Product Description
Introduction
Cylindrical Guide Bushing is a precision mold alignment component designed to ensure stable positioning and smooth linear movement in stamping dies, injection molds, and industrial tooling systems. Its cylindrical structure allows accurate cooperation with guide pillars, helping maintain consistent alignment between mold parts and reducing operational deviation during high-speed production cycles. It is widely used in modern manufacturing environments that require reliable precision and repeatable performance.
Manufactured from high-quality bearing steel or hardened tool steel, Cylindrical Guide Bushing provides excellent wear resistance, high strength, and long service life. Advanced CNC machining, precision internal grinding, and controlled heat treatment processes ensure tight dimensional tolerances up to ±0.002 mm. The finely polished inner surface reduces friction and supports smooth sliding motion, maintaining stable performance even under continuous load and demanding working conditions.
Cylindrical Guide Bushing is widely applied in automotive molds, electronics manufacturing, household appliance tooling, progressive die systems, and precision hardware production. It is suitable for both standard and customized mold structures, offering flexible configuration options such as inner diameter, outer diameter, length, lubrication grooves, and material selection. This adaptability makes it a reliable solution for a wide range of industrial applications requiring high accuracy, durability, and long-term operational stability.
