Overview

This document provides detailed technical specifications and ordering information for Universal Straight Type Die Guide Components, specifically Guide Bushings and Washers. The components are primarily made of bronze with graphite (SO#50 SP2) and are designed for precision die guiding applications.

1. Guide Bushing Specifications

• Dimensions and Tolerances: The guide bushings have nominal diameters (φd) with F7 tolerance for the sliding fit and m6 tolerance for the outer diameter (φD). Length (L) tolerances are -0.1 to -0.3 mm.
• Entry Area: The entry area has a g tolerance to facilitate smooth insertion.
• Design Features: Includes a 2-R1.6 chamfer, 15° angle, and 1.6 mm thickness at specified points.
• Material: Bronze with graphite ensures low friction and durability.
• Sliding Direction: Specified for proper installation and function.

1.1 Size Range and Catalog Numbers

The guide bushings are available in a wide range of diameters from 8 mm up to 160 mm nominal diameter. Each size has a corresponding catalog number (e.g., SOBW10, SOBW25, SOBW100) and associated washers.

1.2 Mating Post Tolerances

• d8: General use for high load applications.
• e7: General use for light load applications.
• f7: High precision applications.

1.3 Recommended Hole Machining Tolerance

H7 tolerance is recommended for the hole where the guide bushing is installed to ensure proper fit and function.

2. Washers

• Washers are matched to guide bushings by catalog number and size.
• Material is consistent with guide bushings (bronze with graphite).
• Types include washers with bolt holes and types without bolt holes (catalog numbers SOBW and SOBWN respectively).
• Dimensions include bolt mounting hole sizes, pitch circle diameter (P.C.D), and flat head screw sizes.

3. Ordering Information

• Each guide bushing and washer size has a specific catalog number for ordering.
• Ordering includes specifying nominal diameter, length, and any special features such as bolt hole presence.

4. Critical Parameters and Recommendations

• Ensure mating post tolerance matches application load requirements (d8, e7, f7).
• Maintain recommended hole machining tolerance (H7) for optimal performance.
• Use appropriate washers matched to guide bushings for assembly integrity.
• Material choice (bronze with graphite) provides low friction and wear resistance.

5. Summary of Key Dimensions (Examples)

This table illustrates typical sizes and corresponding catalog numbers for ordering.

6. Additional Notes

• The document includes detailed dimensional tables for a wide range of sizes, including bolt hole specifications and flat head screw sizes for washers.
• Chamfers and angles are standardized to ensure compatibility and ease of assembly.
• Material and tolerance specifications are critical for ensuring the guide bushings perform reliably under various load conditions.
