ISO 9448-6 Guide Bushings with Collar (Long)

Q: Which material option should I choose for long-run guide life: bronze-coated C40 vs sintered FE vs bronze with graphite rings?

Use bronze-coated C40 when you can support conventional lubrication and want a coating-based friction reduction. Choose sinter FE for long-term lubrication behavior over extended cycling. Select bronze with solid graphite rings when you need stable low-friction motion with reduced dependence on fresh lubrication.

Q: How do I select the correct long length (L) for an ISO 9448-6 leader-ejector-space guide application?

Pick L from the available values of 59, 79, 93, 108, 127, or 150 mm to cover your effective guide engagement length. Match the length to your die stack-up so the guide maintains alignment throughout the full press stroke. A longer L supports alignment in long-travel systems where short guides can allow drift.

Q: What hardness and wear performance specs are available for these ISO 9448-6 guide bushings?

The bushing is specified at 50–54 HRC with DB≥180 . This indicates a hardened wear-performance level suitable for repetitive press operation. Exact wear-test methodology or tolerance grades are not provided in the input data, so confirm against your tool life targets.

Q: Do I need DFC retaining clamps for die housing stability, and how does the option affect selection?

The product is available without DFC retaining clamps or with DFC retaining clamps . If your die housing design requires positive retention to prevent movement under press impacts, select the clamp-equipped variant. Use the no-clamp version when your die pocket and fit are already designed for secure seating.

Q: What diameter range (D) is covered, and how should it relate to the leader shaft diameter?

This variant covers D = 19–80 mm . Choose the diameter that matches the leader shaft/guide interface used in your ISO 9448-6 die set layout. Because tolerance values are not included in the input data, verify clearance and fit with your leader and die housing tolerance specifications during design.

Product Guide

🏭Application Scenarios+

Where it’s used: Long-travel die sets that require rigid, repeatable die alignment benefit from these ISO 9448-6 guide bushings. They are commonly incorporated into leader-ejector-space assemblies for press tooling where the moving components must stay centered over extended stroke lengths.

Automotive and industrial stamping: In housings and connector bracket dies with long travel, the collar provides controlled seating, helping maintain stable alignment over repeated cycling and preventing guide wear from shifting the stack-up.
Appliance and heavy-part forming: The 59–150 mm length range supports long ejector/leader spacing while the 19–80 mm diameter range helps match common die set leader layouts.
Multi-slide or precision ejector systems: Material options (bronze-coated C40, sintered FE, or bronze with solid graphite rings) reduce friction so guides move smoothly and consistently under continuous press operation.

Why this variant fits: Its long configuration is suited for stable die support where alignment must remain consistent throughout the full stroke, with wear performance specified at 50–54 HRC.

🔧Material & Process Details+

Materials and tribology: Selection is based on lubrication strategy and surface friction targets. Bronze-coated C40 offers a durable steel base with a friction-reducing coating for smooth motion. Sinter FE (long-term lubrication) is designed to maintain lubrication at the interface during extended service. Bronze with solid graphite rings provides dry-to-semi-dry sliding capability where graphite can sustain low friction.

Steel strength / wear performance: Regardless of material option, the bushing is specified with 50–54 HRC hardness and DB≥180 (wear-related performance parameter as provided). This hardness improves abrasion resistance and helps preserve guide geometry under repetitive press loads.

Trade-offs: Higher hardness supports wear life, but the optimum choice of bronze/graphite vs. sintered lubrication affects friction consistency and how sensitive the guide is to lubrication intervals.
Heat treatment state: Supplied as hardened for wear performance (hardness specified). Detailed heat-treatment steps (e.g., quench & temper, nitriding) are not provided in the input data.

📐Sizing & Selection Guide+

Step 1: Match diameter (D) to your leader/bushing bore interface. This long guide bushing covers D = 19–80 mm. Choose the diameter that matches your die set guide/leader dimensions to avoid binding or excessive clearance.

Step 2: Select the correct length (L) for your die spacing. Available L values: 59, 79, 93, 108, 127, 150 mm. Use the cavity/core stack-up and the effective guide engagement length so alignment is supported throughout the full stroke.

Step 3: Configure retention based on tooling design. The product can be supplied without DFC retaining clamps or with DFC retaining clamps. If your die pocket requires positive retention for stability during press impacts, select the clamp-equipped version.

Fit/tolerance considerations: Since hardness is specified but tolerance values are not included in the input data, validate final clearance against your leader shaft and guide housing tolerances during die design.
Material choice tie-in: If continuous lubrication is difficult, consider sinter FE or bronze with graphite rings for smoother motion over time.
