Manufacture of metal spacers

At Lemec we specialize in the manufacture of metal spacers by two processes: cold heading for big batches which offers an excellent quality-price ratio, and bar turning for smaller batches.

Lemec, as an auxiliary industry, manufactures to order, following your drawings and specifications. Send us your documentation and we will study the most suitable solution for your needs.

Manufacture of metal spacers

At Lemec, we are dedicated to the manufacture of a wide variety of metal spacers, adapting to the specific requirements of each customer.

Steel spacers

Our steel spacers are ideal for applications requiring high strength and durability. They offer robust and reliable support for any configuration.

Stainless steel separators

We manufacture stainless steel spacers that provide excellent corrosion resistance, perfect for aggressive environments where durability is crucial.

Brass spacers

The brass spacers we produce combine corrosion resistance and an aesthetic appearance, making them ideal for specific applications that require both attributes.

Copper spacers

We offer copper spacers, known for their excellent electrical and thermal conductivity, suitable for applications where these properties are essential.

Aluminum spacers

At Lemec, we manufacture lightweight yet robust aluminum spacers, perfect for applications where weight is a critical factor without compromising strength.

Custom metal spacers

Our specialty in the manufacture of metal spacers allows us to offer customized and high quality solutions. From stainless steel spacers to spacer bushings, at Lemec we guarantee products that meet your exact specifications, providing the best solution for your industrial projects. As a manufacturer of spacers and spacer bushings, we pride ourselves in offering reliable and durable products that fit the needs of your projects.

Frequently Asked Questions

How can I choose the right metal spacer for my application (automotive, electronics, machinery, hydraulics)?

Define the distance to be maintained and the load it must withstand. To avoid buckling, check slenderness (L/Øe): if the ratio is high, increase the outer diameter or add a flange/collar. Choose the type of fastening: through-hole (plain bore) or threaded (standoff), depending on assembly and tightening torque. Select material/finish based on environment and galvanic compatibility (A2/A4 stainless steel for corrosion resistance, aluminum for light weight, brass for electronics; zinc plating/nickel plating/anodizing as needed). Adjust tolerances (Øi/Øe/L), flatness, and perpendicularity of faces when precision is required. As a spacer manufacturer, we also produce custom spacers according to drawings for each sector.

How is a spacer dimensioned to avoid buckling and ensure compressive strength?

Control slenderness: high L/Øe ratios → greater buckling risk; for long lengths, increase Øe or add a flange/collar.

Define service load (static/dynamic) and material (yield strength) to estimate allowable load.

Ensure flatness/perpendicularity of faces: proper seating distributes compression and avoids settling.

Under vibration, use washers or stops to protect the spacer and substrate surfaces.

What geometric requirements are critical in precision metal spacers?

Inner/outer diameters and length with their tolerances (hundredths in Ø and tenths in L, depending on the case).

Concentricity between Øi and Øe (key if guiding screws/pistons).

Face roughness (Ra) for firm seating; chamfers to facilitate assembly.

Parallelism and perpendicularity relative to the spacer axis.

What processes are used to manufacture special spacers and when should each be applied?

Cold heading: optimal for long production runs and repetitive geometries (simple or with flanges); ensures high repeatability and lower unit cost.

Screw machining (decoletage): ideal for short/medium series and complex geometries such as internal threads, countersinks, grooves, radial holes, knurling, or very tight tolerances.

Finishes: zinc plating, nickel plating, black oxide, or anodizing (Al), depending on corrosion resistance, aesthetics, and galvanic compatibility.

What should a drawing/order include to quote the manufacturing of precision spacers?

• Material (steel, stainless steel, aluminum, brass, etc.) and treatments (heat/surface).
• Dimensions: Øi, Øe, length, possible flanges/collars, chamfers/radii.
• Tolerances (Øi/Øe/L), concentricity, parallelism, and face roughness (Ra).
• Operations: internal threads, countersinks, side holes, markings.
• Context of use (“metal spacers for automotive/electronics/machinery”), production volume, and delivery plan.
