Brake Lining
Bonded Asbestos
industrial brakes is a flexible, solid woven asbestos based friction
materials, made from yarn spun around brass-wire, which contributes
considerably to its strength Charminar bonded asbestos industrial brake
linings have a medium/high coefficient of friction combined with
moderate temperature and wear resistance. It is available in roll form
and segments, cones and special shapes can easily be cut from it. Being
a flexible material it is possible to form it to redius when fitting it
facilitate this operation, it amy be heated uniformly to a moderate
temperature to soften the impregnation. It is designed solely for use
under dry conditions Charminar. Bonded Asbestos Industrial brake
linings are supplied with both surfaces ungrounded.
Size Range (Nominal)
Supplied
in rolls of approximately 15 meters (50 ft.) in thickness from 4.8 mm
(3/16") to 19.1 mm (3/4") and in widths from 25.4mm (1") to 463.6mm
(18.1/4").
Recommended Mating Surface
Good quality clone grain ro alloy cost iron.
It steel, then forged or cole rolled with a Brinell of 2DD or over, Cast steel is not recommended for use as mating surface.

Application
Charminar
Industrial brakes is suitable for a great variety of brake and clutch
components in the general industrial field such as Industrial band and
drum brake linings, plate and cone clutch linings (on e.g., Cranes,
lifts, excavators winches, concrete mixers, drop hammers, mine winding
appliances, underground haulage, tippers, oil well draw works, road
rollers, sugar mill centrifuges) Certain heavy road transport vehicles
and tractors.
Design Value
The
coefficient of friction of dressing should be based upon the graph, the
severity of application and maximum anticipated operating temperature
being taken into accoudn. NOrmal engineering practice should be
followed in applying an appropriate safety factor to torque
requirements of brake / clutch units.
Recommended Operating Temperatures
Maximum Temperatures - 260oC (500oF)
Maximum Continuous Temperature - 125oC (257oF)
Note
The continuous temperature quoted is for constant slip conditions. For intermittent applications, bulk temperatures of 160oC are acceptable for long periods.
