Description

self-aligning bearing is a type of rolling-element bearing designed to automatically compensate for misalignment between the shaft and the housing. This misalignment can occur due to mounting errors, shaft deflection, or thermal expansion.

Key Features of Self-Aligning Bearings:

  1. Spherical Design – The inner ring has two raceways, while the outer ring has a spherical raceway, allowing the inner ring to pivot slightly.

  2. Automatic Alignment – Can adjust to angular misalignment (typically 2-3 degrees, some up to 5 degrees), reducing stress and wear.

  3. Reduced Friction & Longer Life – Minimizes edge loading, improving performance in misaligned conditions.

  4. Common Types:

    • Self-Aligning Ball Bearings (e.g., 1200 & 1300 series) – Good for moderate loads and misalignment.

    • Spherical Roller Bearings – Handle heavy radial and axial loads with higher misalignment tolerance.

Applications:

  • Industrial machinery with shaft deflection (e.g., conveyors, fans, pumps).

  • Agricultural equipment.

  • Paper and steel mill machinery.

  • Applications where precise alignment is difficult to maintain.

Advantages:

✔ Reduces wear from misalignment.
✔ Low maintenance.
✔ Handles dynamic misalignment (e.g., from load changes).

Disadvantages:

✖ Slightly higher cost than standard bearings.
✖ May have slightly lower load capacity compared to non-aligning bearings of the same size.
