Proper Lubrication of Pneumatic Hammers

Pneumatic hammers are essential tools in the construction, mining, and drilling industries. Their proper functioning largely depends on adequate lubrication, as this reduces wear, improves efficiency, and prolongs the equipment's lifespan.

In this article, we will explain the importance of lubrication, the recommended types of lubricants, the application frequency, and the common mistakes to avoid to ensure your pneumatic hammers operate at peak performance.

Proper lubrication helps keep pneumatic hammers in optimal condition, ensuring greater productivity and lower maintenance costs.

These oils are specifically formulated to reduce friction and protect against corrosion. Their main characteristics include:
🔹 High thermal resistance to withstand extreme temperatures.
🔹 Anti-wear properties to prolong the hammer's lifespan.
🔹 Low residue formation to avoid blockages in valves and air ducts.

📌 Recommendation: Use oils with a viscosity of ISO VG 32 or 46, depending on the manufacturer.

In some cases, greases are used on external components of the hammer, such as the impact mechanism and connections. These greases should be:
✅ Water-resistant and resistant to dust contamination.
✅ With a high dropping point to prevent them from liquefying with temperature.

🔹 Step 1: Check the oil level in the lubrication system.
🔹 Step 2: Apply between 3 and 5 drops of pneumatic oil at the air inlet before starting the hammer.
🔹 Step 3: Start the hammer for a few seconds to distribute the lubricant internally.

🔹 Inspect the condition of the lubricant in the connections and cylinders.
🔹 Check for accumulation of residues or dirt in the air ducts.
🔹 Apply grease to external moving parts (if necessary).

❌ Using inappropriate oils: Never use motor or hydraulic oils, as they can generate residues and damage the equipment.
❌ Applying too much oil: Excess can accumulate and affect the hammer's performance.
❌ Not lubricating regularly: Lack of lubrication leads to premature wear and equipment failures.

The proper lubrication of pneumatic hammers is essential to ensure their efficiency, prolong their lifespan, and reduce maintenance costs. By following these tips and using the appropriate lubricants, you can maximize the performance of your tools and avoid unexpected failures.
