Ball Guide Bushings for Die Sets

Ball guide bushings are used inside large die sets to maintain consistent alignment between moving and fixed tooling during injection, compression, or die-casting cycles. In a typical setup, the bushing-only component is installed in a guide post/bushing interface to provide a stable ball-guided pathway that improves motion repeatability and reduces misalignment wear.

• Automotive and industrial die-casting alignments: Suitable for die sets requiring smooth shut-off and predictable guiding at high cycle rates. The Loctite adhesive bonding helps keep the bushing position stable through repeated thermal cycling.
• Precision forming and stamping tooling: Used where repeatable assembly of subcomponents is critical. The ball guide type supports controlled guidance while the adhesive mounting improves retention during operation.
• Large mold die-set housings and die carriers: The LBB-type construction supports consistent dimensional fit for secure placement when post diameters and bushing lengths must match tooling drawings.

This variant’s adhesive-bonded, ball-guided construction is well-suited when placement accuracy and retention are required after assembly.

The provided specification data identifies this product as a ball guide bushing with Loctite adhesive bonding, but it does not list the steel grade, hardness (HRC), or heat treatment state. Therefore, material properties such as wear resistance and toughness trade-offs cannot be verified from the supplied inputs.

• Material / heat treatment: Not specified in the input data (e.g., nitrided, quenched & tempered, or pre-hardened states are not provided).
• Hardness & wear behavior: No HRC value is included, so performance claims must not be inferred.
• Manufacturing process: The key process detail is adhesive bonding using Loctite to secure placement during die-set assembly.

If your application requires a defined wear/toughness balance, request the corresponding steel grade and heat-treatment/target hardness for this series code before finalizing the die design.

Correct selection starts by matching the guide interface geometry. Use the post diameter (PD) and the bushing length (L) from your die-set drawing to choose the closest available dimensions. This series supports PD values from 20–60 mm and offers L options of 50, 60, 80, 100, 120 mm.

• Step 1 — PD match: Select the bushing with PD within 20–60 mm that corresponds to the guide post diameter in your die set.
• Step 2 — axial engagement (L): Choose L so the bushing length supports the required guidance overlap and load path for stable alignment.
• Step 3 — LC adjustment: Verify the alteration LC range of 25–59 mm aligns with your planned L dimension alteration between tooling components.

Because this is a bonded placement component, confirm fit strategy with your assembly tolerances. The spec values are the primary constraints; any additional clearance or adhesive gap should be validated against your die-set tolerance stack-up.
