Simply lock the bar into position and add your weights. 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.
Smooth operation is the key.
The no-impact nature means there is less stress placed on the joints. 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. The Linear Bearing will handle heavy and consistent use with calm, even-handed durability.
