Miniature Metric Precision Ball Screws

Miniature Metric Precision Ball Screws

Miniature Metric Precision Ball Screws are an efficient and cost-effective solution in a small envelope, ideal for use in small spaces. Ball screw assemblies range from 4 to 14mm in diameter with leads from 1 to 20mm - all with standard lead accuracies of ±52µm/300mm. Miniature Rolled Ball Screws are ideal for laboratory, semiconductor, and medical applications.
