Materials
Steel
Metal alloy whose main chemical element is iron, and whose carbon content does not exceed 2%.
Product
Bearing needle
A bearing needle is a circular metal pin whose diameter tolerance is very precise, i.e. less than 10 microns. The material used for its manufacture is a high-carbon steel identical to that used for bearings. This steel is heat-treated to optimize its hardness.

Alignment
Action aimed at aligning or positioning a component in relation to one or more others. Several methods can be used for this alignment operation, such as precision pins or splined pins. The use of spacers makes it possible to use the inside diameter for the passage of a screw, and also to achieve weight savings.

Product
Sockets
A bushing, synonymous with a spacer, is a rigid cylindrical part that can have 3 functions. The first is to join two others and keep them at a fixed distance apart. The second is to center or align 2 components, in which case the outer diameter of the spacer must be very precise, to the order of ten microns. Finally, the third function, known as compression spacer, is designed to reinforce a component, usually of lesser strength than the spacer, i.e. plastic. In the second and third functions, the spacer is hollow, i.e. a screw passes through its inside diameter, which may also be the case for the first function.

Ground pin
The ground pin is a circular metal pin whose diameter tolerance is very precise, i.e. less than 10 microns. This precision is achieved by a secondary grinding operation. This precision will enable the rectified pin to fit perfectly into the housing(s) in which it will be engaged. This precision of a few microns on the diameter can also be used for very precise positioning.
