Product details
Description
Enhance the precision and stability of your mechanical systems with the YWBL-WH Motor Shaft Double Coupler. Designed with a robust 40mm outer diameter, this double diaphragm coupling features a lightweight anodized aluminum alloy hub paired with high-strength stainless steel U-shaped discs.
It is engineered to transmit high torque efficiently while effectively absorbing axial, radial, and angular misalignments without introducing backlash. The secure clamp-style locking mechanism utilizes hex screws for a firm grip on 8mm to 10mm shafts, ensuring reliable performance during continuous operation.
Ideal for connecting servo motors, stepper motors, encoders, lead screws, and CNC machine tool platforms, this professional-grade accessory delivers low inertia and long-lasting durability. Whether you are building custom automation equipment or upgrading existing machinery, this component provides the stability and flexibility required for accurate motion control.
How to use
- Ensure the motor and driven shafts are clean and free of debris.
- Slide the coupler onto the shafts, adjusting for any minor misalignments, and tighten the clamp-style hex screws securely to lock it in place.

chota mota kaam ke liye mast
ye wala coupler bag me daal ke leke gayi thi project site pe transport me bhi kharab nahi hua aur 40mm diameter hone ke baad bhi weight me kaafi halka hai machine me lagane ke baad vibration kam ho gaya

sahi hai kaam chal gaya
kabhi socha nahi tha online is type ke parts thik thak milenge par mangvaya toh fitting ekdum proper baith gayi cnc machine ke liye aluminium alloy wali body kaafi halki hai aur shaft pe pakad bhi solid hai bas packing thodi loose lagi
