The "A Series" is a ball screw designed with ball diameters and circulation numbers suitable for the nut body diameter and shaft diameter, taking into account the rated load. By compacting the outer diameter of the nut and the flange section, it contributes to the miniaturization of equipment and the expansion of space within the device. We have achieved approximately 30% miniaturization and a maximum weight reduction of about 50% compared to our previous models. Furthermore, in response to recent automation needs and high-speed requirements, we have significantly increased the maximum rotational speed and DN value, keeping pace with the performance of high-performance motors. 【Features】 ■ Compact outer diameter of the nut and flange section ■ Contributes to the miniaturization of equipment and the expansion of space within the device ■ Achieved approximately 30% miniaturization and a maximum weight reduction of about 50% compared to our previous models ■ Significantly increased maximum rotational speed and DN value ■ Adopted ball diameters and circulation numbers suitable for the nut body diameter and shaft diameter *For more details, please refer to the PDF document or feel free to contact us.
It is possible to select an optimal size without waste from a rich variety of screw shaft outer diameters and leads!
The "G Series" is a tube-type ball screw characterized by a variety of shaft diameters and leads. It allows for precise selection of accuracy from a wide range of accuracy grades, making it suitable for positioning accuracy in general FA equipment. Please feel free to contact us when you need assistance. 【Features】 ■ Various shaft diameters ■ Various leads ■ Positioning applications ■ Transport applications *For more details, please refer to the PDF materials or feel free to contact us.
Compact nut shape in the smallest class in the industry! Ideal for precision small feed machinery.
The "D Series" is a product that adopts a ball circulation method using a deflector, allowing for smaller nut dimensions for ball screws. This achieves one of the smallest nut shapes in the industry. The lead ranges from 1 to 4 mm, making it suitable for machinery that requires precise small feed and positioning. 【Features】 ■ Compact nut shape among the smallest in the industry ■ Ideal for machinery requiring precise small feed *For more details, please refer to the PDF document or feel free to contact us.
The adoption of multiple screws has achieved a compact nut design! The high lead configuration is suitable for high-speed transport.
The "H Series" is a ball screw with an end cap design that employs a high lead of 1 to 3 times the outer diameter of the screw shaft. This allows for high-speed feeding even at low rotations, effectively reducing vibration, noise, and heat generation. To address the tendency for the nut shape to become elongated with high leads, a multi-start screw design has been implemented, achieving a compact nut length and an increase in rated specifications. 【Features】 ■ High lead of 1 to 3 times the outer diameter of the screw shaft ■ High-speed feeding possible even at low rotations ■ Effective in reducing vibration, noise, and heat generation ■ Achieves a compact nut length and an increase in rated specifications *For more details, please refer to the PDF document or feel free to contact us.
