1. What is the preparation for chain installation and maintenance?

First, check all equipment to ensure that are correct.

Second, Check shafts and bearing to ensure that they are level and parallel to each other, replace or rectify if necessary.

Third, By a spirit level and adjustable comparator bar or micrometer rectify any parallelism error present and mark a permanent datum lines for the adjustable shafts.

Fourth, Place respective sprockets and shafts in approximate alignment and fit the keys in accordance with correct engineering practice. Do not finally secure keys at this stage.

Fifth, Take care with the sprocket of split design, it must perfect abutting of the faces of each half, Proceed with the key fitting after the halves are finally bolted together, otherwise the key can prevent correct assembly and subsequently result in Malingering.

2. What is the wear life of the chain?

Chain wear life is typically 1.5% elongation (normal measurement 6-12) in the application of the drive, and 2% elongation in the transportation applications. Our chains can withstand up to 3% elongation, but this may damage the chain sprocket, overloaded, or increase the vibration and noise.

3. What lubricant should be used on installed chain?

This depends on the application. In general, use clean, high-quality non-detergent petroleum-based oil. Apply the highest viscosity oil that will properly penetrate the pin-bushing joint.

4. Sprocket Alignment’s significance and basic information

1 Accurately aligning the sprocket tooth faces and shafts is to provide a uniform distribution of load across the entire chain width and contribute substantially to maximum drive life.

5. When alignment is correct within closest practical limits, drive the keys home and take a final check on sprocket alignment.
