4 / 5 / 6 Inch Medium Duty Swivel Polyurethane Caster Wheels with Side Brake – 120-180 kg Load Capacity Plate Casters

High-Quality Polyurethane Wheel
The caster wheel is made of premium polyurethane (PU), offering excellent wear resistance, elasticity, and long-term durability. PU wheels roll smoothly while protecting floors from scratches.

Swivel Top Plate Design
The swivel plate structure allows 360-degree rotation, enabling flexible movement and easy handling of carts and equipment.

Side Brake Mechanism
Equipped with a side brake that can quickly lock the wheel, providing reliable stopping power and improving safety during operation.

Double Ball Bearing System
Precision double ball bearings reduce rolling resistance and ensure smooth, stable movement even under medium-duty loads.

Strong Steel Bracket
The steel bracket with zinc-plated surface treatment provides excellent corrosion resistance and structural strength for industrial environments.

This medium-duty caster wheel is designed to provide stable mobility for equipment, carts, and storage systems. The polyurethane tread absorbs shock and reduces noise during movement, while the side brake allows equipment to remain securely positioned when needed.

Caster wheels in the 4-6 inch range with PU material and ball bearings typically support loads around 120–200 kg depending on wheel size, making them suitable for medium-duty industrial applications.

These polyurethane caster wheels are widely used in:

• Tool carts and trolleys
• Warehouse logistics equipment
• Workbenches
• Industrial machines
• Storage racks
• Material handling carts

PU caster wheels are commonly used in workshops and factories because they are wear-resistant, quiet, and resistant to oil and chemicals.
