Wholesale Buffer Cylinder for excavator and backhoe loader Supplier, Manufacturer
Product Description
Product Description
Prevent rigid contact between the piston/rod and cylinder head/end cap. This avoids cylinder barrel deformation, piston rod bending and seal failure.
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.
Prevent shaking of buckets and working arms, and improve the stability of combined movements.
Minimize impact wear and abnormal noise. It prolongs the service life of the cylinder and enhances operator comfort in the cab.

Industrial Applications
End cushioning slows down the boom and bucket at stroke ends, preventing the bucket from hitting the ground.
It ensures smooth movement of the digging arm and bucket. Operation stays steady without harsh shaking, for reliable lifting and precise work.
The cushioning function for outriggers softens the landing impact and avoids sudden jolts to the vehicle body.
Minimize impact wear and abnormal noise. It prolongs the service life of the cylinder and enhances operator comfort in the cab.

Frequently Asked Questions (FAQ)
When the piston approaches the stroke limit, the primary oil return path closes. Hydraulic fluid is redirected through precise damping orifices, establishing controlled backpressure that decelerates the piston smoothly and prevents metal-to-metal collision.
Yes. Custom design is a primary service of MPM. We engineer cylinders around your target bore, rod diameter, stroke, installation distance, mounting configuration, and required operating pressure.
Cylinders undergo thorough surface preparation including sandblasting, followed by a multi-tier protective paint system consisting of primer paint, intermediate layer, and durable finish coat to withstand severe environmental exposure.
Heavy equipment enduring high inertia and frequent cycle stops—such as excavators, truck cranes, backhoe loaders, and underground mining equipment—benefit significantly through reduced mechanical wear and suppressed hydraulic pressure spikes.
Every cylinder undergoes rigorous pressure and structural validation. Units rated for a working pressure of 20MPa are tested up to 30MPa to guarantee safety margins, zero internal or external bypass, and full structural integrity.
