Friction lining LR356 - Technical data  |  Friction material: Brake lining - clutch facing

  Material Description

Asbestos-free, moulded, homogeneous friction lining, very hard, metal-free, colour reddish brown.
Base materials: Various shingled fibres, synthetic resin, highly compressed.
High level of friction coefficient, stable friction behaviour, very good mechanical properties.
Suitable for extremely demanding applications, such as highly stressed clutches and torque limiters for agricultural
and construction machinery, pads for presses, punches, forging machines, annular gears.
Very good bonding and riveting behaviour. Resistant to oil and gasoline.
If used under oily conditions or with gasoline (test required) mind the reduced friction factor.

* The data are for your guidance only and do not render the application-specific testing unnecessary.
Accordingly, we cannot guarantee their accuracy as there are lots of possible applications.
The operating values are maximum values which must not occur simultaneously. Observe safety values!
The temporarily permissible temperature - measured on the pulley - may occur for only a few seconds.
For special applications we recommend you to consult our application engineers.
