational efficiency in institutional settings.
For secure positioning, the SS-G15 includes standard wheel brakes and swivel locks, with additional braking options such as the Top Lock Brake (TB) with a pedal on the side of the wheel and the Bolt-On Universal Face Contact Brake (UFCB). These features ensure stability for equipment like carts, tables, or workstations during cleaning, sterilization, or setup in hospitals or labs. The precision machined combination load and thrust bearing enhances smooth operation, making the SS-G15 a trusted choice for safety-focused environments. To select the appropriate configuration, customers should contact Caster City at sales@castercity.com or 800-501-3808 for recommendations, as real-world conditions may vary and capacity ratings alone are not sufficient for optimal performance.
