Bevel gears 66/4 - shaft numbering:

The gear ratio and configuration are set relative to the input shaft (n1). For ease of reference, it is always shown at the bottom in the drawings. The subsequent shafts (output - n2) are numbered clockwise. Please note this when ordering.

Bevel gears 66/4  - radial and axial load:

FR = max. 150 N - radial load, this is a load acting perpendicular to the shaft/axis

F = max. 15 N - axial load, this is a load acting on the shaft/axis

T = max. 4 Nm - output torque.

When ordering, specify whether the axial load will be caused by pulling or pushing.

Radial and axial loads are generated by mechanical elements with which the gear unit works. They can be caused, for example, by pulling belt drives, acceleration, deceleration, misalignment of the structure, vibrations, shocks, etc.
