Description
4″ Polyurethane.Swivel Bearing Seal & Grease Fitting. Shown in photo with 5″ wheels. This Model 3 stainless steel stem caster is formed from 304 stainless stamped steel. This stainless steel stem caster uses a ⅜” diameter axle and the swivel caster raceway is held together by a ½” diameter rivet. The stainless steel stem caster’s brackets hold two rows of balls which change direction more easily. There is a solid cover over the swivel raceways to shield them from dirt and dust. The Stainless Steel Stem Caster Model 3 performs best if you limit the load to no more than 1000 lbs on a set of 4 Model 3 casters.
This solid all polyurethane industrial caster wheel was developed for sanitary and washdown applications, and is capable of rolling indoors or outdoors. The blue all polyurethane (“AP”) caster wheel is manufactured in 1-¼” wide and with diameters ranging from 3”-5”. Caster City manufactures this 1-1/4″ wide (“AP”) blue all polyurethane wheel to come with a steel spanner bushing which is available in stainless steel as well upon request. The temperature range of this industrial caster wheel is -50°to 180° F and the durometer of the polyurethane is Shore 60D.
These wheels are non marking and non conductive. The absence of a metal center eliminates bond failure as a cause for wheel replacement. These caster wheels are especially suited for use with stainless steel casters in wet and corrosive applications. They are designed for use in Pharmaceutical Laboratories, Hospitals, and Food Processing Plants – wherever a clean sanitary design is desired. These wheels are not recommended for applications involving shock, overloading, abuse, obstructions, poor floors, or for storage (standing) loads.
These wheels are designed for use in a wet environment and they eliminate the possibility of tire separation.

FAQ
Stainless Steel Swivel Stem Caster Model SS-3 with 1.25-Inch Wide AP Solid All Polyurethane Wheel
What material is the AP Solid All Polyurethane Wheel made from in the Stainless Steel Swivel Stem Caster Model SS-3?
The AP Solid All Polyurethane Wheel in the Model SS-3 swivel stem caster is a one-piece solid polyurethane wheel with a Shore 60-65D durometer, designed for non-marking performance and washdown suitability due to its smooth, non-porous surface.
What applications are best for the light-duty stainless steel stem caster with AP Solid All Polyurethane Wheels in institutional settings?
This light-duty stainless steel stem caster with AP Solid All Polyurethane Wheels is perfect for pharmaceutical labs, hospitals, and food processing plants in institutional settings, where a stem mount caster moves carts or tables on smooth floors in washdown environments, ensuring no water or contamination collects on the wheel surface, with an optional total lock brake for stability.
What bearing type comes with the AP Solid All Polyurethane Wheel in the Model SS-3 light-duty stem caster?
The AP Solid All Polyurethane Wheel in the Model SS-3 light-duty stem caster comes with a plain bore for a 3/8” axle, using either stainless steel or delrin spanners for smooth rolling in institutional applications.
Can the AP Solid All Polyurethane Wheel in the Model SS-3 light-duty stainless steel stem caster roll on rough floors?
No, the AP Solid All Polyurethane Wheel in the Model SS-3 light-duty stainless steel stem caster is designed for smooth floor surfaces only—rough floors or obstructions will damage these stainless steel casters and shorten their lifespan.
Are the stainless steel stem casters with AP Solid All Polyurethane Wheels in the Model SS-3 good for standing loads?
No, the stainless steel stem casters with AP Solid All Polyurethane Wheels in the Model SS-3 are not ideal for standing loads—prolonged static loads should be avoided to prevent potential damage to the wheel.
How do I protect the AP Solid All Polyurethane Wheel in the Stainless Steel Swivel Stem Caster Model SS-3 from damage?
Protect the AP Solid All Polyurethane Wheel in the Model SS-3 stem caster by avoiding shock, overloading, abuse, obstructions, or rough floors, ensuring its performance in washdown environments.
Do the AP Solid All Polyurethane Wheels in the Model SS-3 light-duty stem caster leave marks on floors in institutional settings?
No, the non-marking design of the AP Solid All Polyurethane Wheels in the Model SS-3 light-duty stem caster is perfect for protecting floor surfaces in hospitals, labs, or other institutional settings.
Why are the stainless steel stem casters with AP Solid All Polyurethane Wheels good for institutional washdown applications?
The stainless steel stem casters with AP Solid All Polyurethane Wheels are designed for washdown applications as the wheel’s smooth, non-porous surface prevents water or contamination from collecting, resisting chemicals, oils, and solvents, with the stainless steel assembly ensuring corrosion resistance, making them a practical choice for institutional settings.
What’s the load capacity and temperature range for the AP Solid All Polyurethane Wheel in the Model SS-3 light-duty stem caster, and how do I handle high-temperature applications?
The AP Solid All Polyurethane Wheel in the Model SS-3 light-duty stem caster supports up to 350 lbs per wheel and operates from -20°F to 180°F; the caster can handle up to 400°F due to its raceway seals, with the TL and TB brakes being high temp compatible—consult Caster City for extended high-temp use beyond the wheel’s limit.
What brake options are available for the Stainless Steel Swivel Stem Caster Model SS-3 with AP Solid All Polyurethane Wheels?
The Model SS-3 offers three stainless steel brake options: the Total Locking Brake (TL) to lock both wheel and swivel (high temp compatible), the Top Lock Brake (TB) with a metal pedal on the side (high temp compatible), and the Plastic Top Lock Brake (PTB) with a plastic pedal behind the wheel (not high temp usable due to the plastic pedal).
What stem types are available for the Stainless Steel Swivel Stem Caster Model SS-3 with AP Solid All Polyurethane Wheels?
The Model SS-3 is compatible with grip ring stems, threaded stems, round stems, square stems, stems with cross holes (both round and square), and expanding rubber stems, providing versatile mounting options for institutional equipment like carts or tables in labs or hospitals.
Why is the optional total lock brake on the Model SS-3 stem caster with AP Solid All Polyurethane Wheels important for safety in hospital or lab settings?
The optional total lock brake on the Model SS-3 stem caster locks the swivel and wheel, fully immobilizing the stainless steel assembly to prevent movement of objects—like carts, tables, or lab equipment—when someone leans on them during tasks such as working, cleaning, or setup, ensuring safety in hospital or lab environments. Total locking casters are important because in cutting, welding, sawing, or similar tasks, people will lean against the worktable while doing their dangerous cut, and the total lock caster prevents anything in the caster from moving, totally immobilizing wheel and swivel rotation.
What makes the Model SS-3 light-duty stainless steel industrial stem caster a trusted choice for institutional applications in wet settings?
The Model SS-3 light-duty stainless steel industrial stem caster is a trusted choice for wet institutional settings due to its 304 stainless steel construction, NSF and ROHS compliance, raceway seals for high-temp use up to 400°F, zerk fitting, and dust cover for the swivel bearing, offering corrosion resistance and durability for washdown environments like labs or hospitals.
How does the Model SS-3 light-duty stainless steel industrial stem caster enhance stability for lab or hospital equipment in institutional settings?
The Model SS-3 light-duty stainless steel industrial stem caster enhances stability for lab or hospital equipment with its double ball bearing swivel for smooth rotation, raceway seals and dust cover for durability, and brake options like TL, TB, and PTB to secure equipment—like carts or tables—firmly in place during operations, ensuring safety in institutional settings.
