Ribstar G (rubber V-ribbed belt)
Caution
Product Description
This belt combines the high transmission of a V-belt with the flexibility of a flat belt.
[Features]
· A high transmission capacity can be obtained. (Transmission capacity per unit width is 35 to 50% higher than standard V-belts.)
· High speed transmission is possible. (Belt weight is light and less heat is generated)
·Smooth transmission with low noise and little vibration is possible.
· High transmission efficiency is obtained. (Approx. 98% transmission efficiency under normal use conditions)
·A compact design is possible.
·Maintenance-free with long service life.
[Applications]
·Home appliances: Dryers, health equipment, grinders.
·working machine: Lawn mowers, combines, harvesters, power sprayers, engines for work equipment.
·Machine tool: NC lathes, milling machines, drilling machines, cutting machines, grinders.
·Industrial machinery: High-speed printers, mills, stirrers, blowers, generators, pumps, compressors.
·Other: Automatic doors, broadcast equipment drives, hovercraft.
