Superior performance for today’s most stringent positioning requirements.
Thomson has a wide range of internal return metric ball screw products, featuring four distinct product families — Miniature, Fineline, Thomson NEFF and Precision Plus. Each family is designed to meet unique application requirements.
Miniature Rolled Ball Screws
Miniature Rolled Ball Screw Assemblies are an efficient, cost-effective solution in a small envelope. Ball screw assemblies range from 4mm to 14mm in diameter, with standard lead accuracies of 52 microns/300mm. Compact ball nuts are available with body diameters as small as 11mm and overall lengths as short as 17mm. Miniature Rolled Ball Screws are ideal for laboratory, semiconductor, and medical applications.
FineLine Rolled Ball Screws
FineLine Rolled Ball Screw Assemblies are designed and manufactured to provide high level performance at an affordable price. Ball screws are manufactured using Thomson’s patented, German-engineered Precision Screw Forming (PSF) Technology, which provides high accuracy (23 mi-crons/300mm standard) with the manufacturing efficiency of rolled processes. Ball nuts are manufactured with one of two ball return systems (button or end return) made with reinforced steel, making them extremely durable and ideal for high speed, high load, and/or high temperature applications. Each nut comes standard with an integral plastic wiper to protect against chips or other debris. FineLine Rolled Ball Screws are ideal for machining centres, factory automation, packaging, and injection moulding applications.
Thomson NEFF Rolled Ball Screws
Neff Rolled Ball Screw Assemblies are available in a wide range of diameters, leads and nut styles — all designed to provide quiet, smooth running, efficient performance. Standard NEFF ball screws are rolled to an accuracy of 50 microns/300mm, with higher accuracies readily available upon request. Ball nuts include one of three unique ball return systems (depending on the diameter and lead of the screw used) providing perfect guidance, low wear, and smooth running performance. Ball nuts come standard with profiled rubber wipers to contain lubricant and help repel fine contaminants (dust, powders, etc). NEFF Rolled Ball Screws are ideal for wood working, water cutting, electronic assembly and medical applications.
Precision Plus Ground Ball Screws
Precision Plus Ground Ball Screw Assemblies are our highest precision product, with standard lead accuracies of 12 microns/300mm. These ball screw assemblies feature our FL-style ball nut, precisely preloaded to customer specifications. This unique nut design provides high repeatability and high stiffness for the most demanding ball screw applications. Each nut comes standard with an integral plastic wiper to protect against chips and other debris. Precision Plus Ground Ball Screws are ideal for applications requiring high repeatability and high stiffness (e.g., high precision machine tool).
