Columbus Supply

:: Features

• Bushing:
  • Spreads the load over a larger area of the axle, sliding the load around the pulley
  • Greater transfer and very little wear and longer life
  • Greater area in contact results in increased friction, decreasing efficiency
• Bearing:
  • Decrease the amount of surface area in contact with the axle, which creats a more efficient transfer
  • By rolling the load around the axle, load on the transfer point is increased, which results in faster wear, shortening the life of the pulley
