A Summary of Split Roller Bearings and their Uses

Bearings come in many forms, shapes and sizes for different applications and the most important part of replacing bearings is getting the right ones. The second most important part is getting the highest quality bearings, making sure you will be matching the quality of existing bearings and components to promote longevity. Split roller bearings are sued when it’s not possible to use normal through shaft bearings. This might be because minimum downtime is needed, or there are access issues involved. They are generally used on shafts that are supported at several points – or shafts that make access challenging. 

The different types of split roller bearings you can use

There are generally two different types of split roller bearings: fixed type (GR) and expansion type (EX).

A summary of fixed type split roller bearings

A fixed type bearing has shoulders that are integral to the roller track on the outer race. The inner assembly has similar integral shoulders, or a hardened lip on a clamping ring. It will be suitable for radial loading and axial loading alike, giving axial location to the rotating sectors of machinery. Inner race halves are accurately aligned.

A summary of expansion type split roller bearings

The main different between the two types is that the expansion type of bearing will have a plain outer race roller track. It can only support radial loads as a result, and the inner part is clamped to the shafts. It moves axially when expansion or contraction takes place.

Where are split roller bearings generally used?

Split roller bearings have several uses and applications. Some of the most common ones are conveying equipment, use in a materials processing plant, ships, and mills. Some of the specific places where you might find them are as a part of:

  • Winches
  • Conveyors
  • Mixing and stirring plant
  • Drive and transmission shafts

Bear in mind that split roller bearings can be used in many other ways too. It all largely depends on the situation, the specific application and the bearings that are currently in use that need to be replaced.

Buying the correct split roller bearings for your application

Buying split roller bearings is simple in that they are readily available, but it can be harder to know the exact type you need – size, fixed type, expansion type etc. This can dictate the type of retailer you shop with, as it’s generally more beneficial to buy from a retailer who can also offer you advice on the products you should choose. Buying from an online retailer is also a good idea because there will be a complete choice of split roller bearings for different applications.

A summary of split roller bearings and their uses

To summarise, here are some of the key benefits of using split roller bearings:

  • They can minimise downtime
  • This can in turn help you to minimise costs when using them
  • They can be used with demanding applications if needed
  • There are two types – choose the correct one for your requirements and your application
