Common Causes of Bearing Failure and How HBT Bearings Help Prevent Them

Bearings are vital components in almost every machine. From large industrial gearboxes and conveyor systems to electric motors and pumps, bearings keep rotating parts aligned, reduce friction, and ensure long-term reliability. However, even the best machinery can come to a grinding halt if its bearings fail unexpectedly.

Understanding what causes bearing failure — and how to prevent it — is essential for plant managers, maintenance teams, and machine operators. In this blog, we’ll explore the most common reasons bearings fail and how HBT Bearings, distributed by SSN Enterprise, are engineered to prevent these costly issues.

Let’s dive in.

Why Bearing Failure Is a Big Deal

When a bearing fails, the consequences can be serious:

• Unplanned downtime

• Costly repairs

• Lost production hours

• Damage to adjacent components

• Increased labor and maintenance costs

Most of these failures are avoidable — if you understand the warning signs and use quality bearings designed for the job.

1. Lubrication Issues

🛠 Cause: Insufficient, excessive, or improper lubrication is the number one reason for bearing failure. Without proper lubrication, friction increases, causing excessive wear and overheating.

🛡 How HBT Bearings Help:

• HBT offers pre-lubricated and sealed bearings for applications where regular maintenance is difficult.

• Their bearing surfaces are finely polished to reduce friction.

• Advanced seal designs prevent lubricant leakage and contamination entry.

✅ Pro Tip: Use the recommended lubricant grade and re-lubricate at proper intervals to extend bearing life.

2. Contamination

🛠 Cause: Dirt, dust, moisture, or other foreign particles can enter the bearing and cause pitting, corrosion, and early failure.

🛡 How HBT Bearings Help:

• Sealed and shielded bearings are designed to operate in dirty or wet environments.

• Options available with corrosion-resistant coatings and materials.

✅ Pro Tip: Always store bearings in clean, dry areas and use clean tools during installation.

3. Improper Installation

🛠 Cause: Using incorrect tools, applying uneven force, or misaligning components can damage the bearing during installation.

🛡 How HBT Bearings Help:

• Manufactured with tight dimensional tolerances for easy and accurate fitment.

• SSN Enterprise provides guidance and support for correct installation methods.

✅ Pro Tip: Use proper bearing pullers, press tools, and follow OEM torque recommendations during installation.

4. Misalignment

🛠 Cause: When shafts or housings are not properly aligned, it can create uneven load distribution, leading to premature wear.

🛡 How HBT Bearings Help:

• Self-aligning ball bearings and spherical roller bearings compensate for shaft misalignment.

• Available in both standard and custom fitments.

✅ Pro Tip: Inspect shafts, housings, and mounting points before installing new bearings.

5. Overloading

🛠 Cause: Bearings subjected to loads beyond their capacity can deform or fracture under pressure.

🛡 How HBT Bearings Help:

• HBT's high-load-bearing designs (like taper roller and cylindrical roller bearings) are ideal for heavy-duty industrial applications.

• Designed with superior steel and heat-treatment processes to handle extreme stress.

✅ Pro Tip: Choose bearings based on accurate load calculations, not just dimensions.

6. Electrical Damage

🛠 Cause: Electrical currents (often from motors or VFDs) can pass through the bearing, causing fluting and surface damage.

🛡 How HBT Bearings Help:

• Insulated bearing options are available for electrical environments.

• Bearings for electric motors are manufactured to reduce conductivity and improve resistance.

✅ Pro Tip: Use grounding brushes and insulated bearings where high voltage or VFDs are used.

7. Fatigue and Overuse

🛠 Cause: Like any component, bearings wear out over time due to rolling fatigue, especially in high-speed, high-load applications.

🛡 How HBT Bearings Help:

• Manufactured using clean, high-quality steel with enhanced fatigue life.

• Tested rigorously for thousands of operational hours.

✅ Pro Tip: Use predictive maintenance tools to monitor vibration and temperature trends.
