Guide Rod and Guide Bushing
A guide rod and guide bushing system is a precision alignment assembly used in molds, dies, and industrial machinery to ensure smooth, accurate, and stable linear movement between moving components. The guide rod provides rigid structural support, while the guide bushing ensures low-friction guiding and precise alignment during operation.
- 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 guide rod and guide bushing combination improves tooling efficiency by maintaining precise alignment, reducing friction, and minimizing mechanical wear during repeated high-cycle operations. Compared with basic guiding systems, it offers higher stability, smoother motion control, and extended service life under continuous production conditions. This system is widely used in injection molding, stamping dies, automotive tooling, and precision machinery where accurate alignment, reliable operation, and reduced maintenance costs are essential for consistent product quality.
Three Key Customization Aspects, Tailored to Your Needs
Matching different customization methods to meet various requirements.
Precision Manufacturing, Excellent Quality
High Hardness
Strong 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.
