Conveyor Hanger Bearing Without Plastic Bush

A casting screw conveyor hanger bearing without a plastic bush refers to a specific type of bearing arrangement used in screw conveyors. Screw conveyors are devices used for the movement of bulk materials, typically in industries such as agriculture, food processing, and manufacturing. The hanger bearing is a crucial component that supports the rotating screw shaft within the conveyor. Here’s a description of a casting screw conveyor hanger bearing without a plastic bush:

1. Material and Construction: The hanger bearing is typically made using a casting process, wherein molten metal is poured into a mold to create the desired shape. Common materials for these bearings include cast iron or other metals suitable for the specific application.
2. Lack of Plastic Bushing: Unlike some hanger bearings that incorporate plastic bushings or liners for reduced friction, a casting screw conveyor hanger bearing without a plastic bush relies solely on the metal components for support and rotation.
3. Design for Heavy Loads: This type of hanger bearing is designed to handle heavy loads and provide support to the screw shaft, which is crucial for the efficient movement of materials in the conveyor.
4. Durability and Strength: The absence of a plastic bushing means that the bearing relies on the inherent strength and durability of the metal used in the casting. This design is often chosen for applications where resistance to wear and tear is essential.
5. High Temperatures Resistance: The casting material is selected to withstand the operating temperatures of the screw conveyor system, especially if it involves conveying materials at elevated temperatures.
6. Maintenance and Lubrication: Depending on the design, these bearings may require periodic maintenance, including lubrication, to ensure smooth operation and prevent excessive wear.
7. Precision Machining: The bearing components undergo precision machining to achieve the required tolerances and ensure proper fit and functionality within the conveyor system.
8. Installation: The casting screw conveyor hanger bearing is typically installed at strategic points along the length of the screw conveyor to support and guide the rotating screw shaft.
9. Application Specifics: The design and material selection may vary based on the specific requirements of the screw conveyor application, taking into consideration factors such as material type, conveyor length, and operational conditions.

It’s important to note that while some hanger bearings utilize plastic bushings for reduced friction and improved efficiency, the casting screw conveyor hanger bearing described here opts for a robust all-metal construction, prioritizing strength and durability in heavy-duty applications.
