Products Description

Product Name: Precision Tapered Transmission Shaft

Product Overview

This product is a silver-gray metallic shaft component featuring a slender cylindrical body (length 50mm, diameter Φ10mm). One end has a 1:50 tapered structure (tip diameter Φ2mm), while the other end includes a Φ3mm positioning hole. The surface undergoes mirror polishing (Ra ≤0.4μm), presenting a metallic silver luster. Made of high-carbon chromium steel (SCr420), it is designed for high-precision transmission and positioning applications.

Design Highlights

Tapered End Design

  • 1:50 taper enables rapid locking (compatible with Morse taper tools).
  • Tip diameter Φ2mm enhances insertion stability.

Structural Reinforcement

  • Circumferential grooves (depth 1mm) distribute stress, improving fatigue life by 50%.
  • Tapered wall thickness design (Φ12mm → Φ10mm) prevents fracture risks.

Surface Treatment

  • Mirror polishing (Ra ≤0.4μm) reduces friction coefficient (μ ≤0.1).
  • Optional hard chrome plating (thickness 50μm) for enhanced wear resistance.

Customization Service

✅ Support Custom Production:

  1. Provide 3D models (STEP format) to optimize taper/hole parameters.
  2. Material upgrades available (e.g., Inconel 718 superalloy).
  3. Surface treatment customization (DLC coating / anodizing).

⚠️ Requirements:

  • 3D models and tolerance documentation (ISO 2768 standard) required.
  • Complex structures may incur mold development fees (¥3,000–8,000).
