What Is a Bearing?

bronze clock bearingsA bearing is a device used to either allow movement or prevent motion. Some bearings are designed to reduce friction and facilitate the linear movement of a moving part, or the free rotation of a device around a fixed axis. Others prevent motion by controlling vectors of normal forces that have an impact on the moving parts.

A variety of materials are used to make bearings. One of these is bronze. Below is a list of reasons why bronze bearings are perhaps the best on the market. A brief description on the types of bronze alloys follows. Armed with these information, you can make smart decisions when buying bearings for your projects.

Reasons to Use Bronze Bearings

1. Hardness and Strength

Bronze bearings are harder and sturdier compared to their brass counterparts that easily become deformed.

2. Longer lifespan

Bronze bearings resist shock and impact. They are also resistant to wear and corrosion. All these contribute to the durability, functionality, and service years of the bearings.

3. Versatility

Bronze is very versatile because it comes in many types of alloys and compositions. Physical, mechanical, and metallurgical properties needed for a specific application must be considered when determining what type of bronze alloy to use.

Types of Bronze Alloys

Selecting the right alloy for your needs is essential to get utmost resistance to corrosion, and obtain the maximum service life of the bearings.

1. Tin Bronze

The addition of tin to bronze makes for a very strong and hard alloy. It provides excellent resistance to corrosion and stress. It also offers exceptional wear ability. Because of its strength, the alloy is often used for carrying heavier loads.

2. Leaded Tin Bronze

A tiny amount of lead is used in tin-bronze alloys to improve manageability. The lead makes cutting and removing of the device easier and less costly. The alloy is widely available, less expensive, and tolerates slight shaft misalignments.

3. Aluminum Bronze

This alloy is the strongest of the bearing bronze alloys. It is used in heavy load and marine applications. In could work with loads that are up to 50 percent heavier than tin alloys. Aluminium bronze alloy is characterized by having high resistance to oxidation and galvanic action, and the capability of being subjected to heat. Ductility and conformity are not its strong points, but when it comes to strength, aluminium bronze alloy is the top choice.

4. Manganese Bronze

Manganese Bronze alloy is used in heavy-duty mechanical and fresh water applications. Manganese bronze bearings have a complicated makeup. Aside from manganese and bronze, it also contains zinc, iron, aluminium, and lead. These combine to create a bearing that is strong, can work at high speeds, and resistant to corrosion. The downside is that it doesn’t handle abrasion well, so the shafts it goes with must be hard and relatively stationary.
Bronze bearings are popular due to its durability, lifespan, and versatility. Keep in mind that the best type of bearing corresponds to its intended use.
