 The axle pin and support block metric universal joint made by a high-quality high-grade alloy steel. Metric single gimbal angle of 45 °, Metric double combination of gimbal angle of 90 °. 


 · Metric Dimensions follow DIN 808 


 · High-grade alloy steel 


 · Working angle of 45 ° 


 Provide optional hub and surface treatment of a variety of options. 

 Metric based on metric universal joint development of the drive shaft assembly for a wide range of applications. The total length of the system can be customized according to customer requirements. Customized system can select the various forms of the sleeve end to assembly the assembly, the drive shaft by the force can be scalable and flexible. 
 The standard stainless steel universal joint is made of 304 stainless steel, the pin and the support block hardened over the 416 stainless steel, in order to achieve higher strength, and improve the wear resistance. Fork materials for 303,304,316 L, 416 or 420 stainless steel, precisely match the customer's application. In addition, to protect the environment, the pin and the support blocks can be added lubrication protective sleeve, or more advanced stainless steel upon request. Corrosion resistance standard working angle of 35 °, you can use the protective sleeve further protection in harsh environments. 
 Appropriate assembly can be designed according to customers' unique applications. 

 · Drive and driven two-axis constant speed operation 


 · Quick replacement 


 · Custom designed to meet specific application criteria. 

 The needle bearing universal joint configuration pre-lubricated needle bearing. The needle bearing universal joint is designed for low backlash of similar robots and precision instruments, precision positioning requirements and to maintain the continued operation of the application.
