WA-8 

It is a flexible, solid woven, asbestos based friction material made from asbestos yarn, spun around brass wire, which contributes considerably to its strength.

Applications :
Industrial band and drum brake Lining; Industrial band, plateand cone clutch lining (eg. cranes, lifts, exavators .winches, conctete mixers, drop hammers, mine widening appliances, underground haulage, tippers, oil well draw works, road rollers, sugar mill centrifuges), certain heavy road transport vehicles and tractors.

Technical Data :
Friction
µ for design purposes 0.35

Size Range(Normal) :
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'')
MAGMA 23

It is a semi-rigid, solid woven asbestos based friction material incorporating zinc wire in its construction. Its specially developed impregnant has high temperature resistance, giving the material excellent anti-fade and wear properties.

Applications :
Automotive drum brakes
Industrial drum brakes
Industrial band brakes and clutches
Industrial plate clutches

Technical Data :
Friction
µ = 0.4 for design purposes (see curve)

Length Of Rolls :
Appx 15 meters for thicknesses of 4.8 mm & 6.4 mm
Appx 7.5 meters for thicknesses of 7.9 mm, 9.5 mm & 12.7 mm
WA-10

It is a semi-rigid, solid woven asbestos-based friction material with a brass wire content. It is primarily intended for use under oil immersed conditions, but can also be used dry.

Applications :
Oil immersed brakes, plate and cone clutches for industrial usage, earth-moving equipment, agricultural machinery etc.,
CR-1
 

It is a flexible moulded non-metallic friction material with a random fibre asbestos base. It possesses stable co-efficient of friction and provides consistently good performance over a fairly wide range of operating conditions.

Applications :
Automotive drum brakes.
Light trucks and commercial vehicles drum brakes.
Indusrial drum brakes, Band brakes, Moped and Scooter brakes.

Technical Data :
Friction
µ for design purposes (see curve) : 0.35 (dry)
 
CR-2

It is a flexible moulded non-metallic friction material, light grey in color and having a random fibre asbestos base. It is available inroll and strip form and is suitable for use under dry operating conditions only (i.e. it is not suitable for use in oil ).

Applications :
Scooter and moped drum brakes and clutches, automotive drum brakes, industrial drum brake, industrial band brake, excavator brakes and clutch band linings.

Technical Data :
Friction
µ for design purposes (see curve) : 0.40 (dry)
WA-42

It is a semi-rigid non-mettalic, woven asbestos friction material bonded by a high temperature impregnant to give it enhanced mehanical strength and good antifade and wear properties. The material is sufficiently flexible to accommodate small changes in radius and to make it suitable for use as a band lining. The impregnant does not soften when heated and large changes in radius should not be attempted.

Applications :
General purpose automotive drum brakes, Industrial Drum Brakes, Industrial band brakes and clutches (on e.g. excavators, cranes, lifts electro-magnetic brakes), drive shaft transmission brakes, miscellaneous friction devices.

Technical Data :
Friction
µ for design purposes (see curve) : 0.38

Size Range (Normal) :
Supplied in rolls of approximatelly 15 meters (50 ft.) for thicknesses 4.763 mm {3/16''} and 6.4 mm {1/4''} and in rolls of approximately 7.5 meters (25 feet) for thicknesses 7.9 mm {5.16''} , 9.5 mm 3/8'' and 12.7 mm {1/2''}. The widths available are from 25.4 mm (1'') to 177.8 mm (7'' ).
Asbestos Free Roll Lining 10 GG

It is one of the range of Non-asbestos Friction materials, it is a flexible moulded product, Grey Black in color and having a basis of processed mineral fibre and other metallic powder substances in a random dispersion.

Applications :
Scooter and moped drum brakes and clutches. Industrial Drum brakes. Cranes and Excavator brakes and clutch lining . Vehicle brake linings ( In selected cases ).

Technical Data :
Friction
µ for design purposes (see curve) : 0.45
