Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity. It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter. The Best Combination of Raw Power and Precision Design. The Linear Bearing will handle heavy and consistent use with calm, even-handed durability. It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter.
Smooth operation is the key.
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. This reduces friction resistance, consumes less energy and attains a far lower.
