Brake Linings

Product Details:

WA 42 

It is a semi- rigid non-metallic, woven asbestos friction material bonded by a high temperature impregnant to give it enhanced mechanical 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.

WA-42 is available in liner and roll form and is suitable for use under dry operating conditions (i.e. it is not suitable for use in oil).

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.

WA10

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.

When in use for an oil-immersed application, should the supply of lubricant fail, WA- 10 will continue to function and avoid immediate failure of the unit. It is available in Roll lining form only.

APPLICATIONS :-

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

Ultimate tensile strength    : 240 kg/cm2

Ultimate shear strength      : 125 kg/cm2

 Ultimate compressive strength   :    700 kg/cm2

Rivet holding capacity        : 1000 kg/cm2

Specific gravity    :   1.9

RECOMMENDED OPERATING RANGE :-

Maximum temperature      : 2600C ; Maximum continuous temperature : 1250C

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. 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 than 100°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.
