ABSSAC offers an Industrial ball screw range, termed the Transport range, that effectively converts high torque rotary input into precise high load linear movement. The Transport ball screw ranges 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. In many cases multiple ball circuits, per ball nut, are employed to achieve greater load capacities making the product suitable for many types of application.
As the name suggests, the range is aimed at the more industrial type application with dynamic load capacities from 900 to 13449 kgf being catered for. 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.
ABSSAC is often asked about the life expectancy of the ball screw products it supplies within applications. Whilst this can sometimes be a difficult thing to accurately calculate, as parameters within an application can change during its life, it can nevertheless be achieved. During a recent design brief with one of our packaging machinery customers, a new range of machines were being designed with exceptionally long MTBS. (mean time between service). In fact, the machines unique selling point was to be its reliability and long service intervals. The ball screw to be used would also provide the primary linear movement required within the design, so was a critical part of the design guarantee.
Typically our 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). Armed with this information ABSSAC’s customer then made every attempt to reduce the load within the design, which after a great deal of design change was finally achieved. The end result was a ball screw assembly with the life expectancy required by the customer.

Our machining capability gives you a high journal concentricity product and can be applied to all screws regardless of diameter. Let us work together to reduce your scrap rates and supply ball solutions that fit your application every time. We can work directly from your dimensional drawings or if they do not exist, why not supply us with a physical sample for us to copy. Although all types of end machine detail can be supplied we offer a very cost effective basic end journal machining that fits our range of support bearings (see example diagrams below)
