The Wrights Dowson Group is a trusted supplier of bulk handling equipment and accessories in the UK. We provide long-term, efficient hanger bearing solutions for screw conveyors and bucket conveyors that need to operate even in harsh and abrasive environments.
Hanger Bearings are used as rotational bearings in drive and screw conveyor shafts. They are available in various materials, suited to different applications. Some are self-lubricating, whereas others can cause difficulties through the frequent need for maintenance.
Ensure your operation moves as smoothly as possible and doesn’t suffer frequent interruption.
Here are some things to consider.
Hanger bearings frequently come with two types of constructions. They can consist of a single or two pieces, which is also called a split construction. Single-piece housings can’t be disassembled, whereas split housing can be taken apart. This allows them to be replaced or maintained more easily. The specifications of the bearings, such as their size, depending on the shaft’s diameter.
The Right Material
Hanger Bearings are available in a variety of materials. Common materials include:
- Cast iron
- Plastics and thermoplastics
Bronze hanger bearings can be impregnated with oil for self-lubrication. For more abrasive materials such as slurries, grains and chemicals, wood hanger bearings can be the ideal material.
However, one of the best general-use materials is ceramics, which comes with an extended bearing life and is significantly more quiet in most applications. Ceramic bearings can also apply to CEMA and FDA standards, making them suitable for the meat and poultry or dairy industries in which hygiene is of vital importance.
Ceramic often outlasts other materials. With the Wrights Dowson Group, ceramic split housing hanger bearings are available off the shelf to be ordered today.
Types of Hanger Bearings
Finally, you need to choose between two types of hanger bearings: Plain or rolling element. Plain bearings have continuous contact with the inner and outer races. Rolling hanger bearings have rolling elements placed between the outer and inner races, reducing friction. To minimise wear and tear, this is where frequent lubrication becomes essential. This can extend the life-cycle of a hanger bearing and requires regular maintenance. You will need to lubricate the bearings and clean them.
Ceramic Z bearings can extend the lifespan of your hanger bearings without the need for frequent maintenance.
