Frequently Asked Questions
Ground ball screws offer higher accuracy, smoother motion and longer life, ideal for precision machine tools and semiconductor equipment. Rolled ball screws are more cost-effective for general automation. Our Ball Screws range covers both types with accuracy classes from C0 to C10, so we can match the right grade to your application.
The Nut-Rotating Ball Screw R2 Series is available in accuracy classes from C0 to C10 and a wide choice of leads from 1 mm to 40 mm. Tell us your positioning accuracy and speed requirements, and our engineers will recommend the optimal lead and accuracy grade.
The maximum speed is limited by the critical speed, which depends on the screw diameter, unsupported length and mounting method. For high-speed applications we recommend larger diameters, fixed-fixed mounting, or our hollow and cooling-type ball screws.
Yes. We provide complete custom assemblies for Ball Screws — end journals, flange machining, wipers, lubrication fittings and nut housings per your drawings. As an OEM/ODM factory we can deliver a ready-to-install assembly.
MOQ depends on model and specification — standard models are available in small quantities, and volume orders receive preferential factory-direct pricing. Send us your required Nut-Rotating Ball Screw R2 Series model and quantity for a quote within 24 hours.
Key selection factors are: load, required accuracy, travel length, operating speed and mounting method. Send us your application details and our application engineers will provide a free selection proposal for Ball Screws with drawings and datasheets.
