What to consider when buying bearings

 

Mechanical bearings are typically used in applications where it’s necessary to constrain the relative motion. The reason why these mechanical components are so great is that they enhance speed and efficiency. Cars, computers, and medical devices make use of bearings to reduce mechanical friction. If you work in the automobile or medical industry, you are probably looking to buy bearings. Finding a reliable supplier is not difficult. What is hard to do is choose the right elements for your specific application. Bearing selection is complicated. If you are in the market for mechanical components, take into account the following aspects.

Types of bearings

There are many types of precision-made components, each one being designed and used for specific purposes. The most popular types of mechanical components are:

  • Ball bearing Rolling-element bearings are used for applications involving moving parts and where there’s a lesser load requirement. They are most commonly used for hard drives.
  • Roller bearings. They use cylinders to maintain the separation between moving parts. Roller parts are often used in gearbox and turbine engine applications.
  • Thrust bearings. These particular mechanical components meet stringer specifications required for high precision applications. They can be used in nearly any application.

Size

When choosing bearings, it’s important to consider their size. You can choose the size of the mechanical components based on their load ratings touching to the applied loads. Sometimes, you have to measure the mechanical components to figure out what type you need. A fast way to figure out what size you need is to use the reference number.

Think about bearing life

As stated previously, each mechanical component serves a specific function and can only be used in certain applications. The function will be performed for a long period of time, which is the reason why it’s important to think about the life of the elements. No matter if they are correctly mounted, bearings can still fail to perform the way they should. Most are meant to be used for life, but the part rarely last a lifetime. Ideally, you should test before buying. If not, there are equations that can help you determine how much your parts will last.

Price

You can find similar products that are sold for different prices. The cost will vary greatly depending on the type of mechanical components you are interested in. It’s best to shop at different places until you find what you want at the best price.
