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