Hanger bearings are bearings
contained in a round housing, designed to provide adjustable support in high vibration conditions, especially screw conveyor applications. The housing usually features a threaded boss for vertical mounting, or a fixed swivel for proper alignment with the shaft. Housing units can be single-piece, which are non separable, or split-piece housings that are bolted together for ease of maintenance or bearing replacement. This unique design is suitable for a variety of applications such as agricultural equipment, heavy industry, automotive assemblies, marine driveshaft assemblies, and aircraft assemblies.Locking types for the housing units include setscrew and eccentric locking collar; a locking mechanism is essential to prevent loose bearings and excessive movement or misalignment. Bearing inserts are replaceable and include roller bearings and plain bearings. Plain hanger bearings feature continuous surface contact between raceways, while roller bearings feature rolling elements between the raceways to minimize friction. Many materials for bearing inserts
are available as well, such as steel or ceramic. Most bearings require continuous lubrication
, which is essential to the operating life and performance, unless the bearing is self-lubricating. Ceramic bearing inserts normally require no lubrication, and can provide extended operating life, reduced noise, and reduced friction. Some bearings may include felt seals to protect the lubricant and bearing from dirt and dust, improving operating life.
