Product Specification

Rammer S Series Bushing Set for Hydraulic Breaker Tool Protection

The Rammer S Series Bushing Set includes Inner Bush and Outer Bush, which are essential wear components installed in hydraulic breakers to support the working tool, maintain tool alignment, and protect the breaker housing from excessive wear.

During hydraulic breaker operation, the chisel is exposed to continuous high-frequency impacts and side forces. The inner and outer bushes provide a stable guiding surface for the tool, reducing friction between the chisel and breaker body while improving impact efficiency and operational stability.

Our Rammer S Series Inner Bush and Outer Bush are manufactured from wear-resistant alloy steel with precision machining and advanced heat treatment technology. Each bushing is produced according to OEM specifications to achieve accurate dimensions, excellent hardness, and long service life under demanding working conditions.

Designed for Rammer S Series hydraulic breakers, these replacement bushings provide reliable performance for construction companies, equipment distributors, repair workshops, and aftermarket service providers.
