Expert’s Insights on Buying Quality Bearings

Are you planning to purchase plain bearings or any other type of bearing? Buying this machine element is not an easy job. It requires proper attention, preciseness, and lots of experience. A person who’s buying this component for the first time might face a little difficulty. But not if they consider every necessary determinant. There are several essential considerations that one must acknowledge when choosing metal bearings. 

To make your shopping experience delightful, below we have given the top four factors to consider when buying these machine elements. 


There are basically two types of loads-

  • Radial load: It’s perpendicular to the axis
  • Axial load: It’s parallel to the axis

Plain bearings are designed to support the radial or axial load. Some of these components are also capable of carrying both (combined) loads. If you are looking for bearings to support the combined load, we recommend you choose composite bearings. If you want a bearing that’s capable of handling the high radial load, a cylindrical roller bearing is a perfect choice. On the other hand, if you are looking for a bearing to support lighter loads or axial loads, ball bearings will work well. 

Rotation Speed

Rotation speed is another crucial element that’s necessary to consider when choosing bearings. Some bearings are capable of handling high speeds like cylindrical roller bearings and needle bearings with cages. On the other hand, bearings without cages are perfect for withstanding average rotation speed. In some cases, you may have to compromise the loading capacity for high-speed rotation. 


If your bearing is misaligned, it won’t work well. Instead, it will affect the performance of the application. That’s why it’s essential to pay special attention to the construction of the bearings. Since you’ll probably buy bearings in bulk, it’s almost impossible to check each element carefully. Therefore the best way to ensure the components you purchased are not misaligned is choosing the right vendor. Always remember, a good vendor will always provide quality and aligned bearings. However, as you know, the market is full of plain-bearing suppliers. How to know which brand is the perfect vendor for you? We have made a separate section on this topic. Stay with us till the end, and you’ll also learn how to choose the best-bearing seller.


There are two types of bearings-  one that requires time to time lubricants and the one that doesn’t. You might know the types of bearings that need proper lubing. But have you heard of bearings that don’t need greasing? Composite bearings are the ones that are well known for their high-performance resins and minimum boiling needs.

 These types of components are best for high load and slow speed applications as they offer complete stabilization. Such bearings are generally made from fiber-reinforced resins and plastic. Other than lubrication, these types of bearings are also dust-free. The biggest reason why bearings stop working is that they get jammed due to dust and dirt particles. But these bearings are manufactured in a way that they absorb dirt and dust particles. This way, they don’t let the trash or grime stop their working.

How To Choose The Right Bearing Seller

Following are the list of things that one must check in a seller before making any final decision:

Goodwill- The higher the goodwill, the reputed the vendor is.

Reviews- Always give preference to the seller who cares about the customer’s reviews. Numbers don’t matter. What matters is if the brand resolves its customer’s issues. 

Delivery Areas- Don’t forget to check if the seller you finalized delivers in your city or not?
