The Kana Chain Coupling Chain is a specialized double-row roller chain designed specifically as the flexible link between two sprockets in a Kana chain coupling. It plays a central role in transmitting rotational torque while accommodating small amounts of misalignment, vibration, and shock between two connected shafts.

KEY FUNCTIONS

Torque Transmission
• Transfers torque from the driving shaft to the driven shaft through meshing with the sprockets.
• Allows the coupling to transmit power smoothly without a rigid connection.

Flexibility
• The chain’s multi-pin and roller design gives the coupling flexibility to tolerate slight angular, parallel, and axial misalignment between shafts.

Shock & Vibration Absorption
• The inherent moving links of the chain absorb some shock and vibration, reducing stress on connected equipment.

Modular & Replaceable
• The chain can be replaced independently of the sprockets, making maintenance easier.
• The “L” part number (e.g., 16018L) refers specifically to just the chain, without sprockets.

CONSTRUCTION & DESIGN

Double-Row Roller Chain
• The chain consists of two parallel rows of rollers and links, giving greater strength and torque capacity than single-row chains.
• Designed to match the pitch and width of the coupling sprockets.
