Bronze-Plated Plain Guide Bushings - Demountable Style

Demountable plain guide bushings like this are used in precision leader/ejector space tooling where repeatable alignment directly impacts part quality. In automotive connector and housing die sets, the bronze-plated plain bearing surface helps maintain stable guidance under cyclic press loads while the demountable style allows faster inspection or replacement of worn guide components.

They are also well suited for electronic enclosure dies that require consistent leader action across multiple production runs. The bronze/copper alloy body supports controlled wear, and the detachable mounting approach simplifies maintenance without fully disassembling the leader assembly.

For progressive die stations and short-stroke ejector systems, this variant supports secure, positive installation. Engineers can lock it in place using fastening hardware and, where required, Loctite to reduce shift risk during operation.

• Die sets needing guided alignment with quick servicing
• Press applications with cyclic loads and wear management
• Layouts that benefit from configurable post diameter and length

This bushing is offered in a bronze-plated plain bearing configuration with a base bronze/copper alloy body (bronze) and bronze plating on the sliding surface. The optional steel option indicates a backing/component material choice depending on the assembly requirements.

Key material benefits for die-set guidance include:

• Wear resistance: the bronze-based bearing surface and bronze plating are intended for stable friction and predictable wear during repeated cycles.
• Toughness vs. wear trade-off: bronze offers good running behavior, while steel-backed configurations can improve structural stiffness when loads and alignment stiffness are critical.

Heat treatment and hardness (e.g., HRC, nitriding, quench & temper) are not specified in the provided data, so hardness targets cannot be stated reliably here. For best results, select the material option (steel vs. bronze/bronzeblanked plated) that matches your guidance load and maintenance interval goals.

Selection is driven primarily by post diameter A and length L, which must match the mating leader/post features in the die-set. This product supports post diameter A = 1 ~ 7 in and length L = 2.438 ~ 4.375 in, enabling fit across a wide range of die layouts.

• Measure the leader/post diameter and confirm it falls within A (1 to 7 in).
• Verify required engagement length using the available mounting space, then select L (2.438 to 4.375 in) to avoid under-support or interference.

When matching core/cavity or guide plate thickness, ensure the bushing’s installed length provides adequate support throughout the stroke. Tolerance requirements are not provided in the data, so follow your die-set drawing tolerances for bearing clearance and installation fit. This product variant is not purely fixed-dimension—it is sized by the selectable A and L ranges to suit each assembly.
