Industrial Class Ball Screws

Industrial ball screws effectively convert high torque rotary input into precise high load linear movement. All industrial specified ball screws can be delivered cut to length and when required, machined ready to fit into the required support bearing mounts.

Utilising proven 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. In many cases multiple ball circuits, per ball nut, are employed to achieve greater load capacities making the product suitable for many types of heavy duty application. As the name suggests, the range is aimed at the more industrial type application with dynamic load capacities ranging from 900 to 13449 kgf. Whatever the load, it will be delivered with both high efficiency and low drive torque. Stocked screw lengths of up to 4500mm are available up to 32mm diameter and screw lengths up to 5600mm long for screws above 40mm in diameter.

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. These load-life relationships are analogous to the B10 rating common in the ball bearing industry. The relationship of load to life is an inverse cube relation. For example, by reducing the customers load by half would increase the life by eight times. (Conversely doubling the load would decrease life by 1/8).

ABSSAC has well over three decades of product ball screw product placement knowledge which is employed to ensure correct specification.
