• High-Capacity, Long-Life: Each ball nut assembly of the Rockford preloaded unit has one
circuit of 3 1/2 turns of ball bearings. It will provide a load life expectancy of 50 million
inches of travel at an operating load of 400 pounds. The screw and nut assemblies are
made of hardened steel.
• Precision-Rolled Ball Screws: Lead accuracy is guaranteed to be within
.003 inches per foot accumulative. Lead charts for programming lead
error on n/c applications are available.
• Preloaded Ball Nuts: Each ball nut is preloaded to eliminate lost
motion. This system stiffness provides faster response from a
control command. This added stiffness also allows heavier cuts
and climb milling thus increasing productivity. The Rockford
preload is adjustable. This feature permits readjustment for wear
and reduces the need for repair or replacement at some time
in the future.
• Brush-Type Wipers: Brush-type wipers, at the ends of each
preloaded ball nut assembly prevents entry of dirt and
metal chips.
