Methods of Lubrication for Bearings

Lubrication of components plays a vital role in the systematic functioning of the each part of the bearings. Hence, the mechanism that accommodates the lubrication of these components should also be given equal priority. The different types of lubrication system available for lubrication of bearings are:

  1. Ring lubrication
  2. Wick lubrication
  3. Splash lubrication
  4. Grease lubrication
  5. Bath Lubrication
  6. Air Oil Mist Lubrication
  7. Jet Lubrication
  8. Pulsed Air Oil Lubrication

Ring Lubrication System

The method of ring lubrication involves a ring hanging from down the rotating shaft. The bottom portion of the ring is immersed in the oil container. When the shaft starts rotating, the ring also rotates. While the ring rotates, it carries a small amount of oil and the oil is spread into the bearing and the shaft.

Wick Lubrication System

Wick lubrication is a method in which the wick along with a flexible thin piece of metal is used. A container having oil is placed above the bearing. The wick connects the container and the part to be lubricated. This lubrication enables the oil to flow from the container to the required place.

Splash Lubrication System

The rotating part of the machine itself is made to be immersed in the oil container. When the part starts rotating, the oil is splashed and the moving parts are lubricated. Bearings are generally lubricated by this method. Little spoons are attached to the rotating parts to get more quantity of oil to the part to be lubricated.

GreaseLubrication System

Grease lubrication is done with the help of grease guns. Another way of doing it simply is to fill a container with grease and the container is connected to the parts to be lubricated by means of a small tube. When a screw is screwed into the container, a good amount of grease is taken to the required place.

Bath Lubrication System

The bath system of lubrication is the mostly commonly applied system for the lubrication of bearings. Here the bearing is dipped in the oil to a certain level. The level of the oil is maintained constant thus providing copious supply of oil to the bearing.

Air Oil Mist Lubrication System

In this type of system, oil mixed with air in a certain proportion is sprayed into the bearing at high pressure. This is the excellent system available for bearings operation at high speeds of above 3000 rpm and operating under very light loads. This system provides excellent cooling for the bearings.

Jet Lubrication System

Oil is force fed into the bearing at high pressure and quantity by using an external pump. The oil is specifically directed towards the bearing rolling elements by means of a pipe. This lubrication system in used in cases where the bearings is subjected to very heavy loads, high speed and high temperature. This system also provided effective cooling for high temperature applications of bearings.

Pulsed Air Oil Lubrication System

This system is quite similar to the Air Oil Mist Lubrication system. Here the air and oil are supplied to the bearing in pre-defined quantity pulses to the bearing. The ratio of air to oil mixture in this system is quite high.
