Product Specification

Rammer Classic Series Bushing Set for Hydraulic Breaker Chisel Guidance and Wear Protection

The Rammer Classic Series Bushing Set includes Inner Bush and Outer Bush, which are essential wear components installed in Rammer Classic Series hydraulic breakers. These bushings guide the movement of the chisel, maintain proper tool alignment, and protect the breaker front head from excessive wear during high-impact operation.

The hydraulic breaker bushing system plays an important role in transferring impact energy efficiently. During operation, the chisel moves repeatedly at high speed while experiencing impact force, side loading, and friction. Without a reliable bushing system, the tool may become unstable, causing uneven wear, reduced breaking efficiency, and potential damage to the front head.

Our Rammer Classic Series Inner Bush and Outer Bush are manufactured from wear-resistant alloy materials with precision machining and professional heat treatment. The products are designed according to OEM-compatible specifications, ensuring accurate fitting, excellent wear resistance, and extended service life.

Suitable for hydraulic breaker repair, maintenance, and rebuilding, our replacement bushing sets provide a dependable solution for distributors, repair workshops, construction contractors, and equipment users worldwide.
