The "Precision Ball Way" is a product that uses our proudly developed ultra-precision steel balls. It features simultaneous six-face NC grinding of the mounting reference surface and four rows of ball groove surfaces, resulting in excellent straightness accuracy of the guide block and improved bed mounting accuracy. It has characteristics such as four-direction equal rated load, high moment load, and a tube type, achieving long life, high rigidity, and high-speed operation. Additionally, it is well-known for its ease of alignment when assembling into machines, and it is widely used across various industries, similar to ball screws. In addition to this, we also offer a variety of products including the "Retainer-Type Precision Ball Way," which has no mutual friction between balls, as well as "Precision Miniature Ball Ways" and "Precision Ball Way Modules." 【Features】 ■ Uses ultra-precision steel balls ■ Excellent straightness accuracy of the guide block ■ Improved bed mounting accuracy *For more details, please refer to the PDF materials or feel free to contact us.
