Rolling Spline

Our Rolling Spline series is a high-performance linear motion transmission solution engineered to deliver simultaneous high-precision linear sliding and reliable torque transmission, combining the advantages of rolling friction technology and precision mechanical design. As a core component for complex motion control systems, our rolling splines eliminate the stick-slip effect of traditional sliding splines, achieving ultra-smooth motion, exceptional rigidity, and long service life for demanding industrial applications. We offer three specialized product lines to cover diverse operational needs:GJA Type, GJR Type, and Ball Screw Spline, each tailored to unique performance and application requirements.

Core Product Features

• Dual-Function Motion Transmission: Enables seamless integration of high-precision linear reciprocating motion and high-torque rotary transmission in a single component, simplifying mechanical structure and reducing installation space.

• Ultra-Low Friction & High Efficiency: Adopts precision rolling ball contact design instead of sliding friction, achieving up to 90%+ transmission efficiency, drastically reducing driving torque, energy consumption, and wear for long-term stable operation.

• Exceptional Rigidity & Load Capacity: Manufactured from high-hardness, wear-resistant alloy steel with advanced heat treatment, our rolling splines withstand heavy radial, axial, and torsional loads, with heavy-duty variants engineered for high-intensity industrial operations.

• High Precision & Repeatability: Tight manufacturing tolerances and optimized ball circulation systems ensure minimal backlash, outstanding positioning accuracy, and consistent repeatability, ideal for high-precision motion control scenarios.

Wide Application Scenarios

Our rolling splines are critical components for complex motion control systems across global industrial sectors, powering equipment such as:

• Industrial robots, robotic arms, and multi-axis CNC machine tools for precision manufacturing

• Automated assembly lines, packaging machinery, and material handling systems in factory automation

• Semiconductor manufacturing equipment, medical devices, and optical instruments for ultra-precision positioning

• Aerospace, automotive production lines, and heavy-duty industrial machinery for high-torque, high-load operations

• 3D printing, laser processing equipment, and testing instruments for general automation applications

• Specialized machinery requiring simultaneous linear and rotary motion, such as pick-and-place systems and automated tool changers

Whether you need general-purpose GJA Type rolling splines for standard automation, heavy-duty GJR Type variants for extreme industrial conditions, or integrated Ball Screw Spline solutions for complex multi-axis motion systems, our comprehensive Rolling Spline series provides tailored, high-performance solutions to elevate the efficiency, precision, and reliability of your machinery.
