There are many different kinds of special bearings. There are those that are specialized for a single purpose, such as high-speed and high-strength, and there are also those that are multi-purpose. These types of bearings are typically found in automotive systems. These types of bearings are designed to handle radial and thrust forces. The two separate races are made of hard steel on hard steel. There are also versions that feature one part that is made of bearing bronze.

Modified deep groove ball bearings are designed for applications that involve a difficult mounting process. These bearings are made to prevent the Inner Race from turning on the shaft, which could damage it. The fit between the Inner Race and the shaft is adjusted so that the Innerrace slides easily into position. The Inner Race is provided with a keyway notch, which engages a key when the inner race is slid into position. The outer races are notched to allow for grease passages, but these aren't essential for this type of bearing.

Ladder bearings are used in balance and in certain applications where axial movement is limited. These are usually placed under each corner of the machine, where they will be protected from the floor from damage. They are usually fitted into pockets provided on the base of the machine, and the bottom races are also lined with them. To maintain the correct level of lubrication, the cage/roller assembly is fitted in these pockets. Once installed, they are sealed.

Modified deep groove ball bearings are used in applications where the Inner Race is in a tight mounting situation. The modified deep groove ball bearings prevent the Inner Race from galling the shaft, so they have a unique design that makes them difficult to mount. The shaft fit has been adjusted to make them slide easily. The Inner Race has a keyway notch on its face, which engages with a key when the inner race is slid into place. The outer races have no notch and are used for grease passages.

A modified deep groove ball bearing is a special type of ball bearing that can be used in difficult mounting situations. It is designed to prevent the Inner Race from galling the shaft. The shaft has been modified to fit the inner race, while a keyway notch is provided on the face of the outer race. Generally, the outer race does not have any notches and is simply a grease passage. This type of special bearing is often designed to prevent the shaft from turning during use.

Another type of special bearings is the modified deep groove ball bearing. It is a type of deep groove ball bearing that is used in applications where mounting is difficult. A modified deep groove ball bear has a keyway on the inner race. When the inner race is slid into position, the keyway is engaged with the keyway notch on the outer race. It is a unique bearing that is not a standard deep groove ballbearing.
