Product Description
G & GD Type Precision Cross Shaft Universal Joint Coupling (Single & Double Joint)
High-Strength 42CrMo Alloy Steel Universal Joint | Needle Bearing & Precision Keyway Options
The G (Single Joint) and GD (Double Joint) Precision Universal Joint Coupling is designed for power transmission applications requiring high torque capacity, minimal backlash, and large angular misalignment compensation. Manufactured from high-strength 42CrMo alloy steel (with options for stainless steel SUS304/SUS316 or lightweight aluminum alloy), these universal couplings feature precision H7 tolerance bores and are available with high-speed needle bearings capable of speeds up to 4,000 RPM.
Key Advantages & Features
- Premium 42CrMo Alloy Steel Construction: Built with high-grade forged 42CrMo alloy steel hubs, heat-treated pins, and bushings for maximum fatigue strength, high torque resistance, and heavy-duty durability.
- Single & Double Joint Configurations: Available in G type (single joint) for compact angular alignment and GD type (double joint) to accommodate parallel offset alongside large angular deviations.
- H7 Precision Bore & Low Backlash: Inner bores are precision machined to H7 standards, providing minimum backlash, excellent concentricity, and smooth torque transmission.
- High-Speed Needle Bearing Option: Center cross blocks can be fitted with high-precision needle bearings, enabling operational speeds of up to 4,000 RPM.
- Large Angular Misalignment Compensation: Designed to accommodate significant operational angles without compromising power transmission efficiency.
- Corrosion-Resistant Surface Treatment: Standard black oxide finish protects components against moisture, rust, and industrial environment wear.
