Basics of wearstrip
Conveyance should be provided only on the carry-way and the return-way should be supported by the wearstrip of which both ends should be curved slightly to prevent vibrations and pulsations of the chain.
Chain Sag
The necessary slack in the chain during conveyor operation is 90 to 140 mm below the drive sprocket as shown in the above figure.
Wearstrip height
A = Sprocket pitch circle diameter - Roller dia. 2
Curve at end of wearstrip
The curve radius of the wearstrip should be larger than the backflex radius of the chain (see table below).
| RF06B-SC | RS40-SC | RS50-SC | RS60-SC | RS80-SC | RS100-SC | |
|---|---|---|---|---|---|---|
| Backbend radius R mm | 280 | 380 | 480 | 560 | 740 | 880 |
Ways to support chain
- ・Carry Way ...Make sure the chain is supported by the rollers. If supported by the plastic cover, the cover will quickly wear down.
- ・Return Way ...The whole surface of the plastic cover should be supported.
[Carry Way ]
Rail width (W)：
Generally the sprocket tooth width.
[Return Way ]
Groove width on return-way (X)：
Chain width (L) + 2～3mm
