DC-DGBI4S Flanged Guide Bushings

Q: Which short/medium/long height version should I use for limited space guide layouts?

Choose between Short height , Medium height , and Long height based on the available axial space around the guide path. In forming tools, the flanged design uses height to support alignment, so version selection affects both fit and guidance stability. Confirm flange and overall stack-up clearance against your guide blocks and surrounding plates.

Q: What process temperature limits should I consider for DC-DGBI4S during forming tool operation?

The provided specifications list temperature limits of up to 160°C , up to 110°C , and up to 390°C depending on the defined operating condition. When selecting the bushing, align the expected tool surface temperatures with the applicable limit for your process scenario. If your tooling sees variable thermal loading, verify which of the listed limits applies to your exact operating mode.

Q: How does the DAYComp sliding performance affect abrasive wear and dust adhesion in leader/ejector space applications?

This bushing is specified for low-friction DAYComp sliding performance, aimed at reducing abrasive wear and limiting dust adhesion in demanding guide environments. In applications where fine debris accumulates at the leader path, the low-friction interface helps maintain stable guiding performance over long production runs. Proper alignment (supported by the flanged design) remains important to avoid premature wear from side-loading.

Product Guide

🏭Application Scenarios+

This flanged guide bushing is designed for forming tooling where stable leader and sliding guidance is critical under repetitive press cycles. The flanged geometry helps keep the guide aligned as the tool moves, improving motion stability and reducing the risk of side-loading in the guide path.

In automotive stamping and forming, these bushings are typically installed in guide and wear zones to support long runs while limiting dust adhesion and abrasive wear. The low-friction DAYComp sliding surface is suited for environments where fine debris can otherwise accelerate wear and increase clearances.

They are also used in industrial housings and appliance forming tools that require repeatable part positioning. Select the appropriate short, medium, or long height version to match your tool layout and stack-up, helping achieve consistent fit between stationary guide elements and moving components.

🔧Material & Process Details+

The DC-DGBI4S variant uses a DAYComp composite sliding surface engineered for low friction and reduced dust adhesion. In service, this material choice targets improved wear performance in guide/sleeve applications where abrasive particles can cause progressive clearancing.

While the provided specifications do not list a specific steel grade, the key functional material attribute is the DAYComp low-friction interface, which shifts the design focus toward wear reduction rather than maximum hardness alone.

Heat performance (process temperature): use up to 160°C, 110°C, or 390°C depending on the operating condition defined for your tooling application.
Wear vs. toughness trade-off: composite sliding surfaces prioritize low-friction running behavior and abrasion resistance; overly aggressive loads or misalignment can still reduce service life.
Manufacturing process: selected to deliver a consistent sliding interface on a flanged guide bushing for repeatable tool motion.

📐Sizing & Selection Guide+

Correct selection is based primarily on D (shaft/guide diameter) and L (bushing length). Choose D = 19 ~ 80 mm to match the guide element diameter used in your mold/tool stack so the bushing can provide controlled clearance and smooth sliding.

Next, match the required guide engagement length using L = 38 ~ 125 mm. Longer L generally increases the guided contact length for improved stability, while shorter lengths can suit compact tool layouts.

Version selection: pick Short height, Medium height, or Long height to match your available axial space and desired flange support.
Fit considerations: ensure the selected D corresponds to the actual guide diameter and allows for assembly fit under production conditions.
Tool layout match: confirm that flange height and L do not interfere with adjacent plates, ejector components, or guide blocks.

For best guiding performance, confirm both diameter (D) and engagement length (L) align with the cavity/core guidance requirements and the expected wear allowance for your application.

Frequently Asked Questions

How do I choose the right D (19–80 mm) for DC-DGBI4S guide fit in my tooling?+

Select D to match the actual guide/shaft diameter used at the leader-sliding interface. The available range is 19 ~ 80 mm, so the chosen bushing should align with your tool’s guide diameter to achieve stable sliding without excessive clearance. If your design uses tight guidance tolerances, verify assembly fit and adjust for wear allowance across the expected run length.

What determines the correct L length (38–125 mm) when designing guide engagement for press/forming cycles?+

Use L to set the guided contact length in the tool stack. The specified range is 38 ~ 125 mm, where longer engagement can improve motion stability in abrasive or dust-prone environments. Ensure L does not conflict with adjacent components and that flange height matches your axial space.

Which short/medium/long height version should I use for limited space guide layouts?+

Choose between Short height, Medium height, and Long height based on the available axial space around the guide path. In forming tools, the flanged design uses height to support alignment, so version selection affects both fit and guidance stability. Confirm flange and overall stack-up clearance against your guide blocks and surrounding plates.

What process temperature limits should I consider for DC-DGBI4S during forming tool operation?+

The provided specifications list temperature limits of up to 160°C, up to 110°C, and up to 390°C depending on the defined operating condition. When selecting the bushing, align the expected tool surface temperatures with the applicable limit for your process scenario. If your tooling sees variable thermal loading, verify which of the listed limits applies to your exact operating mode.

How does the DAYComp sliding performance affect abrasive wear and dust adhesion in leader/ejector space applications?+

This bushing is specified for low-friction DAYComp sliding performance, aimed at reducing abrasive wear and limiting dust adhesion in demanding guide environments. In applications where fine debris accumulates at the leader path, the low-friction interface helps maintain stable guiding performance over long production runs.
