Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity. Smooth operation is the key. Simply lock the bar into position and add your weights. Utilizing a double circuit linear motion ball bearing system, the load is supported by several lines of balls inside return circuits which infinitely circulate com one side of the retainer to the other. It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter.
