Inch Plain Guide Bushings (Bronze-Plated) Pressed Fit

Q: What outer diameter D2 should I use to achieve the pressed-fit retention in the guide pocket?

Use the specified outer diameter range D2 = 1.1272 ~ 3.0022 in to match the pocket/housing bore designed for a press-fit. Because this part also uses Loctite adhesive mounting , small seat variations may be better managed, but the press-fit interface geometry should still be coordinated. Confirm interference/fit strategy against your pocket tolerance stack-up.

Q: Which length options L are available, and how should I select engagement depth in the mold?

This bushing is available in discrete lengths: L = 1-3/4, 3, or 2 in . Choose the length that provides the required guide engagement depth for the leader’s travel region. Insufficient length can reduce support and increase wear; excessive length can conflict with adjacent components or clearances.

Product Guide

🏭Application Scenarios+

Where it’s used: This inch-system plain guide bushing is commonly specified in leader/ejector tooling to maintain straight alignment between die and moving frames. The bronze-plated running surface is intended to reduce friction and slow wear during repeated open/close cycles.

Scenario 1—Automotive trim & connector housings: In injection molds with slide-driven mechanisms, pressed-fit guide bushings help keep the leader motion stable under high cycle loads. The Loctite adhesive mounting supports secure retention, reducing micro-movement that can otherwise lead to alignment drift.

Scenario 2—Appliance and industrial casings: For larger die sets where side loads are frequent, the plain guide geometry promotes consistent, parallel movement. The specified inner diameter range (d) and outer diameter range (D2) allow engineers to match alignment needs in inch tooling while keeping assembly repeatable.

Scenario 3—Medical device housings (small-scale alignment): In precision housings where part straightness is sensitive, the stable press-fit and wear-managed bronze surface support predictable guide performance over service cycles.

🔧Material & Process Details+

Material behavior (bronze-plated): This bushing uses a bronze-plated surface to improve sliding performance. Bronze plating is selected to help manage friction and wear at the guide interface, supporting smoother motion and longer service intervals in repetitive mold cycles.

Wear resistance vs. toughness: Bronze-plated running surfaces are optimized for low friction and wear, trading off against deeper bulk-hardness where extreme impact resistance is required.
Heat treatment state: The provided specifications describe a bronze-plated guide bushing with Loctite adhesive mounting for retention; no specific quenched-and-tempered, nitrided, or HRC hardness value is provided in the available data.
Process notes: The component is intended for pressed-fit installation, with the adhesive mounting reinforcing retention and positioning stability after assembly.

If you need an HRC target or a specific substrate grade (e.g., H13/M2 equivalents), share your drawing requirements so the correct material definition can be confirmed for your build.

📐Sizing & Selection Guide+

Step 1—Select by inner diameter (d): Choose the bushing inner diameter within 0.7502 ~ 2.5002 in to match the leader/guide shaft size used in your mold. A close match helps maintain proper guidance without excessive clearance.

Step 2—Match the outer diameter for the bore: Verify the press-fit seat diameter using the specified outer diameter D2 = 1.1272 ~ 3.0022 in. The selected D2 must correspond to the housing/bushing pocket size to achieve the intended press-fit retention.

Step 3—Confirm length (L): The available lengths are 1-3/4, 3, 2 in (discrete options). Pick the length that matches your mold’s guide engagement depth so the leader is supported over the required travel.

Fit & tolerances: Because this is a pressed fit with Loctite adhesive mounting, you should coordinate tolerances between the bushing D2 and the pocket bore to avoid looseness or assembly interference.
Configurable vs. fixed: d and D2 are selected within the given ranges, while L is limited to the listed discrete lengths.

Frequently Asked Questions

How do I choose the correct inner diameter d for this plain guide bushing in an inch leader system?+

Select the bushing by matching the leader/shaft size to the specified inner diameter range of d = 0.7502 ~ 2.5002 in. Using a compatible d helps ensure the leader is guided with the intended clearance for stable motion. If your shaft drawing includes a tolerance band, confirm the effective clearance with the bushing’s manufacturing tolerances.

What outer diameter D2 should I use to achieve the pressed-fit retention in the guide pocket?+

Use the specified outer diameter range D2 = 1.1272 ~ 3.0022 in to match the pocket/housing bore designed for a press-fit. Because this part also uses Loctite adhesive mounting, small seat variations may be better managed, but the press-fit interface geometry should still be coordinated. Confirm interference/fit strategy against your pocket tolerance stack-up.

Which length options L are available, and how should I select engagement depth in the mold?+

This bushing is available in discrete lengths: L = 1-3/4, 3, or 2 in. Choose the length that provides the required guide engagement depth for the leader’s travel region. Insufficient length can reduce support and increase wear; excessive length can conflict with adjacent components or clearances.

Is bronze-plated surface performance appropriate for wear-critical injection cycles and side-loaded mechanisms?+

The bronze-plated surface is intended to help reduce friction and manage wear at the guide interface over service cycles. For molds with frequent motion cycles and alignment-sensitive components, the plain guide design plus secure retention (press fit with Loctite) supports stable operation. If side loads are severe, verify overall guide design and leader alignment beyond the bushing surface alone.

Does this variant include information on hardness (HRC) or specific steel substrate grade for wear/toughness requirements?+

The provided product specifications describe a bronze-plated bushing with Loctite adhesive mounting and do not list a specific steel grade or a hardness value (e.g., HRC). If your application requires substrate hardness or a defined heat-treatment state, share your engineering requirements so the correct material definition can be confirmed for the build.
