The reliefs of ancient Egypt first appeared in the walls and ramps of the pharaoh's tomb. These reliefs record the life and deeds of Pharaoh's life. The reliefs of all murals are elegant in style, beautiful in lines and rich in content. They not only express the various pastimes of the rich, but also describe the production labor of ordinary people, in the process of stripping, cutting, rushing, threshing, and throwing the field. . There is an embossed painting of the shipbuilding 4,500 years ago, as well as the cutting of trees, cutting boards, and the use of flat axe, handcuffs and shovel. It can be seen that saws, axes, awls, etc. have been commonly used. There is a gold smith's embossed embossed embossed to the furnace to increase the temperature of the furnace. There are also works that show the daily work of the carver, the stonemason and the cobbler. There is also a relief showing that a group of people were rushed to the house of Titian like a sheep to check out. When they walked slowly, they were pulled by the guards and pulled their collars to Lira. Many peasant women grow up to offer gifts to Pharaoh, a group of servants, some holding bulls for sacrifice; some are slaughtering. Some reliefs show Pharaoh eating, or working with his wife and the whole family, or hunting, or traveling on the Nile Delta, or walking through the papyrus. The wild cats hidden in the papyrus painted in the tomb of the local governor of Beni Hashan in the Middle Kingdom period are excellent. The murals of the New Kingdom period have a lot of sketching themes, and the fish, the flying birds, the running bisons, etc., are all vivid. Egyptian reliefs are mostly thin reliefs, that is, intaglios with images below the background plane. During the New Kingdom period, such reliefs have developed greatly, and there are many works left over. Many of these paintings and reliefs reflect the life of society, including various labor scenes in agriculture, horticulture, and handicraft workshops, as well as animal husbandry, hunting, rulers' daily life, market, transportation, and so on. Among these carvings, the characters are the most distinctive. The portraits are all positive and dignified, and the representative works like the statue of Zifflin, which reflects the inviolability of Pharaoh. The huge Sphinx is also famous. In addition, such as the official image, the statue of the book, the style is extremely simple. The statues of the Middle Kingdom have been further developed, and some attempts to portray the inner feelings of the characters, such as the statues of Amenem Heit, Xenuselt III, etc. are such works. The wooden statue of the sacrificed person in the 11th Dynasty was also very successful. The art of carving in the New Kingdom period is more mature. During the period of the religious reform in Echnaton, the shackles of art from the influence of tradition made the painting and sculpture develop in the direction of lively realism, breaking the stagnation of the ancient kingdom. The famous Queen of Nefertti is like the best of them. Corresponding to the art of relief and painting is the prosperity of architectural art. At that time, most of the building materials used stone, so many of them have stood up to this day. The Great Pyramid of the Fourth Dynasty was the tallest building in the world before the completion of the 19th century Paris Tower, and was hailed as the wonder of the ancient world. Other buildings such as temples and temples are also very majestic. Completed in the main hall of the Temple of Abyss in Ramses II, with a total area of ​​5,000 square meters, with 134 cylinders, the highest 12 columns in the middle up to 21 meters, each column can accommodate 100 people The size of it can be imagined. In addition, the temples of Luxor, the tomb of Tutankhamun, the tomb of Ramses II, and the palaces of El-Amarna are also majestic. The ancient Egyptian rulers built these huge buildings in order to reflect the supreme power of Pharaoh's theocracy.
The UCF pillow block mounted bearing series has four bolt holes, and a set screw lock is designed for mounting onto bearing surfaces parallel to the shaft axis, such as conveyor belts. This ready-to-mount unit has solid base cast iron housing, chrome steel bearings, and is designed for efficient operation at a wide range of speeds. This one-piece pillow block housing allows for a stationary outer ring and rotating inner ring. Insert bearing maintains the separation between moving parts to reduce rotational friction, and to support radial and axial loads. The bearing is secured to the shaft with set screws to prevent slippage. This mounted bearing is used in food and beverage manufacturing, textile industry and many other industrial manufacturing.
Pillow blocks are usually referred to the housings which have a bearing fitted into them & thus the user need not purchase the bearings separately. Pillow blocks are usually mounted in cleaner environments & generally are meant for lesser loads of general industry. These differ from "plummer blocks" which are bearing housings supplied without any bearings & are usually meant for higher load ratings & corrosive industrial environments. However the terms pillow-block & plummer-block are used interchangeably in certain parts of the world.

However fundamental application of both types is the same which is to primarily mount bearings safely enabling their outer ring to be stationary while allowing rotation of the inner ring. The housing is bolted to a foundation through the holes in the base. Bearing housings are either split type or unsplit type. Split type housings are usually two piece housings where the cap and base can be detached. While certain series are one single piece housings. Various seals are provided to prevent dust and other contaminants from entering the housing. Thus the housing provides a clean environment for the expensive bearings to freely rotate hence increasing their performance and duty cycle.
Bearing housings are usually made of grey cast iron. However various different grades of metals can be used to manufacture the same.
