Excellent vibration damping
The bellows design really helps with misalignment compensation. My machine runs smoother now with less vibration noise.

Solid construction
High quality machining on the hubs. The clamp mechanism is tight and secure. Would recommend checking shaft tolerance before ordering.

Good value for industrial use
Works as expected for high torque applications. The aluminum alloy is lightweight yet durable. Delivery was slightly slower than anticipated.

Great replacement part
Replaced an old worn coupling with this Bojia unit. The difference in precision is immediately noticeable during fine cutting operations.

Perfect fit for my CNC retrofit
Installed this on my lathe servo motor and the performance is excellent. Zero backlash noticed and the build quality feels very solid.
Q: What shaft diameters does this coupling support?
A: This model supports a range of shaft diameters depending on the specific sub-model selected. Please refer to the size chart in the product images or contact us for custom bore sizing.
Q: What is the maximum operating temperature?
A: The coupling is rated for continuous operation between -20°C and 80°C. Extreme temperatures may affect the elasticity of the bellows.
Q: Can this handle angular misalignment?
A: Absolutely. The bellows element is designed to compensate for angular, parallel, and axial misalignments effectively.
Q: Does it come with screws for the clamp hubs?
A: Yes, all necessary mounting screws and Allen keys are included in the package for immediate installation.
Q: Is this suitable for high-speed spindle applications?
A: Yes, the balanced aluminum alloy construction makes it suitable for high-speed servo applications typically found in CNC lathes.
