Inch Steel Ball Guide Bushings

This steel ball-guided bushing is used in injection molding and die-casting tooling where a mounted clamp needs stable, repeatable alignment. In die set operation, the ball-guided motion helps maintain correct positioning between moving and fixed halves, reducing misalignment-induced wear.

In large-mold die-casting clamp assemblies, the bushing-only supply lets mold builders integrate it directly into existing guided systems without redesigning the full mechanism. The variant’s tight inch tolerance range of 0.0005 in supports smooth motion and consistent contact geometry over many cycles.

• Mounted clamp applications needing precise guide alignment
• Inch-based guided systems where a bushing-only part is preferred for compatibility
• Repetitive use environments benefiting from steel wear resistance and controlled fit

This product is specified as a steel ball guide bushing, selected for dimensional stability and wear resistance in guided tooling. For precision motion parts, steel provides good toughness to withstand the combined effects of contact pressure and cyclic loading in clamp mechanisms.

The provided data does not list a specific steel grade, hardness (HRC), or heat treatment state (e.g., quenched & tempered, nitrided). When specifying for production, confirm the steel grade and heat treatment with your Axiom Molds quotation to ensure the desired hardness/abrasion performance and the right toughness balance.

• Wear resistance vs. toughness: higher hardness typically improves abrasion resistance but may reduce impact toughness if improperly tempered.
• Heat treatment control: critical for maintaining the tight 0.0005 in inch fit performance over time.

To select the correct bushing, match the Nom. Pin Diameter (in) and overall length L1 (in) to the mating pin/guide geometry in your clamp assembly. The available range is 1 ~ 3 in for the pin diameter and 1.875 ~ 7.375 in for L1.

Start by identifying the pin diameter used in your guided system; choose the bushing nominal diameter within 1–3 in so the ball-guided interface remains concentric and motion stays smooth. Then match L1 to the available stack-up length inside the die set clamp bracket and guided housing.

• Tight fit consideration: this series is supplied with a 0.0005 in tight inch tolerance range; verify clearance and mating bore/pin tolerances to avoid binding.
• Fixed vs. configurable: Nom. Pin Diameter and L1 are specified ranges; select the closest matched size rather than assuming configurability.
