Cat® Long Shaft is a metal bar that join parts of a machine together, enabling power and movement to be passed from one part to another. The shafts comprises a U joint to transmit motion in different axis of rotation. Cat® Axle components must endure incredible torque, high impact loads, and frequent direction and gear changes. Cat® components are designed and manufactured to meet these types of demands. The result is a drive train that lasts longer and works harder over the life of the machine. Cat® Parts are manufactured to precise specifications and are built for durability, reliability, productivity, less environmental impact and reuse. Durable Cat® parts protect sensitive components from impact and abrasion in the tough working conditions that Cat® machines experience.External Involute Spline DataNumber of Teeth : 26Module : 1.25Pressure Angle : 30Application:Cat® Long Shaft is used to transmit motion in front axle of Cat® Machines.
