What are bearings made of?

Bearings are key components in mechanisms that ensure smooth rotation and load transfer. They are made of materials with high strength and wear resistance.

The best place to buy this product is bearing shop. In such companies, you can find the most diverse instrument at affordable prices.

Main characteristics

The following raw materials are used for the manufacture of bearings:

1. Steel. The most common material. It is characterized by high strength, hardness and resistance to wear. As a rule, hardened carbon steel is used: chrome or stainless steel. The first variant is characterized by high hardness and resistance to corrosion. Stainless steel provides additional protection against moisture.
2. Ceramics. They have a low coefficient of thermal expansion. It has high resistance to the effects of water. Products from this material are used in chemically aggressive environments. Aluminum oxide, nitride and silicon carbide are usually used as raw materials.
3. Polymers. Teflon, polyamide and polyethylene are used as manufacturing materials. It has good antifriction ability and self-lubricating properties. Polymer products are light and low-noise. No lubrication required. Such bearings are resistant to corrosion and chemical influences. They are often used in mechanisms used in the food industry.

Titanium and bronze are also used as raw materials. They are used to solve special problems. Titanium bearings are durable and resistant to moisture. Widespread in the aviation and space industries. Bronze bearings provide wear resistance and are suitable for high-intensity loads. Used in marine installations.

Purchase of bearings

The choice of bearings must be approached very carefully. Many details need to be taken into account. It is most profitable to buy bearings in online stores. Such companies offer the most favorable conditions for the purchase of this product and other tools.

The assortment of online stores includes many types of bearings. At the same time, their cost is lower than in ordinary retail outlets. Online stores have a more loyal pricing policy. This is due to the fact that they do not need to bear the costs of maintaining the sales hall and sales staff.
