The Linear Bearing will handle heavy and consistent use with calm, even-handed durability. 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. It's superior to a free weight machine because it's safer for muscles and joints and can be used without a spotter. Ultrasonically tested, recirculating ball bearings offer smooth, straight-line accuracy with exceptional load capacity.
Smooth operation is the key.
