Overview of Guide Related Parts - Flange Type Guide Pins

This document provides detailed specifications and ordering information for flange type guide pins, including straight type (tapped) variants. The guide pins are primarily made from SUJ2 material (equivalent to AISI 52100), induction hardened to a hardness of HRC58 or higher, ensuring durability and wear resistance.

Specifications

• Material: SUJ2 (I B1 A 52100)
• Hardness: HRC58 or more, induction hardened
• Types: Straight type (tapped) guide pins with flange
• Dimensions: Various diameters (D) ranging from 20mm to 80mm, with lengths (L) in increments of 5mm and press fit areas (N) in increments of 1mm
• Thread Sizes: M8x1.25, M12x1.75, M16x2.0, M20x2.5 for tapped holes

Ordering Information

Catalog numbers follow the format: Type - Diameter (D) - Length (L) - Press fit area (N). For example, RGPA 25-200-50 or RGPL 30-200-50.

Additional options can be specified using option codes:

• HMC: Tapped hole for lifting drilled at the end (applicable for diameters 60 and 80)
• GM: Tapped hole for assist pin mounting drilled at the end (applicable for diameters 60 and 80)

Dimensional Details

The document includes detailed dimensional parameters such as guide pin diameter (D), length (L), press fit area (N), and thread depth for tapped holes. Specific thread depths are provided for diameters 60 and 80, e.g., M16×32 for 60Y80, M30×35 for 60, and M36×45 for 80.

Key Parameters and Tolerances

• Surface roughness values indicated (e.g., 1.6, 0.8)
• Angular tolerances such as 5°
• Radius specifications (e.g., R0.8)
• Pitch and diameter tolerances for press fit areas

Recommendations and Notes

• Refer to page 20 for detailed assist pin specifications when ordering with GM option
• Ensure correct selection of length and press fit area increments to match application requirements
• Material and hardness specifications are critical for performance and longevity

Summary

This technical document serves as a comprehensive guide for selecting and ordering flange type guide pins with precise dimensional and material specifications. It emphasizes the importance of hardness, material quality, and optional features such as tapped holes for lifting or assist pins to meet various industrial application needs.
