MRF
MUSCLEFLEX CONVEYOR BELTING TECHNICAL DATA
Belt
Designation: MRF MUSCLEFLEX belts are designated to denote the
full thickness breaking strength in kilo Newtone/Metre width and
the number of plies comprising the carcass. A Rating of 315/3 would
denote a full thickness breaking strength of 315 kN/m width comprising
3 plies of fabric reinforcement.
NOTES:
1. For
operating temperatures in excess of 125°C, the maximum operating
tension should not be more than 75% of RMBT.
2. Carcass
thickness and weights are subject to manufacturing tolerance. Belts
with values other than above can be manufactures for special requirements.
3. Load
support data is based on belt sag between idlers limited to maximum
2% of idler span and nips of maximum 10 mm with capacity utilization
above 75%.
4. All
belts are suitable for deep throughing idlers in commonly used widths
for the given rating. However, for HEAVY SERVICE belts below 800mm,
kindly refer to the MRF service Team.
