Bearing Pillow Blocks
Bearings are used for the easy movement of a mechanical system. The motion is allowed in only one direction and the main advantage of bearings is reducing friction. So, it ensures long service of the mechanical parts. It has a housing unit to protect the bearings from contamination. Depending on the bearings are used for both light and heavy loads.
The housing of the bearing is used as support for the rotating shaft. The main use of bearing pillow blocks is in mechanical power transmission systems to support their rotating shaft. Its units are housed with mounting surfaces. The block is fitted to the foundation and is inserted into the rotating shaft. The bearings are available in different models and shapes. Cylindrical Roller, Spherical Roller, Tapped Roller, and Metallic Roller are the most common type of bearings available in the market.
The rollers define the type of bearings. The advantage of block bearings is easier to install and offers long-lasting performance. High-quality materials are used to ensure the performance of the bearings. The size of the bearings depends on their application. You have to consider the type of load that has to be carried and the size before selecting the bearings.
The housing for pillow blocks is used with high-capacity spherical roller bearings. The re-lubrication system of bearing is an added advantage.
Types of Block Housing
Mainly two types of housings are available.
Split Bearing Housing – it is made up of two pieces that can be separated. Thesetype of bearings are easier for cleaning and maintaining by lubricating.
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 Materials for Bearing Pillow Blocks
The main purpose of the housing is to protect from contamination and also protect while it is in function. So, good quality materials should have used for the manufacturing of the bearings. The housing ofbearingpillow blocksare made with
Cast Iron – cast iron is a combination of carbon, steel, and iron. These bearings assure long-lasting performance under any condition.
Aluminum – as it has high load carrying capacity and thermal strength, it is used for manufacturing the bearing houses.
Pressed Steel- its carbon steel. This made through pressed process than machined. The pressed steel is less expensive than other materials.
Stainless Steel- it can be used in any extreme condition as it is the capacity to resist corrosion sues to chemicals and the environment.
When you are about to buy a bearing you have to be very careful about the purpose and the materials used for manufacturing the bearings.
