Ball Splines

Thomson precision ball spline systems feature high speed, anti-friction linear motion under high torsional loads. They have high reliability under varying operating conditions and predictable life expectancy. Thomson precision ball splines resist radial displacements resulting from torque loads and require smaller forces to achieve axial displacement of the spline member while transmitting torque. They have application versatility such as helicopter motor couplings, translating drive shaft couplings, non-swiveling telescoping struts, and much more.

Overview

Ball Splines Highlights

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
Minimized friction reduces heat, preventing seizure
Custom machined keyways are available for both inner and outer race
Application versatility - helicopter rotor coupling; translating drive shaft coupling; non-swiveling telescoping struts; honing machine and drill press spindles; workhead and table ways; robot and remote handling machines
