Chain coupling is extremely simple but provide a compact and flexible coupling that is suitable for an extremely wide range of applications. Because of the design, the torque is distributed throughout the roller chain and sprocket teeth so there is an even amount of torque distributed throughout the coupler when in motion.

Another good thing about a roller chain coupling is that the sprockets and chain produce a slight clearance, which means that absolute shaft alignment is not requited for the coupling to function, however it is highly recommended to have the shafts completely aligned, if possible.

The cover (housing) is manufactured out of high-quality aluminum, includes seals, and is painted yellow. Not only does having a coupling cover provide a huge safety benefit, but it also keeps lubricant on the chain, and it will make the whole coupling assembly look neat and clean.

How to install chain coupling

Installing a complete roller chain coupling is a simple and easy task. Refer to the instructions below for the details on how to install.

Important Notes:
1. During high speed operations or conditions of large vibration, use locking cement when fastening bolts/ screws.
2. Install a coupling cover when there is a risk of chain breakage or any safety hazard factors.
3. Ambient temperature range is -10° to 60° Celcius. If you are using a roller chain coupler outside of this range, please contact our customer support team to consult with for solutions.

Step 1:

Place the oil seals supplied with the coupling cover onto the sprocket halves.

Step 2:

Adjust the angular misalignment (“α” symbol) so that the width of the tooth surface (T) is the same around the circumference of the sprockets, the allowable angular misalignment is 1°. Next you will place a straight edge at the bottom of the corresponding teeth of the two sprockets and adjust so that the offset misalignment is minimized. The allowable offset misalignment (ε) is 2% of the chain pitch. However, when the sprocket speed is 1/3 or more of the maximum speed the allowable angular and offset misalignments are 0.5° and 1% of the chain pitch.

Step 3:

Measure the distance between the sprocket faces (C) and firmly fasten the sprocket halves to the shafts.

Step 4:
Lubricate the coupling chain with chain lube which we also can supply, then wrap the chain around both sprockets and fix with connecting pin. When it comes to lubrication for the chain you can apply chain lube regularly or install a coupling cover filled with grease/lube and change every 1,000-2,000 hours depending on the application and chain lube used. To find out the best lubrication to use and re-lube schedule, contact our customer support team.

Step 5:
Fasten the coupling cover firmly and do not forget to use the supplied seals.
