Ball Splines

Winning performance in every situation

UMBRAGROUP ball splines transmit linear motion even at high speed and with minimal friction also under high torsional loads. They guarantee high reliability under varying operating conditions and have a predictable life expectancy. They resist radial displacements resulting from torque loads and require smaller forces to achieve axial displacement during torque transmission.


Due to their versatility and reliability, UMBRA ball splines are used in many critical applications for in-flight safety, such as helicopter motor couplings, translating drive shaft couplings, non-swiveling telescoping struts and leveling mechanism. A new patented   innovative ball spline architecture allows us to:

  • Minimize weight and size;
  • Maximize performance.
