Inch Ball Bearing Demountable Bushings - Steel

In large mold tooling, this demountable bush­ing style is used to maintain stable guide motion between the moving and fixed die sets. Because it is detachable (bushing only), it’s ideal for guide systems where post alignment must be preserved while enabling faster maintenance during production cycles.

• Automotive die-set alignment: In hous­ing and bracket forming or injection of interior components, the steel bushing supports repeatable positioning, helping reduce misalignment under frequent clamp/unclamp cycles.
• Die-casting and large transfer tooling: The inch sizes (post diameter 1–3 in) allow straightforward matching to common guide post standards, supporting smooth ball/guide motion in high-cycle environments.
• Precision die maintenance programs: When guide surfaces wear, the demountable approach simplifies replacement without replacing the entire assembly, reducing downtime while keeping alignment targets.

This specific variant is suited to these applications due to its steel construction for dimensional stability and its in-service replacement design.

The bushing is manufactured in steel, selected to provide dimensional stability for guide components subjected to repetitive die movement. Steel offers a good balance of wear resistance and toughness, which is important for components that repeatedly experience sliding/rolling contact and alignment loads.

Heat treatment details such as the exact steel grade and target hardness (e.g., HRC), or whether it is quenched & tempered, nitrided, or otherwise surface-treated, are not specified in the provided data. When specifying steel guide bushings for long service life, engineers typically confirm the received heat-treatment state and hardness to ensure the expected wear rate under the intended load and lubrication conditions.

• Trade-off: Higher hardness generally improves wear resistance but can reduce toughness and increase sensitivity to impact or misalignment.
• Material options: Only steel is described for this series; no alternate materials are provided in the input data.

Selection starts by matching the post diameter and the required bushing length L. This series supports post diameters in the range of 1–3 in and lengths L = 2–7 in, so choose the size that corresponds to your guide post and the available die-set stack height.

To size correctly for a guide application, ensure the bushing bore/fit matches the guide post diameter and that the installed length provides full guidance over the desired stroke range. Confirm the bushing length relative to the mating components (e.g., adjacent guide ball/runner interfaces) to avoid insufficient bearing engagement or excessive protrusion.

• Post diameter: Select a value within 1–3 in that matches your post.
• Length L: Select within 2–7 in based on your die-set clearance and guidance overlap.
• Tolerance/fit: Demountable bushings typically require careful control of clearance and alignment; verify the post-to-bushing fit requirements in your assembly drawings, since tolerance data is not provided in this dataset.

The dimensions above are the configurable ranges; exact bushing size is determined by the ordered variant within those limits.
