Selecting the Right PTO Shaft
Choosing the right PTO shaft involves considering several parameters such as:
- Length: The distance between the drive and receiving devices
- Rated Power: The power the PTO shaft can handle
- Type and Connection Method: The type of shaft and how it connects to the devices
- Torque Transmission Capacity: The amount of torque the shaft can transmit
- Environmental Requirements: The protective cover, sealing performance, and durability
- Safety Features: Reliable anti-jamming devices, anti-jamming pins, etc.
- Compatibility: The ability of the PTO shaft to work with the devices
- Certification: CE certification to ensure compliance with international standards

Importance of CE Certification
CE certification is important as it indicates that the PTO shaft complies with the relevant regulations and standards of the European Union. This ensures the design, manufacture, and use of the PTO shaft meets the requirements of the European market, providing basic safety guarantees. It is a necessary condition for entering the market and provides a reliable guarantee for the safety performance of the PTO shaft. A PTO shaft with CE certification conveys confidence in product quality and safety.
