Unpowered rollers are a type of efficient conveying equipment driven by external force or gravity, and are widely used in logistics, packaging, production lines and other scenarios. Made of high-quality steel, stainless steel or plastic, they are wear-resistant, corrosion-resistant, and have strong load-bearing capacity. They have a simple structure, do not require electricity, are easy to install and maintain, and can be flexibly combined into straight, curved or inclined conveying systems. They are suitable for short-distance transmission of boxes, pallets and other items, effectively reducing manual handling costs and improving work efficiency. They provide a variety of specifications (roller diameter, length, spacing) and surface treatments (rubber coating, galvanizing, etc.) to meet the needs of different industries, and are economical and practical conveying solutions.
