Rubber disc return rollers are a type of conveyor roller commonly used in belt conveyor systems. They are designed to aid in the return of conveyor belts to their correct alignment and prevent damage to the belt.
The specifications of rubber disc return rollers may vary depending on the specific application and the manufacturer. However, some common specifications include:
1. Roller diameter: Rubber disc return rollers come in different sizes depending on the width of the conveyor belt. The most common sizes are 89mm, 102mm, 114mm, 127mm, 152mm, and 178mm.
2. Shaft diameter: The shaft diameter of the rubber disc return roller is typically smaller than the roller diameter. Typical shaft diameters range from 20mm to 40mm.
3. Bearing type: The bearings used in rubber disc return rollers are typically sealed, which provides protection against dust and other contaminants.
4. Rubber disk thickness: The thickness of the rubber disk can also vary and is often determined by the weight of the material being transported on the conveyor belt.
5. Load capacity: The load capacity of the rubber disc return roller depends on the diameter, wall thickness, and bearing size.
6. Material: The rubber disk of the roller is usually made of high-quality natural rubber, which has good resistance to wear and tear.
7. Surface treatment: The surface of the roller can be treated with different coatings to improve its performance, such as galvanized or powder-coated finishes.
Overall, the selection of rubber disc return rollers depends on the specific requirements of the conveyor system and the application. It is essential to choose high-quality rollers that can withstand the demands of the application and provide reliable performance over time.
