Plain Guide Steel Short Shoulder Bushings Press Fit Style (Inch)

This press-fit plain guide short shoulder bushing is used in injection and forming tooling where stable, low-deflection linear guidance is required without the complexity of rolling elements. Its rigid press-fit fitment helps maintain alignment between leader pins and guide systems during repeated cycling.

• Automotive connector and small-part molds: Ideal for die sets that require consistent shutoff and part alignment. The plain bore guidance supports reliable movement while resisting shift under steady loads.
• Industrial housings and cover molds: Suited for leader/ejector space applications where the short shoulder geometry provides axial positioning and reduces play in guide stacks.
• Die sets for metal forming: Works well when steel guides are needed for durable, long-run support in guiding assemblies exposed to abrasive conditions.

The available honed vs. unhoned option allows selection of surface finish to match assembly cleanliness requirements and target sliding performance.

These short shoulder bushings are supplied in steel for robust wear resistance in plain guide applications. The design assumes a rigid, press-fit installation to maximize guidance stability and reduce micro-movement that can accelerate wear.

• Finish options: Unhoned is suitable when components will be cleaned and assembled with tolerance stack-up in mind; Honed supports improved sliding consistency by providing a more controlled internal surface.
• Hardness & heat treatment: The provided specification does not list a steel grade or HRC value, so select heat treatment requirements (e.g., quenched & tempered or nitrided) based on your die set load profile and wear target.

When choosing between unhoned and honed, consider that honed surfaces typically improve running performance, while unhoned may simplify integration if downstream finishing or polishing is planned.

To select the correct bushing, match the post diameter A and overall length L to your leader and guide system requirements. Available post diameter A values are 1/2 in, 5/8 in, 3/4 in, and 7/8 in.

• Choose diameter A: Select the bushing with the post diameter that corresponds to your leader/bore mating diameter in the guide system.
• Choose length L: Select from 1 1/2 in, 1 3/4 in, or the provided additional option 1 3/4 in (as listed). Use length to achieve the required axial support and to control play in short guide stacks.
• Surface finish: Pick Unhoned or Honed based on whether you need controlled sliding surface conditions.

Because this is a press-fit style, confirm your interference and fit class per your mold design drawings; ensure the selected dimensions align with the guide housing counterbore geometry and your tolerance stack-up.
