Different types of bearing play a crucial role in performing various motions. All types of machines big or small make use of these bearings for their efficient working. One such type of bearing having an important role in rotational motion includes the bearing pillow block.

Different types of motions or movements are made possible by using the different types of bearings. These bearings make the motions frictionless and noiseless thus making the motions like rotational, linear, circular, easy, and convenient.

Understanding the bearing pillow block:

The bearing pillow block consists of two parts that support the shaft for rotation in different directions. The outer housing part is attached to the object that needs to be rotated. This house part has the hole, slot, or cavity that allows insertion of the shaft that makes the rotation possible. The second part consists of the bearing that accommodates the shaft in place. These two parts together allow in making the rotational motion.

Selection of the bearing pillow block:

Selection of the wrong size or dimension can lead to accidents or can cause damage. The different parameters that need consideration while selecting the best pillow block bearing include:

The material used: Different types of material are used for the housing and the bearing. Each type of material has its strength that defines the load-carrying capacity of the bearing. These different materials include aluminium, cast iron, polymer, plastic, alloy, etc. One must select the material after understanding the load that has to be rotated.

Diameter of shaft: The housing part of the bearing has the hole or bore that houses the shaft. The selected shaft should be of an optimum size to fit into this bore. A shaft diameter smaller or bigger than the bore size can lead to slipping or dislocation.

Height of shaft: The height of the shaft selected depends on the distance between the center of the shaft and the base of the block bearing. Optimum height is essential for proper rotation.

Speed of the rotation: Speed of the rotation decides the selection of the bearing. Each bearing has its capacity and cannot be used for the speed beyond the set speed. The maximum allowable speed of each bearing should be considered while making the selection.

Load-carrying capacity: Each bearing has a specific load-carrying capacity. Based on the load that needs to be rotated, the bearing should be selected.

All these parameters should be considered while selecting the best suitable bearing for the proper working.

These bearings are available in different sizes and dimensions. Selection of proper dimension of bearing pillow block is important for the efficient working of the machine part.
