Yokohama PROTEX features a special polyester fabric with elongation at break 1.8 times higher than Nylon fabric. Nevertheless, belt stretch under operating tension is less than that of conventional polyester fabric belts.
Comparison of belt stretch at normal & abnormal operation
| PERMANENT ELONGATION | TAKE-UP TRAVEL | |
|---|---|---|
| NYLON FABRIC: | 1.3 - 1.8% | over 2.4% |
| CONVENTIONAL POLYESTER: | 0.5 - 1.0% | over 1.5% |
| PROTEX: | 0.5 - 0.7% | over 1.0% |
UR covers were initially developed by Yokohama to handle heavy limestone rock before and after primary crushers. UR cover belts have succeeded in improving belt life with superior impact and gouge resistance features superior to that of RMA-1 cover belts.
PROTEX belt absorbs impact like no other belts.
PROTEX BELTS = TOUGH, FLEXIBLE, AND LOW-STRETCH
Let us show you how Yokohama PROTEX belts can take the abuse & deliver!
