DIN Standard Daycomp Headed Guide Bushings

Headed guide bushings with DAYComp composite sliding surfaces are used in injection and forming mold tooling where stable leader alignment must be maintained throughout repetitive cycles. Their headed geometry supports controlled alignment during tool motion, helping reduce side loading on moving components and improving repeatability.

• Automotive and appliance forming tools: The low-friction composite reduces dust and abrasion that can accumulate in high-cycle stamping/press sections, supporting longer wear life under continuous sliding.
• Thermoforming and heat-intensive forming inserts: This variant is suited for sections exposed to elevated temperatures, with capability noted up to 390°C depending on application/processing condition.
• General leader/ejector guidance systems: Short, medium, and long heights allow designers to match the bushing stack-up to guide length requirements while maintaining consistent guidance.

Choose the appropriate height version and diameter to ensure the composite bushing runs smoothly against the mating leader while withstanding abrasive contamination typical of production environments.

These DIN standard headed guide bushings use a DAYComp low-friction composite sliding surface engineered to resist wear caused by dust and particulate abrasion. The composite approach trades some metal-on-metal stiffness for improved tribological performance, helping extend service life in guidance areas exposed to contaminants.

• Heat/operating capability: The product data indicates processing/operating temperature levels up to 160°C, 110°C, and 390°C depending on the specific condition.
• Wear resistance vs. toughness: Composite surfaces typically offer excellent abrasion resistance and stable low-friction behavior, reducing transfer and scoring compared with unprotected sliding materials.
• Manufacturing state: No specific steel grade, quench/temper, or hardness (HRC) is provided in the available specifications, so material heat treatment and hardness values cannot be stated reliably for this series.

To select the correct headed guide bushing, match both D and L to the leader/ejector guidance requirements of your mold tooling. The available diameter range is 19 ~ 80 mm and the available length range is 35 ~ 150 mm.

• Step 1 — Choose diameter (D): Pick D within 19–80 mm that matches the mating guide/leader diameter and provides the intended running clearance for your design.
• Step 2 — Choose length (L): Select L within 35–150 mm to cover the functional guidance zone and support stable alignment during tool travel.
• Step 3 — Select height version: Use Short height, Medium height, or Long height to align the headed geometry with your stack-up and retention method.

Because no tolerance values are provided in the input data, engineers should apply their standard molding fit/clearance strategy for composite sliding interfaces based on the leader material and surface finish.
