Overview

This document provides detailed technical specifications and ordering information for universal straight type and flange type guide bushings used in die guide applications. The guide bushings are made of bronze with graphite (SO#50 SP2) and are designed for sliding applications with operation ambient temperatures ranging from 0 to 170°C.

1. Product Types and Materials

• Universal Straight Type Guide Bushings: Available in various diameters (d) and lengths (L), with precise tolerances for mating posts and recommended hole machining.
• Universal Flange Type Guide Bushings: Similar specifications with flange features for mounting, also available in multiple sizes.
• Material: Bronze with Graphite (SO#50 SP2), ensuring durability and low friction.

2. Dimensional Specifications

The guide bushings are specified with the following key dimensions and tolerances:

• Diameter (d): Ranges from 2 mm to 160 mm depending on the catalog number.
• Length (L): Varies typically between 10 mm and 180 mm.
• Diameter tolerance for mating post: F7 for high precision, with mating post tolerances including d8 (general high load), e7 (general light load), and f7 (high precision).
• Recommended hole machining tolerance: H7.
• Other features: Chamfers (15°), radii (R0.5 to R3), and specific dimensional allowances (e.g., L -0.1/-0.3 mm).

3. Catalog and Ordering Information

The document includes extensive tables listing catalog numbers, dimensions (d, D, L), tolerance classes (m6, F7), and product codes for each size variant. These tables facilitate precise ordering based on required dimensions and tolerances.

4. Technical Notes and Recommendations

• Sliding Direction: Specified for each catalog number to ensure correct installation and operation.
• Operation Ambient Temperature: Suitable for environments from 0 to 170°C.
• Surface Finish and Machining: Recommendations include machining holes to H7 tolerance for optimal fit and performance.

5. Summary of Critical Parameters

6. Best Practices

• Ensure mating posts conform to specified tolerances (d8, e7, f7) depending on load and precision requirements.
• Machine holes to H7 tolerance to maintain proper fit and sliding performance.
• Consider ambient temperature limits when selecting guide bushings for specific applications.
• Follow specified sliding direction and installation instructions to maximize bushing life and performance.

7. Conclusion

This technical document serves as a comprehensive reference for selecting and ordering universal straight and flange type guide bushings with precise dimensional and tolerance specifications. It emphasizes material properties, machining recommendations, and operational parameters critical for ensuring optimal performance in die guide applications.
