Precision Guide Bushing
A precision guide bushing is a high-accuracy mechanical component designed to ensure smooth, stable, and precise alignment between moving parts in molds, dies, and industrial machinery. The precision guide bushing is manufactured using advanced CNC machining, heat treatment, and precision grinding processes to achieve tight tolerances, excellent wear resistance, and long-term dimensional stability.
- Hardness: HRC58-62
- Material: SUJ2, S45C, 20Cr
- Tolerance Accuracy: ±0.005mm
- Processing Technology: High-frequency/Carburizing Heat Treatment
- Customization: Standard specifications in stock, non-standard can be customized
Product Description
Introduction
The precision guide bushing enhances tooling performance by reducing friction, improving alignment accuracy, and extending the service life of mold and die systems under continuous operation. Compared with standard bushings, it delivers higher stability, lower maintenance requirements, and more consistent motion control in high-cycle production environments. This component is widely used in automotive tooling, injection molding, stamping dies, and precision engineering industries where accuracy, durability, and reliable performance are essential for maintaining production quality.
Three Key Customization Aspects, Tailored to Your Needs
Matching different customization methods to meet various requirements.
Precision Manufacturing, Excellent Quality
High Hardness and Stamping Resistance
The guide bushing is made from SUJ2 material and undergoes carburizing heat treatment, offering high hardness and a 30% improvement in wear resistance.
High Fit Accuracy
Precisely matched with the guide pillar, the guide bushing and guide pillar feature high-precision sliding fit, with a gap tolerance of ±0.005mm on both sides. This ensures precise tolerances, impact resistance, and wear resistance.
High Concentricity
Concentricity within 0.01mm, with surface roughness (Ra) of 0.6-0.8. This ensures higher smoothness, better perpendicularity, and enhanced wear resistance.
High Precision
The inner and outer diameter tolerance accuracy of the guide bushing is within ±0.005mm, ensuring precise tolerances for greater durability.
