Custom Lead Screw Machining

Nanotec provides precision machining services for lead screws, offering a wide range of customization options to meet specific application requirements.

Overview of Nanotec Lead Screw Machining Services

Nanotec offers custom machining for lead screws, supporting various screw end configurations:

Screw end with chamfer
Width across flats
Metric ISO thread
Non-locating bearing seat
Locating bearing seat and press fit
Smooth screw ends

For applications requiring enhanced service life and performance, lead screws are available with an optional DLC (Diamond-Like Carbon) coating. This protective coating improves friction characteristics, potentially increasing the service life of mating nuts by approximately 100%.

General Lead Screw Selection

Customers can select lead screws based on thread code, screw end types, desired screw length (ranging from 50 to 500 mm), and the required number of pieces. Detailed specifications and dimensions are provided on the following pages.

Important Notes

The standard tolerance for screw length is +3/+0 mm.
For lead screws in stock, delivery time is typically one week for 1-24 pieces and approximately two weeks for 25 or more pieces. Stock availability can be checked on the Nanotec website.
For larger quantities or custom modifications, please contact the Nanotec sales department at info@us.nanotec.com.
Deburring creates a chamfer with an undefined angle and size, ensuring optimal screw entry and reducing the risk of injuries. If no specific selection is made, screws will be deburred at no additional processing cost.
