Transport Ball Screws - The Transport Industrial ball screw range effectively converts high torque rotary input into precise high load linear movement for the more arduous applications. All transport ball screws can be delivered cut to length and if required, machined ready to fit into the required support bearing mounts. Utilising the recirculating ball bearing nut technology as the base of the product, the Industrial class ball screws encompass screw diameters from 12mm up to 80mm as standard with C7 accuracy. Leads of 1mm to 50mm are available through a large range of ball nut designs which in many cases utilise multiple ball circuits to achieve greater load capacities. Typically the Transport ball screws are rated for millions of mm’s of travel at the rated dynamic load. This is the load at which 90% of a group of identical ball screws will run without flaking for their lifetime. However, they will travel farther than this at lower limits.
