Hot sale PC45R-8 60-7 SWING MOTOR KOMATSU Hydraulic Pump Parts | Partsdic®

The PC45R-8 60-7 swing motor is designed for use in Komatsu's PC45R-8 60-7 excavator model.

This swing motor plays a crucial role in enabling the excavator's upper structure to rotate horizontally, allowing for precise positioning and digging operations. It is a high-performance component that must meet specific standards to ensure the excavator's efficiency and safety.

Key specifications of the PC45R-8 60-7 swing motor include its displacement, torque, and speed. The displacement refers to the volume of hydraulic fluid that the motor can deliver per revolution. It is usually measured in cubic centimeters (cc) or liters (L). Torque represents the motor's rotational force and is measured in Newton-meters (Nm). Speed denotes how fast the motor can rotate and is measured in revolutions per minute (RPM). These specifications are crucial for determining the motor's overall performance.

The hydraulic pump parts of the PC45R-8 60-7 swing motor consist of various components that work together to ensure the smooth and efficient operation of the motor. Some of the essential parts include:

Housing: The housing is the outer casing that encloses all the internal components of the swing motor, providing protection and support.

Cylinder Block: The cylinder block houses the pistons and swash plate mechanism. It plays a key role in converting hydraulic pressure into rotational motion.

Pistons: Pistons are reciprocating components within the cylinder block that move back and forth in response to hydraulic pressure changes. These movements create the rotational motion of the motor.

Swash Plate: The swash plate is an inclined disc that adjusts the angle of the pistons as they move, controlling the motor's displacement and speed.

Port Plate: The port plate contains various ports and passages that regulate the flow of hydraulic fluid into and out of the motor.

Bearings and Seals: Bearings ensure smooth rotation of the motor's internal components, while seals prevent hydraulic fluid from leaking.

Shaft: The motor's output shaft connects to the excavator's swing mechanism, transmitting rotational motion to the upper structure.

Control Valve: In some cases, a control valve may be included as part of the hydraulic pump system to regulate the flow and pressure of hydraulic fluid to the motor.
