4″ Ultra Premium Orange Polyurethane w/ Crown Tread – Plate Rigid Caster K3
$25.78
Technical Specifications















Description
The UXY wheel features liquid cast polyurethane molded onto a precision-machined aluminum hub, offering exceptional durability and performance in a compact 1.25″ wide design. Available in 3″, 4″, and 5″ diameter options, this institutional-sized wheel provides smooth, quiet operation while maintaining impressive load capacity. The liquid cast polyurethane tread delivers superior shock absorption and roll-ability compared to injection-molded alternatives, making it ideal for applications requiring reliable performance and floor protection, and most importantly heavy applications that move infrequently. Each wheel comes equipped with dual precision sealed ball bearings to ensure consistent, maintenance-free operation for many years.
The UXY wheel’s unique liquid-cast polyurethane formulation delivers exceptional performance through its rapid rebound characteristics, significantly reducing the force (known as draw bar pull) required to initiate and maintain movement under load. This rapid rebound action allows the wheel to quickly recover from compression, maintaining optimal contact with the floor surface while minimizing rolling resistance. Unlike conventional wheels that may deform and create increased drag under heavy loads, the UXY’s specialized compound actively assists movement by converting potential energy from compression into forward momentum. This dynamic response not only reduces operator fatigue but also ensures consistent performance across varying load conditions, making it an ideal choice for applications where ergonomic considerations are paramount.
Matching rigid caster for Plate Caster Model K3. The mounting plate is 2 3/8” x 3 5/8” and the hole pattern is slotted to: 1 3/4” x 2 7/8” – 3” and is designed to use a mounting bolt size of 5/16”. This rigid caster uses a ⅜” diameter axle and nut and uses 1-¼” and 1-½” wide wheels. Multiple wheels and brake options are available. When manually moving equipment supported by 4 swivel casters it can be difficult to control the direction you are pushing or pulling. Rigid casters assist in controlling equipment being moved in straight line travel. Equipment with rigid casters installed can not move sideways. This plate caster is NSF listed.
Caster City manufactures this plate caster in Stainless Steel. Caster City also manufactures this plate caster in Economy Stainless Steel. Both 304 Stainless Steel casters are NSF listed and RoHS Compliant.

With a 1.25” tread width, 3”, 4”, or 5” diameters, dual precision sealed ball bearings, and 350 lbs capacity, this industrial caster is NSF-listed, ideal for heavy, infrequent-movement applications in hospitals, labs, or food processing plants.
Why choose these industrial casters for sanitary settings?
This light duty industrial caster combines a shock-absorbing, non-marking UXY Wheel with a corrosion-resistant swivel plate caster or rigid plate caster bracket, supporting 350 lbs. NSF-listed for dry or wet settings, it’s perfect for casters and wheels in hospitals, food service, or labs, protecting floors and reducing operator fatigue.
How does the UXY Wheel’s ergonomic design enhance this swivel plate caster?
The UXY Wheel’s fully crowned tread and self-energizing polyurethane reduce push/pull forces and vibration, paired with the swivel plate caster’s smooth swivel action for ergonomic movement. This caster is ideal for heavy carts in hospitals, labs, or food processing on smooth floors.
How do these casters and wheels protect floors in sensitive environments?
The non-marking UXY Wheel in this plate caster absorbs shocks and protects floors like tile or linoleum, with the light duty industrial caster’s sturdy bracket ensuring controlled movement in hospitals, labs, or food service, preventing floor damage.
How easy is it to roll the Plate Caster Model K3 with UXY Polyurethane on Aluminum Wheel?
This industrial caster rolls effortlessly at 350 lbs capacity due to the UXY Wheel’s liquid-cast polyurethane, fully crowned tread, and dual precision sealed ball bearings, enhanced by the swivel plate caster’s maneuverability, perfect for infrequent moves in labs or hospitals.
Can these casters and wheels be parked under load?
Avoid parking under loads exceeding 70% of the 350 lbs capacity (245 lbs) for long periods to prevent flat spotting. The plate caster’s polyurethane wheel ensures reliability for heavy, stationary equipment in food processing or labs when used cautiously.
Are these light duty industrial casters suitable for rough floors?
No, the UXY Wheel in this light duty industrial caster is designed for smooth, dry or wet floors without obstructions. It’s ideal for casters in sanitary settings like hospitals, labs, or food processing plants, not rough or abusive environments.
Can the Plate Caster Model K3 with UXY Wheel be used in washdown environments?
Yes, the UXY Wheel is washable, and the stainless steel plate caster option ensures full washdown compatibility for industrial casters in food processing or labs. The zinc-plated frame may rust in wet conditions, so stainless steel is recommended.
Do these industrial casters require maintenance?
No, the dual precision sealed ball bearings in the UXY Wheel and swivel plate caster bracket are maintenance-free, ensuring smooth, quiet rolling. Regularly inspect and clean to maintain hygiene in washdown settings like food processing or labs.
What are the mounting specs for this plate caster?
The Plate Caster Model K3 has a 3-1/8” x 4-1/8” top plate with a 2-3/8” x 3-3/8” bolt hole spacing (slotted to 1-3/4” x 2-15/16”), using 3/8” bolts, fitting standard carts for light duty industrial casters in sanitary settings.
Is the Plate Caster Model K3 with UXY Wheel NSF-listed for food service?
Yes, this light duty industrial caster is NSF-listed, and the UXY Wheel is assumed NSF-rated, making it ideal for casters and wheels in food service, hospitals, or labs where hygiene and floor protection are critical. Confirm with the supplier for wheel certification.
How do I select the UXY Wheel for swivel plate casters?
Choose a 1.25” wide UXY Wheel with 3”, 4”, or 5” diameter and 3/8” axle, featuring dual precision sealed ball bearings for swivel plate casters like Model K3, ensuring non-marking, ergonomic performance in labs or food processing.
How does this industrial caster compare to nylon casters for sanitary settings?
The Plate Caster Model K3 with UXY Wheel offers quieter rolling and better shock absorption than nylon casters, with similar 350 lbs capacity. Nylon excels in chemical resistance, but this light duty industrial caster prioritizes floor protection and ergonomics in hospitals or food service.
What role does the rigid design play in this plate caster?
