Precision, reliability, quality, value for money, and on-time delivery are all at the core of the ball screw ranges provided by SCREW-TECH. With existing customers reporting a 98% satisfaction rate in a recent survey, they take pride in their exceptional track record. Precision ball screws with outside diameters ranging from 4mm to 16mm and a variety of leads per diameter are typically offered. The transport ball screws have diameters ranging from 10mm to 80mm, catering to industrial applications with dynamic load capacities from 900 to 13449 kgf, ensuring accuracy and efficiency without sacrificing high drive torque. Stocked screw lengths for transport ball screws reach up to 4500mm for diameters up to 32mm and up to 5600mm for diameters over 40mm. Additionally, SCREW-TECH has the capability to customize application-specific ball nuts, reducing the number of parts needed with their linear design. All ball screws provided by SCREW-TECH can be delivered with the journal ends machined to print, ensuring easy fitting into suitable bearings or applications. This not only eliminates potential scrap rates for customers but also guarantees that the assemblies meet the required accuracy tolerances. To simplify the selection process, SCREW-TECH categorizes the ball screw ranges into distinct categories based on specific applications.Life Expectancy SCREW-TECH is frequently asked about the life expectancy of the ball screw products it supplies for various applications. While it can sometimes be challenging to accurately calculate due to potential changes in application parameters over time, it is still achievable. During a recent design consultation with one of our packaging machinery customers, a new series of machines was being developed with remarkably long mean time between services (MTBS). The unique selling point of these machines was their reliability and extended service intervals. The ball screw chosen for use would play a crucial role in providing the primary linear movement required in the design, making it a critical component for ensuring performance. Typically, our ball screws are designed to withstand millions of millimeters of travel at the rated dynamic load. This load represents the threshold at which 90% of a group of identical ball screws will operate without undergoing flaking throughout their lifespan. Moreover, these ball screws can travel even farther beyond this limit at lower loads. The relationship between load and life span follows an inverse cube relation, much like the B10 rating system commonly used in the ball bearing industry. For instance, cutting the customer's load in half would result in an eightfold increase in the ball screw's lifespan. Conversely, doubling the load would reduce the lifespan by one-eighth.
