FRICTION and rubber products

Brake Pads

Escorts Brake Pad is an organic Non Asbestos composite brake pad for railway application. It is a rigid cold process moulded in dark brown color having synthetic, minerals & organic fibers with highly thermally stable “Novalac” phenolic powder resin as a binder in composition matrix to meet the strength & performance in terms of friction & wear properties.

This product meets the requirements of UIC specification on the Dynamometer.

BRAKE DISCS

Brake Disc is used in LHB Coaches of Indian Railways. It is mounted on the axle. When train needs to be stopped or decelerated, pressure is applied on the Brake Disc through Brake Pads on either side of the Brake Disc.

SALIENT FEATURES

  • First in India by an Indian manufacturer.
  • It is self-ventilated so no additional requirement for cooling of Brake Disc.
  • The Disc Assembly is press fitted to the Axle.
  • The Hub of the disc facilitates pressurized liquid assisted assembly and disassembly.
  • Speed upto 160Km/hr.
  • Brake Disc consists of friction ring with cooling ribs. The friction ring is casted as a single piece followed by its machining on required surfaces
  • The friction ring of brake disc has a groove around its outside circumference to indicate the condemning limit and when they have to be exchanged.
  • Suitable for axle load up to 16 tons.
