Product Introduction

Core Product Features

The iron bushing is a precision structural component of iron shaft sleeves, protective sleeves, and bushings. It features wear resistance, high hardness, and strong compressive strength. It is mainly used for shaft hole protection, clearance filling, and component buffering. It can be processed with non-standard structures such as steps, slots, and inner holes, and is suitable for various mechanical shaft assembly systems. The iron bushing ensures stable and durable performance in demanding applications.
