Metric Steel Detachable Ball Guide Bushings

This detachable metric ball guide bushing is used inside large mold/die tooling where repeatable die alignment and low-friction motion are critical. The detachable mounting style supports planned maintenance without full disassembly, helping reduce downtime during long production runs.

• Automotive and industrial die casting tooling: Used to maintain controlled ball-guided travel between die components, supporting stable alignment under repeated opening/closing cycles. The steel construction helps preserve dimensional stability for consistent guiding performance.
• Large housing and structural parts molds: Helps keep motion smooth and alignment repeatable during high-load actuations. This variant’s metric dimensions integrate well with standard die assemblies and guiding layouts.
• Precision repair and rebuild scenarios: Because the bushing is detachable, engineers can service worn or contaminated guide components quickly, improving maintainability while keeping guidance geometry accurate.

These metric ball guide bushings are made from steel, selected to maintain dimensional stability in die environments where alignment accuracy and smooth motion must be retained over time. In guiding applications, steel provides a good balance of stiffness and wear resistance for the sliding/rolling interface supported by the ball-guided system.

• Heat treatment state: Not specified in the provided data, so select a process suitable for the intended wear/impact balance and expected operating conditions (commonly hardened and tempered for service stability).
• Hardness and trade-offs: Specific HRC value is not provided. Generally, higher hardness improves wear resistance but can reduce toughness; pairing hardness with adequate tempering helps manage the toughness requirement for repeated die cycles.
• Material comparison: Compared with aluminum or non-ferrous options, steel better resists dimensional change under load and better supports long service life in large mold and die casting environments.

Select the bushing length L and the guide dimension D to match the cavity/core alignment and the available installation envelope in your die structure. The available length range is 65 ~ 200 mm, and the available dimension D options are 25, 32, 40, 50, 63, 80 mm.

• Match D to the mating guide geometry: Choose the D size that corresponds to the ball-guided interface and the designed alignment features in the assembly.
• Set L for proper engagement: Use a length that provides sufficient guiding engagement while respecting surrounding clearances and interference limits in the large-mold/die-casting layout.
• Tolerance & fit: Because the provided data does not list tolerances, verify that your design drawings/specification require the correct class of fit for the detachable mount. Confirm mounting interfaces and any seating surfaces to ensure consistent guiding alignment after maintenance.
• Configurability: D and L are selectable from the stated ranges; other dimensional details are not provided and must be confirmed against the official drawings.
