Flexible Roll Brake lining COMPO / FERODA
Industrial band and drum brakes, Industrial band, plate and cone clutch linings (eg. cranes, lifts, excavators .winches, concrete mixers, drop hammers, mine widening appliances, underground haulages, tippers, oil well draw works, road rollers, sugar mill centrifuges), certain heavy road transport vehicles and tractors.
Flexible Roll Brake lining COMPO WA 8 solid woven, asbestos based friction material made from asbestos yarn, spun around brass wire, which contributes considerably to its strength. WA-8 has a medium/high co-efficient of friction combined with moderate temperature and wear resistance.
WA-8 is available in Roll form. Segments, Cones and special shapes can easily be cut from it. Being a flexible material, it is possible to form it to radius when fitting it. Forming can be made easier by placing the material in an oven at a temperature of not more than100°C (212°F) until it has heated throughout to soften the impregnant.
WA-8 is designed solely for use under dry conditions (i.e. it is not suitable for use in oil). WA-8 can also be supplied with both surfaces ground.
SIZE RANGE (NOMINAL):
Supplied in rolls of approximately 15 meters (50 ft) in thickness
from 4.8 mm (3/16") to 19mm (3/4") and width from 25.4 mm (1 “) to 635.0 mm (25”)
RECOMMENDED OPERATING RANGE:
Maximum temperature : 260ºC
Maximum continuous temperature : 125ºC
The continuous temperature quoted is for constant slip conditions.
For intermittent applications, bulk temperatures of 160°C are acceptable for long periods.
RECOMMENDED MATING SURFACE:
Good quality fine grained pearlitic cast .iron. Cast steel is not a
suitable mating surface but forged or cold rolled steel with a Brinell
hardness of 200 or more may be used.
