:: Features

  • Bearings:
    • 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
  • Bushings:
    • 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
