Understanding Bearing Failure: Causes, Prevention, and the HBT Bearings Advantage

Bearings are the unsung heroes of every rotating machine — enabling motion, reducing friction, and carrying loads efficiently. But like all mechanical components, bearings can fail. And when they do, the cost can be enormous: production downtime, equipment damage, labor costs, and missed delivery deadlines.

That’s why understanding the root causes of bearing failure and taking steps to prevent them is critical for any industrial operation. At HBT Bearings, our engineering focus goes beyond performance — we help industries avoid breakdowns before they happen. With our trusted partner SSN Enterprise managing distribution across India, HBT Bearings deliver reliability that your operation can count on.

In this article, we’ll explore the main causes of bearing failure, how to prevent them, and how HBT Bearings is redefining durability in challenging industrial environments.

Common Causes of Bearing Failure

According to industry studies, over 90% of bearing failures are due to avoidable causes. Here’s what to watch for:

🧴 1. Lubrication Failure

• Inadequate or incorrect lubricant

• Contaminated grease

• Over- or under-lubrication

Symptoms: Excessive heat, noise, vibration HBT Solution: Pre-lubricated sealed bearings, optimized grease retention

🧹 2. Contamination

• Dust, dirt, moisture, or chemical ingress

• Poor seals or improper handling

Symptoms: Scoring on raceways, noise, early wear HBT Solution: Sealed and shielded designs, precision seal technology

⚙️ 3. Misalignment

• Shaft misalignment during installation

• Bent shafts or improper housing fit

Symptoms: Uneven wear, reduced performance HBT Solution: Self-aligning spherical and pillow block bearings

🔧 4. Improper Mounting

• Use of hammer, incorrect tools

• Forcing bearing onto shaft or into housing

Symptoms: Cracked races, deformed components HBT Solution: Technical support, guides, and standardized fits

🧊 5. Overloading

• Load exceeds bearing capacity

• Shock loads or vibrations beyond spec

Symptoms: Flaking, spalling, noise HBT Solution: Bearings engineered for high-load and impact resistance

📉 6. Fatigue & Material Defects

• Subpar materials or surface imperfections

• Low-quality manufacturing processes

Symptoms: Surface pitting, cracks, premature failure HBT Solution: High-grade steel, ISO-certified manufacturing, heat treatment

Prevention Tips: Extend the Life of Your Bearings

Here’s how to reduce the risk of failure:

• Store bearings in a clean, dry, sealed environment

• Use proper tools and techniques during installation

• Apply the right type and amount of lubricant

• Perform regular inspections (temperature, noise, vibration)

• Choose the correct bearing type for each application

• Always use authentic, high-quality bearings
