Bearing bearing housings & units flange housing

A bearing housing assembly is a structural unit that includes a bearing and its housing. It serves to securely connect the bearing to other parts of the mechanism, as well as to protect the bearing from external influences such as dust, dirt, moisture, and to maintain the correct position of the bearing during operation.

Main functions of the bearing housing assembly

- mechanical support of the bearing (the housing holds the bearing in the correct position and transfers the load to other parts of the structure);

- protection of the bearing (the housing protects the bearing from dust, dirt, moisture and other harmful environmental factors, which helps to extend the bearing's service life);

- bearing lubrication (many housings have built-in bearing lubrication channels to reduce friction and heat during operation);

- load distribution (the housing assembly helps to distribute the load evenly, which allows the bearing to operate stably and with minimal wear).

Types of bearing housings

Bearing housings can be of different designs depending on the type of bearing and the specifications of the mechanism.

- housing assemblies for radial bearings (capable of bearing loads only in the radial direction (transverse to the axis of rotation), the housing of such assemblies is usually made of metal or plastic and has various structural elements to ensure reliable bearing fixation);

- housing assemblies for angular contact bearings (can withstand both radial and axial loads (rotational loads), the housings have special designs to ensure proper bearing orientation and load distribution);

- housing assemblies for spherical bearings (can compensate for slight misalignment of shafts or parts of the structure, have special housings that allow maintaining the correct bearing orientation even with slight deformation);

- housing assemblies for bearings with seals (designs that include seals to prevent contamination and moisture from entering the bearing, used in conditions where bearings may be exposed to aggressive media such as water or dust);

- housing assemblies for bearings with active lubrication (assemblies have a built-in lubrication system that supplies lubricant directly to the bearing, which helps to improve performance and extend bearing life).

Structural elements of bearing housing assemblies

- housing (made of various materials such as cast iron, steel, aluminum or plastic, depending on the operating conditions, and has holes for attachment to other parts of the mechanism);
- seals (many housing assemblies have sealing elements (rubber cuffs or metal rims) to prevent lubricant leakage and contamination);
- fasteners (bolts, nuts, studs or other fasteners are used to fix the housing in place; fasteners can be standard or special, depending on the design requirements);
- lubrication systems (the enclosure may have channels for supplying oil or built-in oil cartridges; sometimes centralized oil supply systems or special oil tanks are used).

Materials for the manufacture of bearing housing assemblies

- cast iron (has a high ability to absorb vibrations and withstands loads well; usually used for heavy and not very fast rotating mechanisms);

- steel (provides high strength and the ability to withstand heavy loads at high rotational speeds; used in conditions where high accuracy and reliability are required);

- aluminum (lightweight and corrosion-resistant material, often used for compact mechanisms);

- plastic (in some cases, bearing housings can be made of plastic to reduce weight and costs).

Advantages of bearing housing assemblies

- protection against contamination (housings help to prevent dust, dirt and water from entering the bearings);

- ease of installation and dismantling (housing assemblies facilitate the installation and replacement of bearings, reducing maintenance time);

- strength and reliability (housings allow bearings to operate under high loads and temperatures, extending their service life).

The right choice and design of the bearing housing assembly can significantly increase the efficiency and durability of technical systems.
