Features of Bearing Inserts

These types of inserts are also known as adapted radial bearings. They are often used in units that are mounted and used in industries such as agriculture, food processing, and printing.

Even though bearing inserts are often sold with a housing unit, they can also be sold as a product on their own.

These inserts offer users several different features such as:

  • Housing casings that can be made from different materials such as stainless steel, cast iron or pressed steel. They can also be constructed from zinc or nickel.
  • They have the ability to handle a larger load as compared to double row or single row ball bearings.
  • The re-greasing process is easier.
  • There is anti-rotation pin option availability.

How Do They Work?

There is a more relaxed style of bearing inserts available. This type of insert has a wider inner ring in the bearing. The inner ring extends far beyond the both sides of the outer ring.

One side of the extension allows a heavy duty seal on the bearing, and the other side of the extension accommodates both a heavy duty seal and a device for locking.

These are the types of bearing inserts that are commonly used for heavier applications.

These inserts have become so highly requested that some manufacturers have started creating inserts that have both narrow and wide ring inserts in the inner bearing. The combination of these two features allows an affordable way to have a bearing that can fit any application.


If you are considering ordering bearing inserts, especially online, it is important that you fully understand the specifications of the product before placing your order.

One of the first things that you should know is that the insert bearings can possibly be made from 440 stainless steel or 52100 chrome steel. The inserts may also be made from zinc plated or nickel plated materials.

Some users prefer black oxide coverings, and this material is typically available when requested.

Customers can also specify the way they prefer the bearing to lock. For example, they may choose a squeeze collar, eccentric lock collar, or a set screw lock. The choice will be based on the particular needs of the customer.
