378-1879 463 mm OD Brake Friction Disc
Cat® Friction Disc (Brake)
Description
Cat powertrain components must withstand extremely high torque, high shock loads, and frequent directional changes. Cat designs components with these demands in mind, ultimately improving the performance of the powertrain over the life of the machine. Cat friction discs work with brake systems to provide the critical friction needed to slow, stop, or hold the machine stationary.
Features
- Three-way multiple parallel grooves optimize heat dissipation.
- Hardened steel core reduces spline wear.
- (68) tooth internal spline ensures OEM fit.
- OEM friction formulation maintains braking performance to certification standards.
Applications
Refer to your Operation and Maintenance Manual or contact MECHSC for more information.
