Chapter 2: Types of Bearing Wear
To develop an effective maintenance strategy and improve equipment reliability, it's essential to understand the various types of bearing wear that occur during operation. Each type of wear has unique causes and visual symptoms, which can help with early detection and corrective action.
1. Abrasive Wear
Abrasive wear occurs when hard particles or contaminants enter the bearing and cause grooves, scratches, or scoring on the raceways and rolling elements. It is often caused by dirty lubricants, inadequate sealing, or improper handling during installation.
Indicators:
Linear scratches along the rolling path
Increased noise and vibration
Surface dullness
DSBR’s Advantage: Our bearings are sealed with advanced multi-lip seals to block contaminants and are packaged with clean-room standards to prevent abrasive wear from the start.
2. Adhesive Wear (Scuffing or Galling)
This type of wear is caused by metal-to-metal contact when lubrication fails, resulting in localized welding and tearing of surfaces. It's common in high-speed applications or where misalignment occurs.
Indicators:
Smearing or torn metal on the contact surfaces
Abnormal operating temperature
Sharp increase in friction
DSBR’s Advantage: Our precision ground surfaces and optimized preload ensure minimal contact stress and smoother rotation under high loads.
3. Surface Fatigue (Pitting or Spalling)
Fatigue wear occurs due to repeated stress cycles leading to micro-cracks that develop into pits or flakes. This is typical in long-service bearings under heavy loads.
Indicators:
Flaking or pitting on raceways or rolling elements
Irregular noise and vibration
Gradual performance decline
DSBR’s Advantage: Heat-treated high carbon chromium steel and surface hardening (HRC 60–65) give DSBR bearings superior resistance to fatigue-related failure.
4. Corrosive Wear
Corrosive wear is a result of chemical reactions, usually caused by exposure to moisture, acids, or incompatible lubricants. It weakens the surface structure and can lead to premature failure.
Indicators:
Rust, discoloration, or etching
Uneven surface damage
Reduction in load capacity
DSBR’s Advantage: With specialized anti-corrosion coatings and rust-resistant packaging, DSBR bearings maintain integrity even in humid or chemically active environments.
By identifying the type of wear, maintenance teams can better predict failures and take proactive steps to reduce downtime. In the next chapter, we’ll analyze the root causes of bearing wear and how to detect them early.
