Inch Self-Lubricating Square Gibs Oil-Free Heel No-Groove
Inch self-lubricating square gibs (bronze) by Lamina are designed for reliable machine slide guidance. The oil-free heel and non-oil groove construction help keep operation clean, reduce friction, and limit maintenance downtime.
- Square gib geometry with oil-free heel for stable, smooth sliding
- Non-oil groove design minimizes lubrication needs in continuous use
- Bronze self-lubricating material reduces wear and running friction
- Typical fitment for inch-based industrial guides to extend equipment service life

Product Guide
Application Scenarios+
This inch self-lubricating square gib set is used inside injection mold slide-and-rail tooling to maintain straight, stable movement during cyclic open/close actions. The bronze, self-lubricating running surface helps deliver consistent sliding with reduced friction, while the oil-free heel and non-oil-groove design support cleaner shop conditions and less lubrication-related maintenance.
Common application scenarios include:
- Automotive connector and housing molds: supports repeatable slide motion for long production runs where contamination control and downtime reduction are critical.
- Appliance and consumer electronics enclosure molds: helps stabilize undercut actuation in precision parts, improving smooth motion as wear accumulates.
- Packaging insert and trim-tooling: benefits multi-cycle workflows by limiting grease/oil carryover that can attract dust.
Choose this variant when your mold uses inch-based rail dimensions and you want oil-independent guidance to minimize periodic service while preserving sliding stability.
Material & Process Details+
The gib is made from bronze self-lubricating material, selected for its ability to form a stable sliding interface and resist wear under reciprocating motion. Bronze provides good bearing behavior and toughness for guide components, and the self-lubricating characteristics help reduce the need for external lubrication during continuous cycling.
Material trade-offs: bronze typically offers excellent wear resistance and smooth running, but it may not match the hardness levels of hardened tool steels in highly abrasive environments. For applications where extreme hardness is required, tool-steel guide components are often preferred, but they generally demand more lubrication management.

As supplied, validate wear rate and surface finish against your slide load and cycle count requirements.
Sizing & Selection Guide+
To select the correct gib, match the rail-related dimensions in your mold base and slide system. This series offers rail thickness of 0.75 in, 1 in, or 1.5 in, rail width of 1 in, 1.25 in, or 2.00 in, and rail length of 4.00, 5.00, 6.00, 8.00, 10.00, or 12.00 in.
- Step 1: measure the installed rail thickness and width in your slide plate/guide frame and choose the corresponding thickness and width options.
- Step 2: choose the rail length that covers the intended guidance travel without leaving insufficient support at the stroke ends.
- Step 3: confirm mounting hole compatibility: this series supports 2, 3, 4, 5, 6 holes or None. Select the hole count that matches your mounting pattern.
Tolerance and fit values are not provided in the data; therefore, confirm clearances in your CAD and trial-fit on the actual guide rail before final build.
