Technical Specifications
Ball Spline
SCREWTECH Automation
Offers SL/SO/RLSF ball spline series, with nominal shaft diameters 6–50 mm
The Gothic-arch 40° high-contact-angle design delivers rated loads over ten times those of same-diameter linear bushings, while enabling smooth linear motion and torque transmission—ideal for high-rigidity, high-precision rotary-linear drive applications.
Core Features
40° High Contact Angle · High Load Capacity
Gothic-arch 40° precision-ground grooves provide extremely high load capacity in both radial and torque directions. Rated load is over ten times that of same-diameter linear bushings, enabling a more compact design.
Zero Rotational Backlash · High Positioning Accuracy
2–4 ball circuits are preloaded to achieve zero rotational backlash and excellent positioning accuracy. Three precision grades (Standard / High / Precision) meet diverse needs.
High Sensitivity · Low Energy Loss
Specially designed ball contact points deliver high rigidity with superior sensitivity, reducing energy loss in transmission—ideal for high-speed, high-frequency reciprocating motion.
Non-Drop Balls · Easy Maintenance
Balls do not fall out when the outer cylinder separates from the spline shaft, making assembly, maintenance, and inspection easy. Solid, hollow, and special shaft types are supported.
Applications
Industrial Robots
Robot-arm swing axes, collaborative-robot joints, welding-machine shafts, automated loading/unloading machinery
