5" Polyurethane Stem Caster, 330 lbs Load, Plate Mount for Hand Trucks, Pkg Qty 8

Overview

This heavy-duty caster assembly is engineered for rigorous material handling environments, specifically designed to enhance the mobility and load-bearing capabilities of industrial hand trucks and transport equipment. Each unit features a robust 5-inch polyurethane wheel that balances high weight tolerance with superior floor protection. The construction prioritizes durability and smooth operation, making it an essential component for facilities requiring reliable movement of heavy loads across varied surface conditions. Sold in packages of eight, these casters provide a cost-effective solution for fleet maintenance or new equipment fabrication.

Key Features

High-load polyurethane wheel construction supports up to 330 lbs per caster Non-marking tread protects sensitive warehouse and factory flooring Low rolling resistance ensures effortless maneuverability under full load Rigid plate mount design provides stable and secure attachment points Resilient material withstands impact, debris, and continuous industrial use Smooth rotation reduces operator fatigue during prolonged pushing or pulling

Specifications

Load Capacity: 330 lbs Wheel Diameter: 4.9 inches Overall Dimensions: 5.9 x 2.4 inches Wheel Material: Polyurethane Mounting Type: Plate Mount Package Quantity: 8 units Recommended Use: Heavy-duty hand trucks and industrial carts

Applications

Warehouse logistics and distribution center operations Manufacturing assembly line material transport Hospitality industry luggage and linen cart maintenance Healthcare facility equipment relocation Retail stockroom inventory management Food service kitchen utility cart upgrades These casters are specifically optimized for environments where floor integrity is as critical as load capacity. The polyurethane formulation offers a unique combination of hardness for load support and elasticity for shock absorption, preventing damage to both the equipment frame and the underlying floor surface. Unlike softer rubber compounds that may deform under heavy static loads, this material maintains its shape while providing a quieter operation compared to nylon or phenolic alternatives. The plate mount configuration allows for straightforward installation onto existing metal frameworks using standard fasteners, ensuring a rigid connection that minimizes wobble during transit. With an overall height profile that fits standard hand truck geometries, these units serve as direct replacements for worn components or as upgrades for lighter-duty original equipment. The inclusion of eight units per package facilitates complete overhauls of four-wheeled carts with spares available, or the equipping of multiple two-wheeled hand trucks simultaneously. This product delivers consistent performance in temperature-controlled indoor settings as well as sheltered outdoor loading docks, provided the surfaces are free of extreme chemical contaminants that could degrade polyurethane over extended exposure periods.
