What Is a Bearing Ring?
Whether it’s a slewing ring or an angular contact ball bearing, a Bearing Ring is an important part of machinery. It helps to reduce friction and ensures accurate rotation of an axis. A Bearing Ring can be made from many different materials, and can be used for a wide variety of applications.
A Bearing Ring is composed of an inner ring and an outer ring. The inner ring has a groove on its outer diameter, which creates a raceway for rolling elements. The rolling elements are kept in a heavily lubricated environment. This helps to prevent wear. The outer ring is attached to the mounting surface by screws or adapter plates. The outer ring also has a lubrication groove, which helps to convey lubricant to the bearing.
In a Bearing Ring, the outer ring is usually held stationery. It is screwed into place via evenly spaced mounting holes. It is then polished to a smooth finish. A smooth outer ring surface helps to prevent friction and wear. A smooth surface also helps to keep the bearing in a steady position.
An outer ring is usually a single piece, but can also be molded into a single piece cage. In a molded type cage, the balls snap into place after assembly. Depending on the type of application, a wide variety of plastics can be used. The most common are Acetal (Delrin), but other plastics are available.
In order to determine the optimal fit between the inner and outer ring of a Bearing Ring, it is necessary to consider the internal geometry of the bearing. The internal geometry of the bearing includes the curvature of the raceway, as well as the amount of radial play and axial play between the components. It’s important to choose the internal geometry of the bearing carefully. The degree of radial play is based on the curvature of the track and the amount of axial play is based on the diameter of the track.
When choosing a fit, it is important to consider the temperature difference between the two surfaces. In the case of a Bearing Ring, this difference can affect its performance. The outer ring is normally heated to a higher temperature than the inner ring. A higher temperature can affect the fit, making it easier for the inner ring to creep on the seating. This may be caused by uneven distortion on the contacting surfaces.
Depending on the type of bearing, the initial clearance may be limited. A wide inner ring is ideal for heavier loads. This provides greater support for the shaft, and provides additional space for sealing and locking devices. If the bearing is used for a light load, it may be necessary to install a looser fit. This may cause the bearing to creep on the seating. The fit between the outer ring and the retaining rings must be sufficiently large. The overlap between the retaining rings and end faces of the bearing rings must also be adequate.
