For the first. strength . Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity. Simply lock the bar into position and add your weights.
Smooth operation is the key.
Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity. The no-impact nature means there is less stress placed on the joints. This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings. The Best Combination of Raw Power and Precision Design.
