Structure of sheeted friction lining:
The friction lining produced by Gambit is an asbestos-free material, mould-pressed to customer's order, or pressed into sheets and cut to a customer's specification. Composition of materials applied and special regimented mixing and pressing processes allow production of homogeneous and reliable material of high friction coefficient in broad range of temperatures, low and even wear, as well as good performance, including low wear of mating surfaces, as well as quiet and stable operation. Significant use of components with high thermal conductivity ensures effective lining braking, also in applications when a braking cycle is highly intensive. Use of aramide fibres in sheeted friction lining ensures maintaining suitable elasticity and cracking resistance.
Sheeted friction lining is designated for application in disc brakes, drum brakes, conical brakes and other types of brakes applied wherever large braking forces are required; at high temperature during operation; and when high reliability of friction material and low wear of mating drum raceways is necessary. It is also recommended for use in equipment with high braking frequency. Upon customer's request we can produce reinforced and cut sheeted friction lining, designated for application in drum brakes.
Hardness categories and executions
Sheeted friction linings GC-E, GC-ES, GC-MK and GC-PZ are produced in two standard degrees of hardness and manufactured according to a version chosen by a customer. The versions are marked as follows:
+ Z - reinforced with a metal net
+N - standard cut or in accordance with customer’s drawing
+6 - hardness from 55° to 65° Sh D / standard /
+8 - hardness above 75 ° D /very hard /
Sheeted friction linings of GC-BO type are produced only above 75 ° D and in manufacture versions depending on customer’s needs.
Examples of symbols:
GC – E + ZN6 - a lining reinforced with a net, chased, hardness
55° to 65° Sh D / standard /
GC - ES +8 - a lining with hardness above 75° Sh D /very hard /
GC – MK +Z – a net reinforced lining with standard hardness
By placing an order please specify a shape, dimensions and tolerances according to technical requirements for the needed type of lining and in correspondence to a customer's technical documentation.
