Copper Alloy Oil-Free Center Rails with No Groove Heel

This oil-free center rail is designed for use in injection mold linear guidance systems where clean motion and low maintenance are critical. In automated molding cells, the no-groove heel geometry helps prevent oil-groove features from trapping debris during frequent cycle operation.

• Automotive connector and sensor housing molds: Mount the rail to guide slide or support members for reliable in/out travel. The copper alloy’s stable sliding behavior supports repeated cycles while the oil-free design reduces contamination risk near precision surfaces.
• Medical device components (housings, caps, delivery-system parts): Use when process cleanliness is a priority. The absence of groove heel features supports a cleaner installation regime compared with grooved counterparts.
• General precision appliance molds: Employ the configurable bolt-hole pitch options to align with existing guide frames and reduce rework during tryout.

Choose the variant with the required bolt-hole pitch and rail dimensions to match your mold’s mounting layout and achieve consistent linear alignment.

The product uses a copper alloy construction intended for smooth, stable sliding under frequent motion cycles in mold tooling. For oil-free guidance, the rail design relies on controlled surface behavior and dimensional stability to maintain consistent travel without periodic lubrication spillover.

• Heat treatment: The provided specifications do not define a specific steel grade, quenching/tempering schedule, or target HRC. Therefore, no hardness or treatment claims beyond the stated material can be confirmed from the available data.
• Wear vs. toughness: Copper alloys are typically selected to balance sliding performance and acceptable toughness in guided motion assemblies; exact wear rate and toughness trade-offs depend on the exact alloy and finish, which are not specified in the input.
• Material comparison: If your application involves higher load spikes or you require higher-hardness surfaces, a hardened steel guidance element is sometimes used; however, this product’s copper alloy focus is specifically aligned to oil-free linear motion needs.

For hardness (HRC), plating/coating, and heat treatment verification, request the detailed material datasheet for series 110200066610.

Select the center rail dimensions by matching both the physical envelope and the mounting-hole layout to the mold’s guide frame or slide-plate interface.

• Rail thickness T: available in 15 mm and 15–20 mm ranges. Choose the thickness that matches the guide plate stack-up to avoid shimming or misalignment.
• Rail width W: available at 15 mm and 20 mm. Ensure the width fits the constrained guide pocket while maintaining adequate clearance to mating components.
• Rail length L: multiple length ranges are offered: 40–70, 40–110, 60–100, and 80–150 mm. Pick the length that spans the effective guidance zone without extending into interfering structure.
• Bolt-hole pitch (A, B, C): choose the model whose A and B and C match your frame spacing. Available ranges include A: 7–51.5, 7.5–89.5, 7–70, 7.5–116.5; B: 18.5–63, 20.5–102.5, 18.5–81.5, 20.5–129.5; C: 30–93, 33.5–142.5.
• Mounting holes: specified options are 2 or 3 mounting-hole pieces. Match the hole count to your base frame to minimize rework.

Tolerances are not specified in the input; confirm your fit requirements (clearance and hole-to-bolt fit) with the supplier documentation for the selected configuration.
