Demountable Style Bronze-Plated & Steel Oversize Shoulder Bushings (Inch)

Demountable guidance in die sets: This oversize shoulder bushing variant is used in leader/ejector-style tooling where plain guidance must stay rigid during high-cycle forming and injection-mold related operations. The demountable design supports serviceability, so worn components can be replaced without disturbing the entire die stack, helping maintain stable lead-in alignment across production runs.

• Automotive and industrial forming tool die sets: Bronze-plated options improve sliding wear performance against mating steel surfaces, reducing guide scoring during repeated cycles.
• Packaging and appliance molding inserts: The steel option provides higher stiffness for assemblies that experience greater side loads, supporting consistent cavity/side alignment during closure.
• Repair-ready precision fixtures: Oversize shoulder geometry helps locate the guide precisely in the die, while demountable mounting allows faster maintenance during scheduled downtime.

This bushing is available in Bronze plated, Steel, or Bronze, enabling engineers to tune wear resistance versus load-bearing stiffness for the guide interface.

• Bronze plated: A bronze surface layer is intended to provide favorable friction and wear behavior during sliding guidance. It typically offers a practical balance for moderate-to-high cycle die sets.
• Steel: Steel construction improves structural rigidity under side loads where toughness and dimensional stability matter for alignment.
• Bronze: Bronze can provide inherent sliding characteristics, but designers should evaluate duty load and expected contact pressure versus steel-based guidance.

Note: The provided data specifies material options and does not include a specific steel grade or heat-treatment/hardness values (e.g., HRC, nitriding, or quench & temper), so those attributes should be confirmed against the applicable DANLY IEM material documentation before final selection.

Correct selection is driven by matching the post diameter A and the shoulder/overall length L to the guide hole and stack-up depth of your mold or die set.

• Post diameter A (in): choose from 1, 1 1/4, 1 1/2, 1 3/4, 2, or 2 1/2 to match the mating bore diameter in the leader/bushing seat.
• Length L (in): select from 2.688, 3.125, 3.188, 3.375, 3.625, or 4.375 to ensure proper shoulder engagement and guidance length within the die thickness.

For oversize shoulder bushings, the shoulder location is critical: verify that the seat depth provides full support without bottoming out. Tolerance and fit should be aligned with your die machining standards to maintain concentric guidance; confirm clearance or press-fit requirements with the mating components and demountable clips/screws arrangement.

All listed dimensions are configurable via the selected variant; dimensions are not indicated as adjustable after installation.
