We offer ball screw nuts for shafts with mounting dimensions in accordance with ISO 3408. All sizes are available in a number of different flange shapes with different load capacities depending on the number of ball turns. We offer ball screw nuts in single nut (four-point contact), double nut (two-point contact) and ETA+ formats. We only offer these larger sizes of ball screw drives with shafts designed to customer drawings. In order to provide a quotation, we require a sufficiently accurate drawing of the specified shaft. The nuts can be selected from the standard selection described here or custom made to customer requirements.

Customizable And Fast Delivery – Tailored Solutions with Rapid Turnaround:
Our Ball Screw is designed for maximum adaptability, ensuring seamless integration into diverse industrial applications. Customers can specify materials (such as hardened steel, stainless steel, or specialty alloys), dimensions, and tolerances to meet exact operational requirements. Whether for high-load machinery, precision medical devices, or aerospace applications, we provide tailored solutions that align with unique performance demands.
Despite the high level of customization, we maintain an impressive 14-day lead time—far faster than industry standards. Our streamlined production, combined with advanced CNC machining and quality control, allows us to deliver precision parts without delays. This rapid turnaround minimizes downtime, accelerates prototyping, and supports just-in-time manufacturing strategies.
Superior Performance – Precision, Speed, and Reliability for Demanding Applications:
Engineered for high-speed operation, our Ball Screw minimizes inertia and vibration, enabling smooth motion even at rapid feed rates. The precision-ground or rolled screw threads, combined with optimized ball circulation, reduce friction and heat generation, allowing consistent performance in CNC machines, industrial robots, and high-cycle automation systems.
Durability is a key factor—our design incorporates high-load bearings directly embedded in the nuts, improving rigidity and lifespan even under continuous heavy-duty use. This makes the system suitable for injection molding machines, heavy CNC equipment, and other high-stress industrial applications.
Single-nut ball screws are widely used in the following fields because of their compact structure, low cost and ability to meet medium precision and load requirements:
1. General industrial equipment
Automated production lines, packaging machinery, printing equipment.
2. CNC machine tools and processing equipment
Economic CNC machine tools, EDM machines.
3. Medical and laboratory equipment
Medical imaging equipment: Translation of CT machine slip ring brackets requires low noise and stability.
Laboratory instruments: Rely on the self-locking property of the screw (with brakes).
4. Automobiles and transportation
Automotive electronics: Electric window lifters, seat adjustments (dustproof seal design).
Rail transportation: Subway door switch transmission, which needs to pass vibration and durability tests.
Single-nut ball screws occupy the mainstream market in light and medium loads, medium and low speeds and conventional precision scenarios due to their cost-effectiveness.
The processing of ball screw products includes the following steps:
1. Material selection: Select high-quality metal materials, such as high-quality alloy steel, for the main part of the ball screw.
2. Turning: Use a lathe to turn the metal material. First, fix the metal material on the lathe and use a cutting tool to gradually cut the material into a cylindrical work piece. This step ensures that the ball screw has a precise diameter and length.
3. Screw thread processing: Screw thread processing is performed on the outer surface of the ball screw. This requires the use of a thread tool to cut the thread line onto the ball screw so that it can be matched with other equipment.
4. Steel ball processing: Make steel balls of suitable size for rolling movement between the ball screw and the slider. Steel balls are usually made of metal materials and are precisely sized through processing processes such as grinding.
5. Assembly: Assemble the various components of the ball screw. It mainly includes placing the ball screw into the guide rail and ensuring that the steel ball is correctly assembled into the raceway between the ball screw and the slider.
6. Debugging and quality inspection: After assembly, the ball screw needs to be debugged and quality inspected. This includes checking the rolling smoothness, measuring the accuracy and size of the screw, and verifying the quality and performance of the entire ball screw system.
7. Surface treatment: As needed, the ball screw can be surface treated, such as chrome plating, blackening, etc., to improve its wear resistance and corrosion resistance.
