Permissible radial shaft load
The output shaft runs in tapered roller bearings that permit high axial and radial forces.
The permissible radial load on the shaft is shown for an axial load of 0 N as a function of the distance from
the mounting flange to the point of load application.
The curve is based on B10 Bearing life (2000 hours or 12 000 000 shaft revolutions at 100 min
1
) at rated
output torque, when mineral-based hydraulic oil with a sufficient content of anti-wear additives, is used.
