Center Rails - Heel No Groove Oil Groove Option

This center rail design is used inside injection mold tooling where long, straight linear motion is required for consistent movement of slide plates and undercut control components. The heel is built as a no-groove option, helping match specific mounting interfaces and limiting unintended lubricant routing between mating parts.

In automotive connector and terminal molds, these rails support smooth cycling and stable alignment under repetitive load. The availability of an oil groove setup allows engineers to tune lubrication behavior to the plant’s maintenance interval and expected wear rate.

For appliance and consumer electronics housings, rail thickness and width options (T = 10, 15, 20, 25 mm; W = 12, 15, 20 mm) help integrate guidance without redesigning the slide plate envelope. In medical device mold applications, predictable lubrication and wear-focused steels help maintain dimensional stability over high shot counts.

• No-groove heel supports controlled lubricant flow and predictable rail behavior
• Oil groove option enables lubrication tuning for stable sliding

This product is manufactured from selectable tool steels: SKS3 or HPM2T, both chosen to balance wear resistance with sufficient toughness for guided motion parts. The best-fit choice depends on your expected sliding duty, lubrication quality, and allowable risk of chipping under shock loads.

SKS3 is a low-alloy, wear-oriented steel typically used in applications where dimensional stability and machinability matter. For higher surface durability under lubrication, HPM2T is often preferred due to its design intent for sliding wear performance.

• Hardness (HRC): This page does not provide an HRC value in the supplied specifications, so select based on your supplier’s heat-treatment schedule for the chosen grade.
• Heat treatment state: Not specified in the provided data; plan on a standard tool-steel hardening route (quench & temper) appropriate to SKS3 or HPM2T.
• Trade-off: Higher hardness improves wear resistance but can reduce toughness; confirm shock-load requirements for your slide system.

Selection starts with matching the rail envelope to the slide plate and guidance block geometry. Choose the rail thickness T from 10, 15, 20, or 25 mm and the rail width W from 12, 15, or 20 mm to fit the designed contact surface and mounting clearance.

Then select the rail length L. Available length options include L = 100 mm, 40 ～ 95 mm, 40 ～ 150 mm, and 40 ～ 100 mm. Use the longest length that still satisfies your end-stop and slide stroke constraints, since length directly affects the supported guidance span.

• For bolt integration, match the bolt hole pitch A range: 6 ～ 19 mm or 8 ～ 42 mm, based on the mounting layout of your mold base.
• Heel without groove vs oil groove: keep the heel interface configuration consistent with the mating rail seat to avoid lubricant misrouting.

Tolerances are not provided in the input data; validate fit using your assembly drawing and the machine surface finish requirements for slide rails.
