A housing of a bearing supports the bearing units and protects them from other contamination or damage. Normally it is used for light-load applications. The blocks are mounted in a housing and can be bolted for support. The selection of the best housing and bearing model increases the performance of a mechanical system.

Housed bearings are used to support the rotating shaft. Bearing Pillow Blocks are mostly used in mechanical power transmission systems to support their rotating shaft and coupling. Its units are housed with mounting surfaces. The block is mounted to a foundation and a shaft is inserted for rotating the shaft.



The housed bearing units are available in different types of bearings such as Cylindrical rollers, Spherical rollers, Tapped rollers, and Metallic rollers. The type of roller defines the nature of bearing. It works on a pedestal thatsupports the mounted housing and rotating shaft. Its advantage is that it is easier to install without compromising the performance. High-quality materials have been used in the manufacturing of the bearings.The size of the bearings ...
... varies based on their application.

Environment, size, and load have to be considered while selecting blocks.

Pillow block housing can be used with high-capacity spherical roller bearings. It has a re-lubrication facility with grease or oil as a lubricant.



Types of Bearing Blocks Housing

There are two main types of bearing blocks housings are available.

Split Bearing Housing – it is made up of two pieces that can be separated. These kinds of bearing housing are easier for cleaning, lubrication, and replacements.



Solid Bearing Housing –it is made up of a single piece

As there are different kinds of rolling and housings are available, certain combinations of these two give better performance.



Selection of Bearing Pillow Blocks

There are certain criteria in selecting the pillow bearingblock. Some of them are as follows.

Selection of bearing type – selection of load type, shaft size, running speed, misalignment, etc. are making the nearing suitable for its application.


Selection of suitable housing materials


The selection of suitable shaft attachments like a screw, electric lock, single or double set collar, etc. contributes to better performance.


Selection of appropriate housing split or solid type wherever it is necessary to increase the machine performance.


For high load applications choose the suitable materials and type of bearing

The application of bearing pillow blocks are in belt drives connecting in motor and pump, rolling mills, ventilation system, paper machines, and conveyor belt rollers.


There are several options have been available for selecting a bearing. You have to do thorough research for the best housing and materials used for it. With proper selection and maintenance, these bearings can last for many years. Appropriate selection of blocks contribute to better performance.
