Lagergehäusen

Lagergehäuse (plural Lagergehäusen) are rigid enclosures that house a bearing and provide mounting and alignment support for rotating shafts. They protect bearings from contaminants, help distribute loads, and offer a mounting interface to attach the assembly to a machine frame. Many designs include lubrication management features and seal arrangements to retain lubricant and exclude dirt.

They are typically made from cast iron, ductile iron, steel, or aluminum and come in several configurations, including pillow block bearing housings (with an integrated base and mounting holes) and flanged bearing housings (with a mounting flange for surface attachment).

Inside, the bearing sits in a precisely bored bore, typically with a press fit or close running fit. Housings may include seals, lubrication grooves, grease fittings, and drain plugs. Some are designed for sealed bearings, while others provide channels for oil or grease lubrication.

Applications span conveyors, machine tools, pumps, and other industrial equipment. Maintenance involves checking alignment and bearing condition, replacing worn bearings, and following lubrication schedules. Key selection criteria include bore size, overall dimensions, load rating, mount type, material, and environmental protection (dust and moisture resistance).
