And working principleCore components: A roller chain coupling is normally composed of two toothed half-couplings (sprockets).

One double-row roller chain and an optional protective cover.

Half-couplings: The mainstream material is 45# steel with quenching and tempering the gear teeth are high-frequency quenched.

And the standard bore supports a parallel key or a shrink disc connection.

Chain: The GL type uses a national-standard chain (such as a 16A double-row chain with a pitch of 4mm) while the KC type uses an American-standard chain (such as a 50 double-row chain with a pitch of 875mm).

Protective cover: A split aluminum alloy housing with a built-in O-ring seal, mandatory for high-speed operation.

Transmission mechanism: The driving sprocket drives the driven sprocket through the meshing of the double-row roller chain to rigid synchronous transmission.

While installation misalignment is compensated by the clearance of the chain joints. Radial misalignment compensation: ≤0.5mm (through lateral chain swing).

Axial misalignment compensation: ≤3mm (through the chain take-up allowance). Angular misalignment compensation: ≤1° (through the self-adjusting fit of the chain and sprocket teeth).

Applicable Conditions. Shaft drives for machinery in textiles, agricultural machinery, hoisting and conveying, mining, light industry, and chemicals.

High-temperature, humid, and dusty environments (-20°C to +120°C). Small and medium-sized belt conveyors, fans, water pumps, mixing equipment, and packaging machinery.

Unsuitable Applications. Not for high-speed operation, severe impact loads, or frequent reversal. For equipment that frequently stalls or jams, such as elevators and feeders, a safety coupling should be used.

Applications requiring zero-backlash precision transmission or the transmission of axial force.
