1. Installation
The quality of sprocket installation has a significant impact on the smooth operation of the conveyor and determines the lifespan of the conveyor chain.
Please install correctly according to the following instructions. Installation accuracy is a general value seen from the perspective of the conveyor chain itself.
If there are limitations on the accuracy of the conveyor itself, please comply with them.
1.1 Shaft installation accuracy
1.1.1 Shaft levelness
Use a spirit level to adjust the accuracy to within ±1/300.
Figure 1. Measuring shaft levelness
1.1.2 Shaft parallelism
Use a scale or similar tool to adjust the parallelism of the shaft to within ±1 mm.
Figure 2. Measuring the parallelism of shafts
1.1.3 Misalignment of a pair of sprockets
- ・Within ±1mm when the center distance is up to 1m
- ・When the center distance is between 1m and less than 10m, ± center distance (mm)1000 or less
- ・When the center distance is 10m or more, ±10mm or less

1.1.4 Fixing the sprocket
Once the sprockets are correctly positioned, they are fixed to the shaft with a key, etc. For parallel use sprockets, two or more pairs of sprocket teeth on the shaft center are aligned in phase.
If parallel use is specified and the key is processed by our company, a match mark will be stamping on the hub.
1.2 Conveyor chain rails
- 1) Make the rail joints smooth as shown in the diagram below. Remove any edges and eliminate any steps or gaps.
- 2) Remove any spatter or scale that may have been produced during welding.
- 3) During the test run, oil the chain with no load and check the condition of the chain and rail.
