Metallic Bearings

Metallic Bearings is a small mechanical component which is made for the primary purpose of reducing frictional force and providing support to radial and axial loads. The bearings in a way are very important part of a mechanical system where it provides frictionless rotational movement of a whole system. It is a component in which parts are isolated by a ring of freely rotating balls for the purpose of reducing friction.

The metallic bearings are made of different types of metals, such as chrome steel, stainless steel, carbon steel bearings, etc. These bearings are made keeping in mind different application requirements. Different types of steel bearings are highly resistant to corrosion and rusting. Proper lubrication, however, is compulsory to keep the bearings in perfect order.

Types of Metallic Bearings

Metallic bearings are manufactured in different types of metal. Some of the types of metallic bearings are as given below|:

Carbon Steel Bearings – this is also referred to as commercial grade bearings contains carbon of up to 2.1%. The significant carbon content in the bearing makes it much stronger. It is preferred for its hardness and for cheaper prices. Carbon steel bearings are generally used in locks, roller skates, bikes, rolling draws and shopping carts.

Chrome Steel Bearings – Chrome steel bearings is an important type of metallic bearing that is known for high hardness level and less noise. It has a high load capacity and low decibel design. It requires regular lubrication for optimum functioning. However, it doesn’t contain much quantity of chromium as the name may suggest. Chrome steel bearings are extensively used in food processing machines, vibrating motor systems and linear motion components.

Stainless Steel Bearings – stainless steel bearing contains lower carbon percentage than carbon steel bearing and higher chromium content compared to chrome steel bearing. This type of metallic is highly resistant to corrosion and rusting as well as chemicals. It is softer and flexible to temperature than other bearing types. Although it comes with several advantages, a few unpleasant aspects about stainless steel bearings are that it requires more lubrication and higher costs because of the heavier composition. It main uses are in food processing, instrumentation, metal plating, and chemical prone and high humidity areas.

Uses of Metallic Bearings

The most common used of metallic bearings are in:

• Wind Turbines
• Pumps
