Series 90 Axial Piston Pumps Technical Information System design parameters sHaft LoaDs Normal bearing life in B 10 hours is shown in the table below. The figures reflect a continuous differential pressure of 240 bar [3500 psi], 1800 min -1 (rpm) shaft speed, maximum displacement, and no external shaft side load. The data is based on a 50% forward, 50% reverse duty cycle, standard charge pump size, and standard charge pressure. Series 90 pumps are designed with bearings that can accept external radial and thrust loads. The external radial shaft load limits are a function of the load position and orientation, and the operating conditions of the unit. The maximum allowable radial load (Re), is based on the maximum external moment (Me), and the distance (L) from the mounting flange to the load. It may be determined using the table and formula below. Thrust (axial) load limits are also shown. 14 520L0603 • Rev FC • August 2008 Bearing life frame size bearing life – b 10 hrs 42 18 060 55 22 090 75 22 970 100 22 670 130 17 990 180 16 150 250 12 020 Re = me / L All external shaft loads affect bearing life. In applications with external shaft loads, 180˚Re Pump swashplate minimize the impact by positioning the load at 90° or 270° as shown in the figure. Contact your Sauer-Danfoss representative for an evaluation of unit bearing life if: • continuously applied external loads exceed 25 % of the maximum allowable radial load (Re). • the pump swashplate is positioned on one side of center all or most of the time. • the unit bearing life (B 10) is critical. Sauer-Danfoss recommends tapered input shafts or clamp-type couplings for applications with radial shaft loads.
