Friction lining LR225 - Technical data | Friction material: Brake lining -

  Material Description

Asbestos-free, rolled material rolls, semi-flexible, containing metal, colour dark grey.
Base materials: Synthetic resin / caoutchouc, reinforced with synthetic fibres, cuttings, fillers.
Medium level of friction coefficient, medium temperature range, high repetitive accuracy.
Low noise level, punchable. Also available in the form of sheets.
General brake manufacture, drum brakes and band brakes, hoisting gears, elevators etc.
Very good bonding behaviour. Not suitable under oily conditions. Sintering under temperature influence.

* 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.
