The Linear Bearing will handle heavy and consistent use with calm, even-handed durability. 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. Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity. Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity.
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. It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter. It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter. The no-impact nature means there is less stress placed on the joints.
