Types of Guide Pulleys
1. ROTAFRIX® Guide Pulleys
ROTAFRIX® guide pulleys, manufactured by Continental, are designed for durability and high performance in demanding environments, such as hoisting systems in mines. Made from solid rubber, these pulleys feature a special hard elastomer base layer and are available in two abrasion-resistant compounds. Their simple construction ensures low noise and maintenance-free operation, making them ideal for high-speed applications.
2. Shimano Jockey Wheels
Shimano jockey wheels, commonly found in bicycle rear derailleurs, serve as guide and tension pulleys. They are crucial for ensuring smooth gear shifting and can affect the overall performance of the bike if worn out. Each jockey wheel is marked for identification, with the top being the guide pulley (G) and the bottom being the tension pulley (T).
3. High-Speed Pulleys
Cemanco offers a variety of balanced high-speed guide pulleys, which are crucial for applications requiring precision and stability. These pulleys are available in standard sizes and can be customized to fit specific groove configurations. Their design focuses on minimizing vibration and ensuring consistent performance at high speeds.
4. Standard Pulleys
Standard guide pulleys can be found across various industries and are typically made from a range of materials. These pulleys are often designed for general use in production processes. A key feature of many standard pulleys is their ability to be refurbished, allowing businesses to save costs while maintaining high operational efficiency.
5. Guide Rollers
Guide rollers are specialized pulleys used for spooling wire or fiber. These components are often made from aluminum or plastic and are designed for high precision and smooth operation. Their application is critical in industries where material handling needs to be efficient and reliable.
