20 years of experience in hydraulic cylinder manufacturers.
MPM cylinders are mainly used in:
Hydraulic Cylinder
Buffer Cylinder for excavator and backhoe loader
Description
Working principle
As the piston nears the end of its stroke, the main oil return passage is blocked. Hydraulic oil is then forced to discharge through tiny orifices and clearances, creating back pressure for damping. This gradually slows down and brakes the piston movement.

Core Functions
Deceleration at stroke ends, shock absorption, stable operation, noise reduction, and protection for cylinders and seals.

1.Anti-collision
Prevent rigid contact between the piston/rod and cylinder head/end cap. This avoids cylinder barrel deformation, piston rod bending and seal failure.

2.Hydraulic shock suppression
Eliminate extreme pressure spikes (up to 3–5 times the system pressure) at stroke ends. It protects hydraulic pumps, valves and pipelines, and relieves water hammer vibration.

3.Smooth operation
Prevent shaking of buckets and working arms, and improve the stability of combined movements.

4.Extended service life & noise control
Minimize impact wear and abnormal noise. It prolongs the service life of the cylinder and enhances operator comfort in the cab.

Application：
1.Excavator:
End cushioning slows down the boom and bucket at stroke ends, preventing the bucket from hitting the ground.

2.Backhoe loader:
It ensures smooth movement of the digging arm and bucket. Operation stays steady without harsh shaking, for reliable lifting and precise work.

3.Truck crane:
The cushioning function for outriggers softens the landing impact and avoids sudden jolts to the vehicle body.
