Selden Ball Bearing Blocks

Ball bearing blocks (BBB) are used where the loads are more moderate and dynamic. The ball bearing provide for good sheave rotation with the lowest possible friction. Available in 20,30,40, and 60mm sheave diameters

  • Stainless steel ball bearing races
  • Stainless steel ball bearings and acetal sheaves for best bearing strength
  • Acetal bearing cages to prevent ball to ball friction and reduce weight
  • glass fiber reinforced composite
