Inch Bronze-Plated Plain Guide Bushings - Demountable Style

These demountable plain guide bushings are used in leader/guide systems for die sets where alignment stability and low-friction sliding motion are critical. They are well-suited for automotive and industrial stamping tooling, where consistent leader guidance helps maintain part geometry over repeated cycles.

In applications such as electric connector and metal bracket progressive dies, the bronze-plated bearing surface supports smooth travel while reducing friction and wear. The demountable style also supports serviceability, enabling quicker replacement during maintenance windows.

They can also be applied in ejector and transfer die sub-assemblies that require reliable positioning. The available post diameter and length options allow engineers to match the guide fit and travel length, helping protect guide rails, reduce sticking risk, and extend die-set component life.

• Demountable setup: faster die-set service and maintenance
• Bronze-plated plain bearing: low friction for stable guide motion
• Multiple A and L sizes: match die core/cavity and guide spacing requirements

This product is offered in bronze-plated and steel options. The bronze-plated variant uses a copper alloy bearing surface for low friction and improved wear protection in sliding guide applications, while the underlying construction provides dimensional integrity.

For die-set guidance, the practical trade-off is that bronze-plated surfaces typically prioritize friction reduction and wear behavior, whereas steel options prioritize structural stiffness under load. Exact hardness values and heat-treatment states (e.g., quenched & tempered, nitrided) are not provided in the supplied specifications, so selection should be based on your press loads, lubrication strategy, and wear target.

• Bronze plated: low friction bearing surface; wear-protective running layer
• Steel: higher material robustness for guide components
• Selection tip: choose bronze-plated for smoother motion and reduced galling risk where appropriate

To select the correct guide bushing, match the post diameter A and overall length L to your die-set guide hardware. The available post diameter A (in) options are: 1, 1 1/4, 1 1/2, 1 3/4, 2, 2 1/2.

Choose a length L (in) from: 1.750, 1.938, 2, 2.375, 2.625, 2.875 to ensure full engagement through the guide travel zone and adequate support around the bearing area.

• Step 1: verify the leader/post OD that the bushing must accept (select matching A range).
• Step 2: confirm required bearing engagement length and select L to cover the guidance region.
• Fit/tolerance: ensure your leader/post and bushing clearances are compatible with your lubrication and expected wear over time; confirm tolerances in your die design standards since they are not listed here.

All configurations here are dimensionally configurable only through A and L; material is selected via the offered bronze-plated or steel variants.
