Ball splines for the defense sector

Splined shafts with recirculating ball: winning performance in every situation

The Splined shafts with recirculating ball manufactured by UMBRAGROUP 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.

The advantages of the UMBRAGROUP ball splines

Due to their versatility and reliability, UMBRAGROUP 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.
