All products have passed actual mining condition tests, with uniformly qualified materials and performance. They only differ slightly in load-bearing capacity and dimensions, allowing for precise matching based on your equipment’s load requirements, installation space, and operating scenarios—no need to worry about quality issues! If you’re unsure about the suitable dimensions for your equipment, please provide the equipment model or parameters of your existing wheel sets, and we will assist you with a more accurate recommendation!
We supply heavy-duty wheels of all sizes for various models of shield tunneling machines, including railway construction, subway engineering, highway engineering, mining engineering, and various pipeline engineering. The walking wheels of the shield tunneling machine are made of NDI polyurethane elastomer as the tread material to ensure optimal load-bearing and tear resistance performance, while ensuring no delamination failure. We provide full-size press fit wheels and assembly services for shield machine customers. Common specifications range from 300mm to 560mm in diameter. The NDIthane walking wheel specially designed for shield tunneling machines we produce adopts a press fit assembly form, mainly consisting of two wheel structure, three wheel structure, and four wheel structure, achieving a minimum load capacity of 6000 kilograms to 30000 kilograms per unit
The friction driven wheels of our monorail crane are made of NDIthane 95 material, which has the best wear resistance and load-bearing capacity. At the same time, the friction coefficient exceeds 0.5, ensuring driving force and braking effect. The service life exceeds 2000 hours, with low internal heat generation and long service life. NDIthane polyurethane endows the driving wheel with greater load-bearing capacity and better wear resistance. Under strong clamping force, it generates low heat, maintains the mechanical strength of the material itself, is durable and reliable, and avoids the problem of degradation or delamination caused by the heating of the tread when the friction driving wheel moves under a tightening force of 8-11MPa.
Mining casters are key components of mining transportation equipment that require special requirements such as high strength, wear resistance, and explosion resistance. Currently, polyurethane is the most commonly used material. Polyurethane casters are wear-resistant and corrosion-resistant, suitable for wet underground environments, and have good load-bearing capacity NDI polyurethane heavy-duty casters are composed of heavy-duty metal brackets, high load bearings, steering ball bearings, and NDI polyurethane tread materials. They adopt a dual bearing structure of tapered roller bearings and ball bearings, which disperses the load gravity and provides flexible steering, increases the contact area of the load, reduces the impact force of the load, and minimizes the force required to change direction and the lateral stress on the ground facing the tire. They operate more flexibly and enhance the service life of the tire.
Yalide Technology focuses on providing customers with one-stop system solutions for roller/shaft/wheel products.
