of synthetic rubber very resistant to oil and to wear.

The nominal bearings lifetime is expressed in working hours according to the international bearings
lifetime calculations, and it depends on the applied load, temperature and speed. The maximum allowed
overhung load (N) acting at the middle of the output shaft (F in the sketch), for the different lifetimes
at different speeds, can be obtained from the table below for every motor frame size.
