Dual Layer Plastic Skate Wheels are a common and highly effective component in gravity flow storage and handling systems. They consist of a wheel with two distinct layers of plastic co-molded together to create a superior performance profile compared to single-material wheels. These wheels are mounted in a staggered pattern on axles within a frame to create a "skatewheel conveyor," allowing items to be moved with minimal force.
The "Dual Layer" design is the key to their performance, typically combining a rigid core with a softer, functional tread.
Inner Core (Hub): This is typically made from a rigid, high-strength plastic like polypropylene (PP) or nylon. This core provides the structural integrity, ensuring the wheel can bear the load without deforming and that it rotates smoothly on the axle or bearing.
Outer Layer (Tread): This is the functional contact surface, usually made from a softer, high-friction plastic like thermoplastic polyurethane (TPU) or polyethylene (PE). This softer layer provides grip and cushioning.
Low Friction & Easy Rolling: The wheel design, combined with low-friction bearings (often simple bushings or ball bearings), allows loads to be moved with very little pushing force, maximizing the effect of gravity.
Excellent Traction: The softer outer layer provides a higher coefficient of friction than a hard plastic, preventing slippage and ensuring better control of packages, especially during accumulation or minor impacts.
Shock and Vibration Absorption: The softer outer tread acts as a cushion, dampening vibrations and absorbing minor shocks from uneven package bottoms or small gaps between conveyors. This helps protect both the product and the conveyor structure.
Reduced Noise: The plastic construction and dampening effect of the outer layer result in a much quieter operation compared to all-metal roller conveyors, contributing to a better work environment.
Non-Marking and Clean: Plastic wheels will not mark, scratch, or stain the bottoms of cartons, plastic totes, or other finished goods, making them ideal for packaging and final product handling.
Long Service Life: The combination of a rigid core that resists deformation and a tough outer layer that resists wear makes these wheels very durable under constant use.
Corrosion Resistance: Being entirely plastic (and sometimes with stainless steel bearings), they are impervious to rust and corrosion. This makes them suitable for damp environments, cold storage, and wash-down applications (if specified with appropriate bearings).
Low Maintenance: They require no lubrication and are easy to clean. Individual wheels can be popped out and replaced quickly if they ever become damaged.

Dual Layer Skate Wheels are the go-to solution for a wide range of light to medium-duty applications where easy, low-cost manual movement is required.
Packing and Sortation Lines: Used in the final stages of order fulfillment where packed cartons are manually pushed to sorting lanes or shipping areas.
Loading Docks: Creating short, portable sections to assist in moving packages from pallets onto conveyor systems or into trucks.
Accumulation: Gravity flow racks (a type of high-density storage) use skatewheel conveyors to allow cartons to flow from the loading end to the picking face using only gravity.
Assembly Line Transfer: Used between workstations to allow operators to easily slide work-in-progress items along the line.
Buffering and Staging: Providing a temporary holding area for components or finished products before the next process.
Baggage Handling: Commonly used in manual baggage sorting areas and for making up baggage carts, as they are gentle on luggage and easy to push.
Stocking and Merchandising: Portable skatewheel sections are used by employees to move products from the backroom to the sales floor efficiently.
Checkout Lines: As a extension for moving large or heavy items at the checkout.
Case Handling: Moving cases of bottled or canned goods in non-production areas. Their corrosion resistance is a key benefit here.
Dual Layer Plastic Skate Wheels are an exceptionally cost-effective and efficient solution for manually handling a high volume of uniform, flat-bottomed items. Their dual-layer construction provides the perfect balance of structural strength and functional grip, ensuring long life, smooth operation, and product protection. They are the ideal choice for creating flexible, low-maintenance gravity conveyor systems in logistics, manufacturing, and retail environments.
