A spacer is a mechanical part used to connect two elements of different diameters, in order to increase the strength and mechanical stability of an assembly.
Its main role is to maintain a constant and determined gap between two elements, often in an assembly, or in an overmolding (plastic or metallic).
Machined spacers are found mainly in mechanical industries , as well as anywhere where it is necessary to have precision parts used for protection and positioning (intended to be overmolded to avoid deformation of plastic parts).

JACQUEMOUX DÉCOLLETAGE, your precision spacer machining company
Specializing in precision machining for over 60 years, JACQUEMOUX DÉCOLLETAGE manufactures custom spacers for the most demanding industries. Located in the heart of the Arve Valley in Haute-Savoie, the world's cradle of precision machining, our company produces metal spacers meeting the tightest dimensional tolerances, from medium to very large production runs.
What is a cut-out spacer?
A turned spacer is a cylindrical part machined by removing material . Unlike spacers produced by stamping or die-casting, the turned spacer offers superior dimensional accuracy, neat surface finishes and great freedom of form: length, inner and outer diameter, shoulder, thread, groove, every detail is machined according to your specifications.
This precision makes it the reference solution for applications where the functional dimension is critical: positioning of bearings, maintaining spacing in a bolted assembly, protecting components in a plastic overmolding or maintaining alignment in a transmission mechanism.
Materials available for your cut-out spacers
JACQUEMOUX DÉCOLLETAGE manufactures spacers in a wide range of metallic materials, selected according to the mechanical, thermal or chemical constraints of each application:
- Free-cutting steel : the standard choice for common mechanical applications, offering a good compromise between machinability, strength and cost.
- Stainless steel : ideal for humid, aggressive environments or those subject to hygiene requirements, particularly in the food processing, medical or naval sectors.
- Brass : appreciated for its good machinability and anti-corrosion properties, frequently used in electrical, hydraulic or connector applications.
- Aluminium : for on-board spacers where lightness is a design criterion without compromising mechanical strength.
- Heat-treated steels : for applications subjected to significant stress or wear, requiring high surface hardness.
Machined spacers for all industrial sectors
As a precision machining company, JACQUEMOUX DÉCOLLETAGE serves numerous sectors: automotive , energy , construction , machinery and equipment , plastics , and paramedical . Each sector has its own specific requirements regarding materials, tolerances, and surface treatments. Our technical department will assist you in defining the most suitable solution for your application.
