MSB MS Series Hydraulic Breaker Front Head / Back Head for Chisel Support and Tool Guidance

The MSB MS Series Hydraulic Breaker Cylinder is a core structural and hydraulic component designed for MSB MS Series hydraulic breakers. Also known as the middle cylinder, it is the main working chamber where the piston moves under hydraulic pressure to generate impact energy.

The cylinder plays a critical role in hydraulic breaker operation by guiding piston movement, maintaining hydraulic pressure, and ensuring efficient energy conversion. During continuous breaking operations, the cylinder is exposed to high hydraulic pressure, repeated impact forces, and friction between the piston and inner surface. Therefore, cylinder material strength, machining accuracy, and surface treatment directly affect breaker performance and service life.

Our MSB MS Series Hydraulic Breaker Cylinder is manufactured from high-strength alloy steel with precision machining and professional heat treatment. The inner surface is processed with strict dimensional control to ensure smooth piston movement, proper sealing performance, and stable impact output.

Produced according to OEM-compatible specifications, our replacement cylinders provide a reliable solution for hydraulic breaker repair, rebuilding, and maintenance. They are widely used by distributors, repair workshops, contractors, and equipment owners worldwide.
