385-3940 Clutch Friction Disc
Cat® special steel friction disc for planetary transmissions, pressure angle of 20 degrees
Description
Cat powertrain components must withstand extremely high torque, high shock loads, and frequent direction changes and shifts. Cat designs and manufactures transmission and final drive components with these demands in mind, ultimately improving powertrain durability and performance over the life of the machine. Cat friction discs work with the brake system to provide the critical friction needed to slow, stop, or hold the machine stationary.
Features
- Full waffle-pattern grooves optimize heat dissipation.
- Hardened steel core reduces spline wear.
- (46)-tooth external spline ensures an accurate OEM fit.
- OEM friction formulation maintains braking performance to certification standards.
