Shims (Part No.: 3115029702 3EA) – Precision Alignment Components for Hydraulic Rock Drills
Hydraulic rock drills are critical to mining, quarrying, and construction, where tight tolerances drive efficiency and equipment lifespan. Shims (Part No.: 3115029702 3EA) are essential spacing and alignment parts for these tools, and moreover, we engineer them to strict OEM specs for a seamless fit that eliminates misalignment, reduces wear, and sustains peak performance in harsh, high-vibration environments.
Core Functions
1. Micron-Level Spacing
These shims deliver precise gap control between drill pistons, valves, and gears, and therefore, they prevent metal-to-metal friction, seal leaks, and hydraulic system breakdowns even under heavy loads.
2. Vibration Dampening
Hydraulic rock drills generate intense shock during operation, and as a result, these shims act as a buffer to absorb vibration, reducing stress on internal systems and extending the service life of adjacent components like drill rods.
Durable Construction
1. Wear-Resistant Alloy Steel
We use premium alloy steel for these shims, and unlike low-carbon alternatives, this material resists warping and abrasion, retaining its shape despite exposure to rock dust and impact.
2. Corrosion-Resistant Heat Treatment
Every shim undergoes targeted heat treatment; additionally, this process boosts surface hardness and forms a protective oxide layer, shielding against rust and hydraulic fluid corrosion for long-lasting use.
Easy Installation
1. OEM-Grade Compatibility
The shims match top hydraulic rock drill specs exactly, so they ensure a drop-in fit with no on-site modifications and zero misalignment risks.
2. Tool-Free Replacement
Downtime equals lost revenue in drilling operations, and consequently, maintenance teams can swap worn shims in minutes without specialized tools, minimizing equipment downtime.
In summary, these shims maximize hydraulic rock drill uptime, cut maintenance costs, and protect your equipment investment.
