🔧 SG025 Hydraulic Motor Components

Cylinder Block

• The main body in which the pistons move.
• Transmits hydraulic pressure to the pistons.

Pistons

• Convert hydraulic pressure into rotary motion.
• Typically consist of multiple pistons within the cylinder block (e.g., 9–12 pistons).

Valve Plate (Distribution Plate)

• Directs the flow of hydraulic fluid: sends pressurized fluid to the pistons and returns it to the reservoir.
• Critical for controlling the motor’s direction and speed.

Swash Plate / Rotor

• Moves the pistons to generate rotary motion.
• The tilt angle determines motor speed and torque.

End Cover / Bearings

• Encloses the motor and supports piston and rotor movement.
• Provides sealing and stability under high pressure.

Retainer / Shoes

• Guides the pistons over the swash plate.
• Ensures smooth and quiet piston movement.

📌 Summary

The SG025 hydraulic motor converts high-pressure hydraulic energy into rotary motion.

• Cylinder block + pistons + valve plate = core power generation mechanism
• Swash plate + end cover + retainer = motion direction and mechanical support

All of these components directly affect the performance and lifespan of the hydraulic motor.
