2/B73 Banded V-Belt (2-Rib, B Section)

Reliable, high grip 2/B73 banded V-belt designed for drives that need extra stability and vibration resistance. Two B-section belts are permanently joined by a durable backing to keep ribs running in perfect parallel—ideal for shock loads, pulsating drives, and applications where single belts twist or flip.

Key Features

  • Banded 2-rib design minimizes belt whip and misalignment issues.
  • Classic B profile for easy drop in replacement on standard B section sheaves.
  • Oil & heat resistant wrapped construction for long service life.
  • Low maintenance: matched ribs are factory joined—no field matching required.

Common Applications

  • Fans & blowers, pumps, compressors
  • Conveyors, grain & agricultural equipment
  • Industrial machinery where multi-belt sets are specified
