Description
Additional information

MERIT pistons are manufactured as direct-fit, OEM-equivalent replacement components for the Rammer G100 hydraulic breaker. Each piston is precision-machined to meet or exceed original equipment performance standards, ensuring reliable operation, optimal energy transfer, and long service life in demanding demolition and quarry applications.

The piston is the primary energy-transmitting component of a hydraulic breaker. Once hydraulically charged, it delivers high-impact force to the tool (chisel), generating the power required to fracture rock, concrete, or other hard materials. Because breaker models vary in bore size, stroke length, and operating dynamics, MERIT pistons are engineered with model-specific dimensions, tolerances, and metallurgy to ensure precise fitment and consistent impact efficiency.

MERIT replacement parts are manufactured using high-grade alloy steels, advanced heat-treatment processes, and strict quality control to provide durability under extreme cyclic loads and high-pressure environments typical of hydraulic rock breaker operation.

MERIT Piston High Performance Replacement for Rammer G100

Material Specification: SAE 4340 Alloy Steel

This piston is manufactured from SAE 4340, a high-strength nickel-chromium-molybdenum alloy steel known for its exceptional toughness, fatigue resistance, and impact durability in heavy-duty applications.

SAE 4340 is specifically selected for hydraulic breaker pistons because it maintains structural integrity under extreme cyclic loading and high-energy impact conditions. The material provides an optimal balance of strength and ductility, minimizing the risk of brittle failure during continuous demolition operations.

Key Material Characteristics

High tensile strength with excellent core toughness after heat treatment
Outstanding fatigue resistance under repeated impact loading
Superior hardenability, ensuring uniform mechanical properties throughout the cross-section
Excellent resistance to shock, wear, and stress-related cracking
Reliable performance in high-pressure hydraulic environments

Heat Treatment Process
The piston is quenched and tempered to achieve a controlled hardness profile, ensuring:

A tough, crack-resistant core for effective energy absorption
A wear-resistant surface to extend operational service life
Dimensional stability during high-frequency impact cycles

Application Advantage
The use of SAE 4340 enables consistent energy transfer, extended service life, and dependable performance aligned with OEM-equivalent requirements for hydraulic rock breaker systems.

This material is ideal for components subjected to severe mechanical stress, where durability, resilience, and operational reliability are critical.

Extended Compatibility

MERIT supplies OEM-equivalent replacement parts compatible with a wide range of hydraulic rock breaker brands, including:

Epiroc, Rammer, Sandvik, Atlas Copco, Krupp, Furukawa, Montabert, DNB, and NPK.
