The center spacer can be made out of the same material as the hubs, but is sometimes available in insulating acetal, which makes the coupling electrically isolating. The difference between the two styles is that single disc couplings cannot accommodate parallel misalignment due to the complex bending that would be required of the lone disc.
In general, a spacer is a solid material used to separate two parts in an assembly. Spacers can vary in size from microns to centimeters. They can be made of metal, plastic, glass, and other materials. Shapes include flat sheet, cylindrical and spherical. Two sizes of metal standoffs and one plastic standoff.
A grid coupling is composed of two shaft hubs, a metallic grid spring, and a split cover kit. Torque is transmitted between the two coupling shaft hubs through the metallic grid spring element. Like metallic gear and disc couplings, grid couplings have a high torque density. A benefit of grid couplings, over either gear or disc couplings, is ...
Shaft alignment is the process of aligning two or more shafts with each other to within a tolerated margin. The resulting fault if alignment is not achieved within the demanded specifications is shaft misalignment, which may be offset or angular. Faults can lead to premature wear and damage to systems.
The basic components of an end-face mechanical seal may be installed directly onto the shaft but a popular approach is to pre-assemble the components into some sort of package for ease of installation. [3] [4] When the components are pre-assembled onto a sleeve and gland plate, the complete assembly is called a cartridge seal. This complete ...

On a spring, the bearing area refers to the amount of area on the top or bottom surface of the spring in contact with the constraining part. [ 4 ] The ways of machine tools , such as dovetail slides, box ways, prismatic ways, and other types of machine slides are also bearing surfaces.

In aeronautics, a swashplate is a mechanical device that translates input via the helicopter flight controls into motion of the main rotor blades.
