Highlights
High-precision
integration
The screw threads are Gothic threads. After preload is applied, the axial clearance in the rotational direction is zero, achieving high-precision positioning.
Based on rotary motion of ball screws and axial motion of the spline nuts, the ball spline and ball screw can move in linear, rotational, or helix mode, with high product integration.
Lightweight
and easy to use
The integrated design of the nut and support bearing ensures that steel balls will not fall even if the spline nut is pulled out of the spline shaft.
The precision ball spline is lightweight and smaller in size, requiring smaller installation space.
Heavy load
Consistent groove curvature, pressure angle, and out of roughness on the surface of working raceways ensure the high load and high rated dynamic load.
Low noise
The end bracket backflow design and the high-stiffness and wear-resistant materials effectively reduce torque fluctuations and friction, improve sound quality, and facilitate smooth motion between components.
High stiffness
The precision screw support bearing and precision spline support bearing are designed with a 45 ° contact angle and withstand the same axial and radial forces, providing high axial and radial stiffness.
Precision ball spline and Ball screw
- Imported materials and heat treatment processes can result in good precision retention.
- The axial clearance is 0, which allows for high-precision positioning.
- The innovative design prevents no-load steel balls from circulating around the perimeter, and the outer diameter of the spline nut is smaller, requiring smaller installation space.
- The nut and the support bearing are integrated. The nut is lighter and smaller, achieving a miniaturized, lightweight, and highly responsive design.
