A spacer is a mechanical part that links two elements of different diameters, increasing the strength and mechanical stability of an assembly.
Its main role is to maintain a constant and defined gap between two elements, often within an assembly or in overmoulding (plastic or metal)
Bar-turned spacers are mainly found in the mechanical engineering industries, as well as wherever precision parts are needed for protection and positioning (intended to be overmoulded to prevent plastic parts from deforming).

JACQUEMOUX DÉCOLLETAGE, your bar turning company for precision spacers
A bar turning specialist for over 60 years, JACQUEMOUX DÉCOLLETAGE manufactures custom spacers for the most demanding industries. Based in the heart of the Arve Valley in Haute-Savoie, the world’s cradle of precision machining, our company produces metal spacers that meet the tightest dimensional tolerances, from medium-volume to very high-volume production.
What is a bar-turned spacer?
A bar-turned spacer is a cylindrical part machined by material removal. Unlike spacers produced by cold heading or die forging, a bar-turned spacer offers superior dimensional accuracy, a high-quality surface finish and great freedom of shape: length, inner and outer diameter, shoulder, thread, groove – every detail is machined to your specifications.
This precision makes it the go-to solution for applications where the functional dimension is critical: positioning bearings, maintaining spacing in a bolted assembly, protecting components in plastic overmoulding or maintaining alignment in a transmission mechanism.
Materials available for your bar-turned spacers
JACQUEMOUX DÉCOLLETAGE machines spacers from a wide range of metals, selected according to the mechanical, thermal or chemical constraints of each application:
- Free-cutting steel : the standard choice for everyday mechanical applications, offering a good balance between machinability, strength and cost.
- Stainless steel: ideal for humid or aggressive environments or those subject to hygiene requirements, particularly in the food processing, medical and marine sectors.
- Brass: valued for its good machinability and corrosion resistance, frequently used in electrical, hydraulic and connector technology applications.
- Aluminium: for on-board spacers where light weight is a design criterion, with no compromise on mechanical strength.
- Heat-treated steels: for applications subject to high loads or wear, requiring high surface hardness.
Bar-turned spacers for every industrial sector
As a bar turning company, JACQUEMOUX DÉCOLLETAGE serves many sectors: automotive, energy, construction sector, machinery and equipment, plastics industry and paramedical. Each sector has its own requirements in terms of materials, tolerances and surface treatments. Our technical department will help you define the solution best suited to your application.
