Inch Ball Guide Bushings (Bushing Only)

This ball guide bushing (bushing only) is used in demountable boss and leader systems where repeatable die alignment is critical. In large die sets, it supports controlled ball-guided motion between die components, helping maintain smooth engagement during open/close cycles and improving positional stability across production runs.

• Automotive and heavy-duty stamping die sets: Ideal for precise guide movement in die assemblies that require frequent maintenance; the demountable boss-compatible layout enables easier service and component replacement.
• Large mold assemblies for die-casting and housings: Suited for alignment in die pairs where consistent translation reduces misalignment risk and supports stable parting behavior.
• Tooling layouts with varying guide geometry: Multiple inch post diameter and length options (2, 2 1/2, 3 in; 1 13/16–5 13/16 in) help match different die stack-ups and guide travel requirements.

Because this variant is bushing-only, it can be integrated into existing boss systems while keeping the guide function localized to the wear/fit interface.

The provided specifications for this inch ball guide bushing focus on inch dimensions and demountable boss compatibility; no steel grade, hardness (HRC), heat treatment state, or coating details are included in the source data. As a result, material-property claims such as wear resistance ratings, toughness trade-offs, or specific heat treatment (e.g., quenched & tempered, nitrided) cannot be stated accurately for this exact variant.

For engineering selection, verify the actual base material and heat treatment from the manufacturer datasheet for DANLY IEM part series 250300525316. If multiple material options are offered for the same geometry, the common design intent is to balance surface wear (often improved by harder/thermally treated states) against guiding-part toughness (to resist chipping under shock loading).

• Action: Confirm target hardness and any surface treatment to ensure compatibility with your operating load, cycling rate, and debris environment.

To size this bushing correctly, start by matching its post diameter and length L to your demountable boss system geometry. This series supports post diameter values of 2 in, 2 1/2 in, or 3 in, and lengths L of 1 13/16 in, 3 13/16 in, 5 13/16 in, or 4 in (inch configurations).

Then verify the surrounding tool interface dimensions: Dimension C is available at 5, 4, 6, or 7 in, and Dimension F at 5/16, 2 1/2, or 1 1/2 in. These dimensions typically relate to the layout/spacing within the die set and ensure proper alignment of the ball-guided motion path.

• Fit/tolerance: Because this is a bushing-only component, confirm the intended clearance/fit with the mating boss and ball guide elements in your assembly drawing.
• Configurable vs. fixed: Post diameter and L are the main configurable dimensions in this series; C and F are also variant-dependent and must match the cavity/core stack-up.
