Precision ball screws

Kuroda Jena Tec is a renowned developer and manufacturer of grinded, whirled and rolled ball screws with nominal diameters between 5 mm and 100 mm.

Kuroda Jena Tec manufactures versions with 2-point contact using lead offset or double nut technology, as well as single nuts with 4-point contact in various precision classes. Whether individual components or large quantities, we manufacture according to your requirements and your individual drawing in accordance with JIS or DIN standards DIN 69051 or DIN 3408. With the special JT+ profile on offer, the torque drop is reduced to a minimum when rotation is reversed. Special requests, such as a soft flange for your own finishing, are checked individually.

In addition, the KURODA Group has access to international stocks.
