Frequently Asked Questions
The KC coupling is ideal for general industrial equipment such as water pumps, exhaust fans, air compressors, and conveyor systems where medium to small power transmission is required.
No, the KC coupling utilizes a pure mechanical meshing structure and does not have buffering or vibration absorption capabilities. It is not recommended for high-frequency impact loads.
To maintain a long service life, it is recommended to check and apply lithium-based grease every 3 to 6 months, depending on the severity of the working conditions.
It can typically compensate for radial deviations up to 1mm, angular deflections ≤ 1°, and axial displacements of approximately 1% of the shaft diameter.
The sealed outer cover serves two main purposes: protecting the internal chain from dust and contaminants, and retaining the lubricant to reduce wear.
While highly reliable for general power transmission, it is not designed for high-precision scenarios sensitive to vibration due to its mechanical chain drive nature.

Precision in power transmission is the cornerstone of high-performance automation. When dealing with servo systems, CNC equipment, or 3D printing modules, the slightest rotational clearance can lead to significant positioning errors and accelerated component wear. The aluminum alloy double diaphragm coupling is engineered specifically to eliminate this backlash while compensating for critical alignment deviations. By leveraging the elastic deformation of stainless steel diaphragms, this component ensures a rigid yet flexible torque transfer that protects sensitive encoders and motors from axial and radial stress. For procurement managers and system engineers, selecting a reliable flexible coupling Factory means balancing torsional rigidity with lightweight construction.
