151 779 68 REAR BUSHING

151 779 68 REAR BUSHING SANDVIK – Precision Fit for Superior Rock Drilling Performance

The 151 779 68 REAR BUSHING SANDVIK is a crucial component within the hammer assembly of Sandvik rock drills, designed to deliver peak mechanical support and performance reliability. Engineered with hardened alloy steel and a copper-alloy inner lining, this rear bushing acts as a bearing interface that minimizes friction and wear between moving parts during heavy-duty operations. Whether you’re tackling mining, tunneling, or quarrying applications, this part plays a vital role in optimizing drill longevity and efficiency.

At its core, the 151 779 68 REAR BUSHING SANDVIK functions as the rear guiding surface for the piston and shank components. It absorbs the intense repetitive impacts during rock penetration, dampens vibration, and ensures proper axial alignment of the internal striking mechanism. The combination of a steel outer shell with a precision-machined bronze or brass sleeve gives this part both durability and elasticity—allowing it to maintain performance even under high-pressure shock loads.

Key Features of 151 779 68 REAR BUSHING SANDVIK:

• High-Grade Construction: Manufactured from corrosion-resistant alloy steel, providing robust protection against abrasive dust and high-impact forces.

• Dual-Material Design: Interior bronze or copper-alloy bushing offers excellent anti-friction properties for smoother piston reciprocation.

• Precision Fit: Designed to fit seamlessly into OEM hammer housings for maximum operational integrity.

• Extended Service Life: Built to reduce heat generation and component wear, prolonging the lifespan of adjacent parts.

• Custom Machined: Ensures an exact tolerance match for Sandvik rock drills, improving energy transfer and striking accuracy.

Why the 151 779 68 REAR BUSHING SANDVIK Matters

A failing or worn rear bushing can introduce misalignment in the rock drill’s impact system, leading to energy loss, irregular percussion, and even catastrophic damage to pistons or shank adapters. The 151 779 68 REAR BUSHING SANDVIK is manufactured with strict dimensional tolerances and tested for hardness, ensuring that it upholds Sandvik’s standards for demanding underground and surface drilling environments.

This component is responsible for centering and protecting your rock drill’s high-value internals. Its job may seem modest, but it’s critical in absorbing axial loads while also creating a lubricated interface between reciprocating components. Over time, sub-par bushings create chatter, compromise energy efficiency, and reduce the life expectancy of the overall system. That’s why replacing them with OEM-standard components like this bushing from 3GEN Export ensures lasting reliability.
