ISO 9448-6 Guide Bushings Long Version with Collar

These ISO 9448-6 guide bushings are used in injection molds and die tooling where the leader system must maintain stable guided motion over long travel. The long-body format helps reduce misalignment as ejector and die components move through their full stroke, which is especially beneficial in long-travel applications.

• Automotive connector and housing molds: Fit the bushing in the guide layout to support consistent alignment during repeated opening cycles, helping reduce wear-related clearance growth.
• Appliance and industrial enclosure tooling: Use the collar version to improve assembly repeatability and keep the guide set positioned during clamp and production loads.
• Progressive or die inserts with extended stroke: The sintered FE self-lubricating feature supports long-term lubrication without frequent maintenance, improving stability when lubrication access is limited.

With a diameter range of 25–50 mm and length options of 55–131 mm, this variant is suited for long-length die guide integration while maintaining the ISO 9448-6 geometry.

This guide bushing variant specifies a sinter FE self-lubricating metal structure. The sintered material acts as a long-term lubrication reservoir, supporting stable friction behavior during repeated sliding under load.

• Wear resistance vs. toughness trade-off: The sintered FE formulation is optimized for running performance and steady lubrication rather than maximum impact toughness, which suits guided, controlled motion.
• Heat treatment state: The provided data describes sintered FE lubrication for long-term stability; no specific steel grade, quench & temper, nitriding, or HRC value is stated in the supplied specifications.
• Manufacturing process: The bushing is produced using a sintered** FE** approach, forming the lubrication-capable structure in the bushing body.

If you need a comparison to quenched-and-tempered guide steels or nitrided steel bushings, confirm available material/heat-treatment options with your exact tolerance and load requirements, since only sintered FE is specified here.

Select the guide bushing by matching both diameter (D) and length (L) to your mold’s guide pin/core-and-cavity spacing and guide support span. This product offers D = 25–50 mm and L = 55–131 mm, enabling selection for different long-travel strokes.

• Step 1: Match diameter: Choose a bushing with D that corresponds to your guide leader/pin diameter and the required running clearance for guided motion.
• Step 2: Match axial support length: Select L within 55–131 mm so the bushing supports the leader across the full functional travel and maintains alignment.
• Step 3: Confirm ISO 9448-6 layout: Use the collar-based arrangement consistent with ISO 9448-6 die guide integration to ensure correct seating and positional repeatability.

Because tolerance data is not provided, validate fit by referencing your mold designer’s clearance targets and the ISO 9448-6 interface requirements for your specific leader dimensions.
