Sphere magnet has different size by specifying the diameter. It is magnetized with North and South on opposite sides. They are more expensive because of the complicated machining required to produce them. It is durable and easier to handle than shapes with distinct edges.

Spherical disc valve is designed to meet the requirements for containment of solids, powders, and slurries. It comprises a valve body including body portions positioned adjacent one another. The body portions each have a collar portion, wherein the collar portions of the body portions are substantially aligned and together define an aperture. A valve member includes a shaft segment is positioned within the aperture, wherein the valve member is configured to rotate about an axis defined by the shaft segment for selectively closing and opening the disc valve. A clamping member is positioned about the collar portions of the body portions, the clamping member being configured to urge the collar portions toward the shaft segment and maintain the body portions adjacent one another.

Spherical plain bearings are bearings, which is used to accommodate shafts or rods with varying amounts of misalignment. It is designed to manage high radial loads and provide consistent performance under conditions of marginal lubrication, extreme speed and critical-application stress. It consists of a plain bearing and ball bushing inside a lined, cylindrical housing that minimizes friction or provides self-lubrication. These are used in railway engineering, railway station construction, bridge building, construction machinery, hydraulic steel structures, or roof designs.
