Skid Conveyor Rollers

Skid conveyor rollers feature a steel core and high-strength polyurethane overlay, achieving a hardness of A85–A95 and a thickness of 8–25mm. Each wheel has a load capacity of 500kg to 2 t. These wheels offer high load capacity, wear resistance, noise reduction, and corrosion resistance, making them widely used in automotive manufacturing, heavy industrial assembly lines, and paint shops.

What is a skid conveyor?

A skid conveyor system is a computer-controlled material handling system that utilizes specialized tracks and wheel trains to provide automated, flexible, and precise transport of heavy goods.

Functions of the skid system PU wheel

• Supporting heavy loads – Carrying loads

• Directing – Precise guidance

• Effort saving – Reducing friction

Structural features of skid conveyor wheels

• Wheel structure

The inner wheel core is typically made of steel or cast iron to ensure overall strength.

The outer wheel ring is coated with a highly wear-resistant polyurethane layer for reduced vibration, noise, and protection.

• Bearing Design

Equipped with high-precision deep groove ball bearings or tapered roller bearings, the bearings maintain smooth operation under high loads and continuous operation.

• Mounting Method

Bolt fixing or bearing seat mounting is commonly used, making replacement and maintenance easy.

Polyurethane hardness

• Commonly used Shore A85-A95 or Shore D50-D70 grades, depending on the operating conditions.

• High hardness (A95/D70) → More wear-resistant, suitable for high loads.

• Medium hardness (A85) → Balanced vibration reduction and noise control, suitable for welding and coating lines.

Polyurethane thickness

• Common overmolding thicknesses range from 8mm to 25mm.

• Thicker thickness → Greater elasticity and vibration absorption.

Load capacity

• A single skid pulley can carry 500kg to 2 tons.

• Varies depending on wheel diameter, polyurethane hardness, thickness, and core material.

• Customizable to suit the overall load of the skid conveyor line.

Advantages

• High Load Capacity → The steel core combined with high-strength polyurethane can withstand the weight of large components such as automobile bodies for extended periods.

• Wear-Resistant & Long Life → The polyurethane coating reduces metal friction and extends service life.

• Noise Reduction & Protection → The polyurethane layer absorbs shock and vibration, reduces noise, and protects the workpiece surface.

• Adaptable to Complex Environments → Oil-resistant, corrosion-resistant, and high-temperature resistant (customizable up to 120°C).

• Easy Maintenance → Modular design allows for easy installation and replacement.

Applications

• Automotive Manufacturing

Widely used in skid conveyor systems for welding lines, final assembly lines, and painting lines.

Carrying automobile bodies and complete assemblies.

• Heavy Machinery & Engineering Equipment

Workpiece transport in large equipment and construction machinery production lines.

• Painting & Paint Shops

The polyurethane coating is corrosion-resistant and adaptable to chemicals and high-temperature environments.

• Logistics & Warehousing

For automated handling of pallets, steel structures, and large components.

• Ship & Rail Transit Manufacturing

Handling and assembly lines for large vehicle bodies and ship hull components.
