4" Polyurethane Stem Caster, Chrome Plated Steel, 286 lbs Load, Pkg Qty 6

Overview

This heavy-duty stem caster is engineered for demanding industrial environments where reliable mobility and floor protection are paramount. Featuring a 4-inch polyurethane wheel mounted on a corrosion-resistant chrome-plated steel fork, this unit delivers exceptional performance in material handling applications. The design prioritizes quiet operation and smooth rolling efficiency, even when traversing uneven surfaces or debris-laden floors. With a robust load capacity of 286 lbs per caster, it provides the stability required for transporting heavy machinery, assembly line carts, and large storage racks. The threaded stem installation method ensures a secure fit that prevents wobbling or detachment during high-speed maneuvers or sudden stops.

Key Features

Specifications

Load Capacity: 286 lbs per unit Wheel Diameter: 4 inches Overall Mounting Height: 5.7 inches Stem Type: Threaded M12 with 25mm length Fork Material: Chrome Plated Steel Wheel Material: High-Density Polyurethane Bearing Type: Precision Ball Bearing Package Quantity: 6 units per pack

Applications

Ideal for pharmaceutical and food processing equipment requiring sanitary, non-marking wheels Suitable for automotive assembly lines transporting heavy components Perfect for hospital beds, laboratory carts, and medical imaging devices Effective in warehouse logistics for order picking carts and portable shelving Recommended for audio-visual equipment stands and stage lighting rigs Used in cleanroom environments where particulate generation must be minimized The combination of a durable metal chassis and a soft-touch polymer wheel makes this caster a versatile solution across multiple sectors. The 5.7-inch overall height provides adequate ground clearance while maintaining a low center of gravity for enhanced safety. Unlike rubber or nylon alternatives, the specific polyurethane compound used here balances hardness for load-bearing with enough give to absorb impacts, extending the lifespan of both the caster and the floor surface. The M12 threaded stem is designed to screw directly into pre-tapped holes, eliminating the need for additional mounting plates or complex hardware. This streamlined installation process reduces downtime during equipment upgrades or replacements. Whether deployed in a humid washdown area or a dry manufacturing floor, the chrome plating acts as a formidable barrier against environmental degradation, ensuring long-term operational reliability without frequent maintenance intervals.
