Advanced Precision Transmission: G/GD Series Needle Bearing & Pin Type Universal Joints

The G (Single Section) and GD (Double Section) Series represent the pinnacle of small-scale precision power transmission. Combining German manufacturing techniques with top-tier metallurgy, these universal joints are designed to handle significant angular misalignments while maintaining exceptional concentricity. Available in both robust Pin-and-Bush Type for heavy low-speed loads and Needle Bearing Type for high-speed operation, the G/GD series offers a versatile, long-lasting solution for modern industrial automation.

Core Product Advantages

• Ultra-Hard 42CrMo Steel Body: The main component is crafted from 42CrMo alloy steel, heat-treated to a hardness of HRC 48-52, while the core pins utilize bearing steel hardened to HRC 56-58 for ultimate torque resistance.

• Dual Performance Configurations: * Pin & Bushing Type: Engineered for heavy-duty, low-speed applications with a limit of 1000 RPM.

  • Needle Bearing Type: Optimized for lightweight, high-speed setups, capable of smooth operation up to 4000 RPM.

• H7 Precision & Low Backlash: Manufactured using German-inspired processes to secure an H7 internal bore tolerance, delivering tight clearance, minimum backlash, and quiet operation.

• 45° Large Angular Compensation: Supports a standard working angle within 30°, with a structural limit of up to 45° per joint to safeguard against abrupt transmission changes.

• Highly Customizable Tail Ends: Connections can be tailored into internal splines, external spline shafts, bare shafts with pinholes, keyways, square/hexagonal shafts, or miniature flanges.

• Full Stainless Steel Support: Upon request, all components (including pins, blocks, and jackets) can be fully customized using SUS304 or SUS316 stainless steel for sanitary or corrosive environments.
