Max. pressure Max inlet pressure cont. OMSW Max return pressure with drain line Intermittent operation: the permissible values may occur for max. 10% of every minute. Peak load: the permissible values may occur for maximum 1% of every minute. Note: For max. permissible combination of flow and pressure, see function diagram for actual motor. Max. permissible shaft seal pressure OMSW with check valves The pressure on the shaft seal never exceeds pressure in the return line Figure 4 OMSW with check valves OMSW with drain connection Use of the drain connection: The shaft seal pressure equals...

Pressure drop in motor Figure 7 Pressure Drop in OMSW The curve applies to an unloaded motor shaft and an oil viscosity of 35 mm2/s [165 SUS] Oil flow in drain line The table below shows the max. oil flow in the drain line at a return pressure less than 5-10 bar [75-150 psi].

Permissible shaft load for OMSW 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.
