Seldén BBB Ball Bearing Blocks
Ball bearing blocks (BBB) should primarily be used when a smooth run of the rope is required, and the load is not particularly high. They provide low friction resistance for quick rotation of the sheave. Ball bearing blocks are always the ideal choice for moving blocks, such as for sheets, barber haulers, etc. Due to the nature of the ball bearing, where the balls rest in a groove within the bearing, the block can also handle lateral loads effectively without increasing rolling resistance.
