The. muscle building . 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. Simply lock the bar into position and add your weights. The Linear Bearing will handle heavy and consistent use with calm, even-handed durability.
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. 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. This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings. The Best Combination of Raw Power and Precision Design.
