Bronze-Plated Short Shoulder Bushings - Demountable Style

Short shoulder bushings are typically used inside leader/ejector and die-set assemblies where precise, repeatable alignment is required under repeated press cycles.

In automotive stamping die sets, they help maintain leader alignment for moving components, reducing lateral wear and promoting stable strip and part positioning. This bronze-plated, demountable variant suits service environments because it can be installed or reworked without destroying the surrounding die structure.

For industrial appliance and metal-forming dies, the steel-backed guidance improves dimensional stability while the bronze-plated surface supports smooth sliding against mating wear partners. The demountable configuration (clips/screws) supports scheduled maintenance and quick replacement during production downtime.

• Demountable installation supports controlled assembly and faster maintenance cycles
• Bronze-plated copper alloy with steel backing provides guided motion with stable performance
• Designed for plain guide bushing roles to maintain alignment across die set builds

This bushing is built from a bronze-plated copper alloy running surface with steel backing for structural support. The bronze-plated layer offers favorable bearing behavior for sliding guidance, while the steel core helps resist deformation during repeated die-set motion.

Two construction options are reflected in the provided material data: Bronze plated and Steel. In practice, the combination acts as a wear-surface + load-bearing system: bronze plating contributes to wear resistance and smoother contact, while the steel foundation increases toughness and guidance rigidity.

• Wear resistance vs. toughness trade-off: bronze-plated surfaces improve sliding wear behavior, while steel backing maintains toughness and stiffness
• Heat treatment state: not specified in the provided data; heat-treating (e.g., quench & temper) is application-dependent and should be confirmed for your batch
• Hardness (HRC): not specified in the provided data; hardness targets should be aligned with the mating guide/leader material and load conditions

Select the bushing by matching its post diameter A and length L to the corresponding leader bushing pocket and guiding surface requirements in your die-set.

• Post diameter A (in): choose within 1 ~ 7 in based on the leader guide boss/post bore or pocket diameter.
• Length L (in): choose within 1.438 ~ 2.875 in to achieve the desired guidance overlap and shoulder engagement.

For core/cavity guidance interfaces, ensure the bushing shoulder and the guided component travel match the available stroke region. Because installation can be demountable (clips/screws) or achieved via Loctite adhesive bonding (per the description), verify fit strategy: with mechanical retention you can tolerate slight mounting clearance variations, while adhesive bonding typically requires controlled surface cleanliness and consistent mating contact.

Note: tolerance values are not provided; confirm the required fit class with your die-set tolerancing standard and the mating leader bushing/guide dimensions.
