The Best Combination of Raw Power and Precision Design. The Best Combination of Raw Power and Precision Design. 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. The no-impact nature means there is less stress placed on the joints. 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.
Smooth operation is the key.
Simply lock the bar into position and add your weights. Simply lock the bar into position and add your weights. This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings. 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.
