High-Fidelity Power Transmission: High-Performance Universal Joint Cross Series

The High-Performance Universal Joint Cross Series provides a rugged, highly flexible solution for transmitting torque through changing operational angles. Designed to bridge the mechanical gap between motors and driven shafts, this universal joint series smoothly handles angular misalignment while maintaining a compact structural profile. Perfect for normal electric motors, high-torque stepper motors, and precision industrial machinery, it ensures reliable rotary power transfer without risking rotational play or early drivetrain fatigue.

Manufactured from premium Stainless Steel or thermally treated 42CrMo / 40Cr Alloy Steel, the yokes and cross pins undergo a comprehensive quenching process to maximize core toughness and wear resistance. This series supports an expansive operational envelope, managing allowable torques from 4.5 N·m up to 1500 N·m, with maximum balanced rotational velocities scaling up to 4,000 RPM.

Core Product Advantages

• Quenched 42CrMo / 40Cr & Stainless Steel: Forged from structural-grade 42CrMo or 40Cr alloy steel subjected to an intensive thermal quenching process, or premium corrosion-resistant stainless steel.

• Bright Polished Surface Finish: Every joint features a high-grade polished surface treatment that minimizes friction zones, resists grime buildup, and provides an attractive, clean aesthetic.

• Versatile Single & Double Configurations: Available in both single-joint layouts for standard angular compensation and double-joint assemblies to bridge larger offsets and eliminate parallel shaft variations.

• Impressive 4.5 to 1500 N·m Torque Range: Engineered to scale seamlessly from light-duty positioning feedback up to demanding industrial drive configurations under heavy shock loads.

• High-Velocity Capability up to 4,000 RPM: Precision balanced to support high-speed operation up to 4,000 RPM (speeds exceeding 1,000 RPM can be fully customized for optimized dynamic balance).

• Adaptable Shaft Fixing Methods: Built to accommodate diverse industrial shaft requirements, offering reliable locking via parallel keyways with set screws, or specialized pinning channels.

• Wide Dimensional Selection: Features a highly adaptable sizing matrix with finished inner hole diameters spanning from 5mm to 50mm and outer diameters ranging from 10mm to 95mm.

• Global OEM, ODM, & OBM Customization: Backed by Apexcoupling’s advanced manufacturing facility, we offer comprehensive support for custom lengths (such as our standard 250mm line), stepped bores, and non-standard metrics built directly from your prints.
