  3. Applied to the input shaft center at n1B
  4. Applied to the output shaft center at n1B
  5. These values are measured by gearbox with ratio 5 (1-stage) at 1,500 rpm no loading.
    By lower ratio and/or higher RPM, the noise level could be 3 to 5 dB higher.

The maximum radial and axial loads on the output shaft of the gearbox depends on the design of the gearbox supporting bearings.
Apex Dynamics uses the extension straddle oversized ball bearing design. This can take heavy load from both axles

If radial force F2r is not exerted on the center of the ouput shaft X < ½ x L or X > ½ x L, the permitted radial and axial loads can be calculated by the position load factor Kb on the above diagram.
