Steel Ball Bearing Demountable Guide Post Bushings for Inch

These demountable guide post bushings are used in large-mold die-casting and demountable tooling where post systems must preserve alignment through frequent maintenance. In automotive and industrial die sets, the bushings support ball guide posts to maintain stable motion, helping keep parting-line accuracy during production and reassembly.

They are also well suited for high-cycle aluminum or zinc die-casting molds that experience repeated opening/closing and component swaps. The steel bushing-only design provides durable wear characteristics and consistent guide behavior, while the demountable approach supports repeatable positioning after disassembly.

• Die-casting demountable die sets: aligns ball guide posts to reduce drift during tool service.
• Large automotive connector/housing tooling: improves shutdown reassembly accuracy for multi-cavity modules.
• Maintenance-heavy production lines: demountable construction supports faster corrective maintenance without sacrificing alignment.

This product is made from steel, selected for reliable performance under the sliding/contact conditions typical of guide systems. In die-casting and molding press environments, the steel construction provides durability and wear resistance for bushing-only operation around ball guide posts.

• Wear vs. toughness trade-off: steel offers strong wear resistance for guide motion, while toughness supports handling and repeated demounting during maintenance.
• Manufacturing process: produced as a precision bushing insert intended to maintain dimensional stability and concentric guidance for accurate post alignment.

Note: the provided specifications do not list a specific steel grade, hardness (HRC), or heat-treatment state (e.g., quenched & tempered, nitrided). Please confirm grade/heat-treatment documentation if your application requires a target hardness or wear regime.

Select the bushing to match your inch post system by first confirming the nominal post diameter and then choosing the correct L length for your demountable die structure.

• Nom. Post Diameter (in): choose from 1–3 in to correspond to your ball guide post diameter.
• L Length (in): select from 2–7 in to ensure the bushing engagement length fits within the bushing pocket and supports the intended guide travel.

Because this is a bushing-only component, its dimensions must align with the core/cavity interface and the demountable bush pocket geometry. Use your drawing’s fit requirements to specify the appropriate assembly clearances—especially important for maintaining smooth guide motion without binding after reassembly.

If you are building multiple die modules, keep post diameter and L length consistent across cavities to reduce alignment variation between re-installed sections.
