For the first time ever, Body-Solid. gps . This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings. Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity. The Linear Bearing will handle heavy and consistent use with calm, even-handed durability.
Smooth operation is the key.
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. Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity. 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.
