This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings. Smooth operation is the key. 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. Simply lock the bar into position and add your weights.
