About this product
Product information from the supplier.
The KC Roller Chain Coupling is a high-performance power transmission solution engineered for industrial reliability. It consists of two precision-machined sprocket hubs paired with a robust double-row roller chain, all enclosed within a sealed protective cover. By leveraging the mechanical meshing of the chain and sprocket, it ensures efficient torque transmission while providing an exceptional ability to compensate for radial, angular, and axial displacements between two shafts.
Designed for medium to high-speed applications with small to medium power requirements, the KC series is the ideal choice for pumps, fans, compressors, and conveyors. Its simple, compact structure reduces installation complexity and maintenance overhead, offering a pragmatic and economical solution for general machinery that requires high fault tolerance and reliable operational stability in diverse industrial environments.

Frequently Asked Questions
Q: What are the primary applications for the KC Roller Chain Coupling?
The KC coupling is ideal for general industrial equipment such as water pumps, exhaust fans, air compressors, and conveyors where medium to small power transmission is required.
Q: Does the KC coupling provide vibration damping?
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.
Q: How often should the coupling be lubricated?
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.
Q: How much shaft misalignment can the KC coupling handle?
It can typically compensate for radial deviations up to 1mm, angular deflections ≤ 1°, and axial displacements of approximately 1% of the shaft diameter.
Q: What is the purpose of the outer cover?
The sealed outer cover serves two main purposes: protecting the internal chain from dust and contaminants, and retaining the lubricant to reduce wear.
Q: Is the KC coupling suitable for precision transmission?
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.
