Heel Guide Rails Flat Heel No Groove

Heel guide rails with a flat heel and no groove are used to provide stable, low-maintenance sliding guidance inside precision mold tooling assemblies. In machining/slider or guide-plate systems, the flat heel improves rail seating consistency, helping maintain alignment between rails and associated gibs during reciprocating motion.

• Automotive and electronics housings: used in mold slide or undercut guide setups where smooth, repeatable motion reduces wear-related misalignment.
• Machine tool and precision fixture assemblies: suited for “oil-free” style operation because the no-groove configuration supports cleaner sliding paths.
• Long-cycle molding: the rail geometry supports stable retention in undercuts-plates/guide-rails-slide-plates layouts, minimizing seat rocking under load.

Choose the steel option (HPM2T or SKS3) based on required durability and tool-life targets; this variant’s no-groove heel helps keep guidance surfaces cleaner for consistent performance.

This heel guide rail is offered in HPM2T and SKS3 tool-steel options. Both are used for precision guidance where dimensional stability and wear resistance are important in sliding contact.

• HPM2T: typically selected for improved wear resistance and toughness balance for guide components; heat treatment is commonly quenched and tempered to achieve service hardness.
• SKS3: commonly used where moderate toughness and stable machining/finishing are priorities; it is also generally provided in a hardened (quenched & tempered) condition for sliding wear performance.

In sliding rails, the trade-off is usually hardness vs. toughness: higher hardness increases abrasion resistance, while lower toughness can risk micro-chipping under shock or misalignment. Specific HRC values and heat-treatment cycles are not provided in the current data, so hardness verification should be confirmed via the supplied material cert.

Select dimensions to match the mold’s guide-rail seating features and the counterpart gib/guide surfaces. This series provides rail thickness T options of 12.5–20 mm, 15–25 mm, or 20–30 mm; rail width W of 12.5, 15, or 20 mm; and rail length L of 40–80 mm, 40–100 mm, or 60–120 mm.

• Match thickness T to the pocket/slot depth so the heel seats flat without rocking.
• Match width W to the guiding surface width of the mating plate/gib to maintain contact without overconstraint.
• Match length L to the required stroke coverage, ensuring full guidance through the full travel range.
• Heel height is available at 5 or 8 mm; choose based on the required seating step and clearance to surrounding components.

Because guidance parts operate with sliding contact, confirm the intended fit clearance in the mold assembly drawings; small seating variances can affect motion smoothness and wear rate.
