A special bearing is a special type of roller bearing. It has a large bore and is used to transmit radial and axial forces. It has a special outer race that allows it to rotate freely and not impose a bending moment on the shaft. This type of bearing has two components. One is hard steel, and the other is made from bearing bronze. It is designed for high-speed applications and has a very low operating temperature.

A cylindrical roller bearing has a spherical O.D. and fits inside an outer sleeve with a spherical I.D. This allows it to misalign without affecting the rolling elements. Its straight inner race accommodates axial shaft expansion and provides a higher level of reliability than an outer race O.D. sliding into a housing bore. For precision and accuracy, a spherical roller bearing with a spherical O. D. is a perfect choice.

A modified deep groove ball bearing is a special type of bearing for applications where mounting is difficult. A keyway notch is provided on the face of the Inner Race that engages the keyway when the Inner Race is slid into position. The notches in the outer race are purely grease passages. Often, a cylindrical roller bearing is required to support a spherical shaft. The spherical inner race is more efficient.

These bearings are useful in many applications. The application of suitable bearings can improve efficiency, accuracy, and service intervals, and reduce cost of purchasing and operating machinery. The variety of shapes and materials available makes it easy to choose the best fit for your needs. A cylindrical roller bearing has a spherical O.D. which allows the machine to be misaligned without affecting the rolling elements. The straight inner race is also more reliable than an outer race O.D. sliding in the housing bore.

A modified deep groove ball bearing is a special kind of bearing that is used in applications where mounting the Inner Race can cause damage to the shaft. Its shaft fit has been modified to allow the Inner Race to slide easily into position. It has a keyway notch on the face of the Inner Race to engage with a key when the inner race is slid into position. The outer race notches are grease passages and are not crucial for the proper functioning of the bearing.

A modified deep groove ball bearing is used in applications where mounting is a challenge. It is designed to prevent the inner ring from galling the shaft, and has a spherical outer ring. The inner ring has a cylindrical shape, while the outer sleeve is usually threaded. This type of special deep groove ball bearing can also be customized to accommodate different threads. This type of special bearing is ideal for many different types of machines.
