Polyurethane Drive Wheels for Stacker Crane Boxes AS/RS

19 Mar 2026

Stacker crane wheels for boxes are specialized components designed for automated storage and retrieval systems (AS/RS),requiring high load capacity, durability, and low maintenance.

In automated warehousing, the efficiency and durability of material handling equipment depend on high-quality components. Polyurethane drive wheels are engineered specifically for stacker cranes in Automated Storage and Retrieval Systems (AS/RS) handling both pallets and boxes, providing the necessary traction and load-bearing capacity for modern logistics.

Key Advantages of Polyurethane Drive Wheels

Polyurethane (PU) is the preferred material for AS/RS drive wheels due to its superior mechanical properties compared to traditional rubber or metal:

1. High Load-Bearing Capacity: Engineered to support the heavy weight of stacker cranes and full-load pallets/boxes without deformation.

2. Superior Traction & Grip: High friction coefficients ensure precise acceleration and braking, which is critical for pinpoint positioning in narrow aisles.

3. Operational Durability: Resistant to abrasion and flat-spotting, even under repetitive high-cycle operations, reducing downtime.

4. Floor Protection: Unlike steel wheels, polyurethane protects warehouse floors and guide rails from excessive wear while maintaining quiet operation.

Difference Between Drive Wheels and Guide Wheels for Stacker Cranes

Understanding the distinct roles of these two components is essential for optimizing AS/RS maintenance and performance:

Feature	Drive Wheels (Propulsion)	Guide Wheels (Alignment)
Primary Function	Responsible for horizontal travel and traction.	Maintain crane alignment and absorb lateral forces.
Installation	Mounted on the drive motor/chassis base.	Mounted on the sides of the mast or guide rail interface.
Load Focus	Vertical load and torque transmission.	Lateral (side-to-side) impact and stability.
Key Requirement	High friction and compression resistance.	Low rolling resistance and impact absorption.

Technical Tip: While drive wheels power the movement, [Guide Wheels for Stacker Cranes] ensure the system stays perfectly on track. For maximum longevity, we recommend using NDI-based polyurethane (Vulkollan equivalent) for both types to ensure consistent hydrolysis resistance

Optimized for AS/RS Storage Density

The load-bearing strength of our polyurethane wheels directly impacts your warehouse's storage density. By supporting heavier payloads without compromising structural integrity, these wheels allow stacker cranes to handle denser box stacks and larger industrial pallets, maximizing vertical space utilization.

Conclusion

Polyurethane drive wheels are a foundational element of high-performance automated warehouse systems. By ensuring high load capacity and reliable traction, they enable warehouses to achieve higher efficiency and lower maintenance costs. As the demand for automated logistics grows, selecting the right wheel specification becomes critical for supply chain automation.
