Ball Splines

Ball spline systems feature high speed, anti-friction linear motion under high torsional loads and have high reliability under varying operating conditions and predictable life expectancy. They resist radial displacements resulting from torque loads and require smaller forces to achieve axial displacement of the spline member while transmitting torque. Ball Spline systems have application versatility such as:

• Helicopter motor couplings
• Translating drive shaft couplings
• Non-swivelling telescoping struts
• Honing machine
• Drill press spindles
• Robot and remote handling machines

Benefits of Ball Spline systems include:

• High speed, anti-friction linear motion under high torsional loads
• Anti-friction linear travel by ball recirculation
• Resistance to radial displacement resulting from torque loads
• Smaller force required to reach axial displacement of spline members while transmitting torque
• High reliability under varying operating conditions and predictable life expectancy
• Minimal lash resulting from wear and elimination of stick-slip
• Minimised friction reduces heat, preventing seizure
• Custom machined keyways are available for both inner and outer race
