Description
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.
