Wholesale Drive Pulley | Newest Designs from China

      The shaft and hub are connected via a single key, and the web is welded to the cylinder body, forming a single-extended shaft structure. They are suitable for light-load, short-distance, and low-volume conveying scenarios, offering easy installation and cost-effectiveness. Medium-duty rollers have a bearing hole diameter of 120–180mm. The shaft and hub are connected using an expanding sleeve (power lock). They feature moderate structural strength and stable operation, making them ideal for medium-load and medium-to-long distance conveying systems. Heavy-duty rollers have a bearing hole diameter of 200–220mm and also use an expanding sleeve connection. They exhibit high overall strength, rigidity, and strong impact resistance, specifically designed for heavy-load, high-volume, and harsh conditions in coal mines, mines, ports, steel plants, and other industries. All three types of rollers have reasonable structures, reliable connections, and smooth operation, meeting the conveying needs of different industries and loads with long service life and convenient maintenance.
