Hangers are the crucial intermediate support brackets located along the length of a screw conveyor, allowing for the use of multiple screw sections. They come in a variety of styles, each designed to match a particular application's requirements. Hangers are generally recommended for conveying free-flowing bulk materials, as the bulk material must be able to flow smoothly around the hanger. However, they are not suggested for use when conveying abrasive and sluggish bulk materials due to potential operation hindrances. Selecting the appropriate hanger style, material, and maintenance schedule can significantly optimize the performance of your screw conveyor system.

Screw conveyor bearing hangers are manufactured specifically to hold and support the conveyor screws, typically incorporating a bearing that enables the free-spinning of the screw. These hangers are available with or without a lubrication pipe. Hangers that come with a lubrication pipe typically utilize Babbit bearing, bronze bearing, or ball bearings, but other bearing options are available upon request. We offer screw conveyor hanger assemblies for both standard and heavy-duty abrasive applications and for standard as well as flared conveyor trough types.
Hanger bearings, integral components of a screw conveyor, provide a supportive bearing surface for the screw section, especially when multiple screw sections are involved. They are either journal or plain type bearings that are housed within hangers, ensuring an efficient and friction-less operation. Their easy-replaceability is a significant advantage, especially when these bearings become worn out. Furthermore, hanger bearings come in a vast range of materials, each one tailored to suit specific applications, thus ensuring versatility and adaptability in various industrial settings.
The longevity of a hanger bearing is primarily determined by the material with which it's made, and the maintenance it receives. As stated earlier, wood, hard iron, various plastics, and bronze are commonly used materials. Each material comes with its pros and cons. For instance, while wood and hard iron are popular due to their easy sourcing, they may not necessarily be the best fit for all applications.
The hanger bearing you choose should align with the specific needs of your screw conveyor. For instance, considering the type of materials you plan to move, the frequency of use, and the amount of load the conveyor will carry could help you decide on the suitable material. Always remember to make regular checks and maintenance checks on your hanger bearings and replace them when necessary, to ensure the smooth operation of your screw conveyor. Remember, selecting the right hanger bearing material is fundamental to achieving optimal screw conveyor performance.
