Oil-Free Plain Guide Rails (Copper Alloy) Heel No Groove

Q: What mounting hole configurations are available for the heel no groove copper alloy guide rail, and how do I select between them?

This rail is available in 2, 3, or 4 mounting holes (pieces). Choose the option that matches your mold slide plate bolt pattern so the rail seats squarely and maintains the designed guidance geometry.

Q: Which rail width options (W) should I use for different guided slide stiffness requirements?

The available rail width W options are 12.5, 15, 20, 25, 30 mm . Use a wider rail when you need increased guidance area and stiffness, especially if you expect higher contact load or deflection in the guided slide assembly.

Q: Why does the heel no groove design matter for mold slide alignment in oil-free applications?

The heel no groove profile is intended to provide consistent seating and guidance geometry when mounted to the plate. That consistency helps reduce the risk of misalignment-related binding during repeated slide motion, which is especially important for oil-free operation where lubrication cannot compensate for poor fit.

Q: Is this rail suitable for injection molding tooling where lubricant contamination must be minimized?

Yes. The construction is described as oil-free and made from copper alloy , aiming to keep the slide surfaces cleaner during operation. This is useful when lubricant migration could affect molded parts or nearby mechanisms.

Product Guide

🏭Application Scenarios+

Oil-free plain guide rails with a heel no groove profile are used inside injection mold tooling and production fixtures where slide motion must stay clean with minimal lubrication. They are commonly specified for ejector/actuator guided sub-assemblies, helping maintain stable alignment during repeated opening and closing cycles.

For automated mold bases and assembly platforms, the copper-alloy oil-free design supports smooth travel while reducing the risk of lubricant migration onto molded parts or optics. The heel no groove geometry helps preserve consistent seating, so the guiding surface remains properly referenced to the mounting plate.

Guided slide plates: suited to keep motion stable in oil-reduced workshops
Machine tool slide components: supports clean, repeatable positioning under frequent cycles

🔧Material & Process Details+

This variant is made from a copper alloy, selected for controlled friction and smooth sliding behavior in oil-free motion environments. Copper-based alloys are commonly used where surface interactions must remain stable without relying on frequent lubrication.

Material behavior is a trade-off: copper alloys typically provide good wear resistance for sliding, but their toughness and load capacity can be more sensitive to contact pressure and misalignment than harder tool steels. Because no specific hardness or heat-treatment condition is provided in the available data, hardness values (e.g., HRC) and whether the part is quenched & tempered, nitrided, or pre-hardened cannot be stated here.

Oil-free copper alloy: optimized for clean sliding and reduced contamination risk
Tool steels (for comparison): offer higher hardness, but may require additional anti-wear surface management to achieve comparable oil-free running

📐Sizing & Selection Guide+

Choose the rail width W to match the guided interface length and stiffness required by your mold’s slide plate. Available widths are 12.5, 15, 20, 25, 30 mm; select the smallest width that still maintains stable contact under your expected loading and deflection.

Next, match the number of mounting holes to your base plate design. This product supports 2, 3, or 4 mounting holes (pieces), allowing selection of a configuration that aligns with your bolt pattern or clamp layout.

Core/cavity-related fit: ensure the seating plane and rail alignment are consistent, since heel no groove geometry depends on proper reference during installation
Tolerance considerations: align and torque-mount within your standard assembly tolerances to avoid binding; copper alloy guide surfaces can be sensitive to angular misalignment

Frequently Asked Questions

Can I confirm the hardness (HRC) and heat treatment state from the provided specifications?+

No. The available data lists rail width W and the number of mounting holes, but it does not provide hardness (HRC) or heat-treatment details such as quenched & tempered or nitriding. For hardness and treatment requirements, confirm with the supplier documentation for this exact series code.
