Product Description

Introduction

The Conical Guide Bushing enhances tooling performance by improving alignment accuracy, reducing friction during motion, and extending the service life of mold and die systems. Compared with standard straight bushings, it provides better guiding stability, faster assembly alignment, and reduced mechanical wear under repeated operation cycles. This component is widely used in injection molding, stamping dies, automotive parts manufacturing, and precision tooling systems where high accuracy and reliable positioning are essential for consistent production quality.

Three Key Customization Aspects, Tailored to Your Needs

Ensure accurate movement and extend service life.

Process Customization

The process embodies technological power. The honing machine with a five-axis grinding system achieves an inner hole accuracy of up to 2 μm.

Size Customization

Pursuing perfection, non-standard sizes can be customized to meet all your requirements.

Fit Customization

The fitting gap is customized according to customer requirements, suitable for both tight and sliding fits.

Precision Manufacturing, Excellent Quality

Enhanced Hardness and Stamping Resistance

Crafted from SUJ2 material and treated with carburizing heat treatment, ensuring superior hardness, durability, and wear resistance.

1:20 Micro Conical Design

The guide posts are designed with a 1:20 ratio, allowing for adjustable fitting gaps based on mold requirements. The micro-conical fitting end face serves as a limit, ensuring precise positioning without jamming.

High Concentricity

The concentricity is high, with single-piece concentricity < 0.003 and set concentricity < 0.008.

High Precision Fit

The fit offers high precision with uniform accuracy, allowing for interchangeable use. The micro-conical fit ensures precise positioning without jamming, and the high gloss finish achieves RA < 0.4.
