Inch L-Gibs for Gib Assemblies Non-Oil Groove

This non-oil groove L-gib style guide rail is used in injection mold tooling wherever linear slide alignment must stay consistent without relying on oil delivery to the contact surfaces. In mold base slide systems—such as shut-off or moving mold shoe assemblies—the rail’s clean, oil-free motion supports repeatable positioning and reduces contamination risk in precision cavities.

It is also suitable for precision lifter and undercut actuation mechanisms where debris control and stable guidance under intermittent loads are critical. The oil-free groove concept helps maintain sliding performance over repeated cycles, which is valuable when mold area cleanliness is tightly controlled.

• Used with inch gib assemblies for machine slide and positioning systems to maintain stable alignment.
• Copper alloy construction supports wear resistance in continuous operation.
• Heel geometry supports consistent guidance under load, helping reduce stick-slip during travel.

The rail is described as a copper alloy construction. Copper alloys are commonly selected for guide components because they provide good wear resistance and stable sliding behavior against mating gib surfaces during repeated travel.

While this product page does not provide a specific copper alloy designation, hardness and heat-treatment state are not explicitly stated in the supplied data. Therefore, exact values such as HRC and whether the parts are quenched & tempered, nitrided, or otherwise heat treated cannot be confirmed from the provided specifications.

• Wear vs. toughness: copper alloys typically emphasize galling resistance and smooth sliding, trading off the very high hardness seen in fully hardened tool steels.
• Manufacturing process: dimensional control for heel/rail geometry is critical for consistent gib guidance; final fit relies on the specified rail thickness/width/length and mounting hole parameters.

To select the correct L-gib components for a gib assembly, match the rail’s thickness, width, and length to the mating guide channels and the required travel length. The available rail thickness is 0.75, 0.88, or 1.25 in, and the rail width options are 0.75, 1, 1.25, or 1.5 in.

Choose the rail length based on the effective guidance span: available lengths are 2.00, 3.00, 4.00, 5.00, or 6.00 in. Heel geometry should be selected to fit the gib assembly interface: heel height options are 0.312, 0.375, 0.5, or 0.75 in; heel width options are 0.188, 0.25, 0.375, or 0.5 in.

• Confirm mounting compatibility using hole count (2, 3, or 4) and hole size (1/4 in or 5/16 in).
• If you’re designing a new tool, allow for normal assembly clearance in the slide to prevent binding; the correct fit depends on your gib assembly clearances and mating surfaces.
