SYDFE1-2X/045R-PPA12N00-0000-B0X0XXX

The SYDFE1-2X/045R-PPA12N00-0000-B0X0XXX is produced by Bosch Rexroth for the SYD Hydraulic Control Systems series and serves as a variable delivery element in automated hydraulic circuits. A displacement of 45 cm³ sets the volume of fluid moved per revolution, guiding flow calculations for servo-controlled loops. The shaft turns clockwise, matching drive trains that require right-hand rotation. Permitted speed spans from 250 rpm to 3100 rpm so the unit accommodates both low-speed positioning and high-speed duty. At full displacement the pump can supply 117 l/min, a value that supports medium-capacity actuators. Operating pressure tops out at 280 bar, establishing the working limit for proportional pressure regulation. With this pressure the machine delivers up to 55 kW of hydraulic power and 200 Nm of torque, indicating the mechanical energy that can be transferred. Mineral oil in the HL or HLP category is specified as the hydraulic medium to maintain lubrication and material compatibility under continuous service.

The design omits a through-drive, so the primary shaft is the sole power take-off and no additional pump stages can be piggybacked. A housing filling quantity of 1.0 l keeps internal components submerged, ensuring immediate oil supply at startup. The mass of 26 kg affects support structure choice and adds inertia that can damp external vibration. Rotational inertia of 0.0033 kg·m² must be included when sizing the prime mover for rapid acceleration cycles. Axial shaft force may reach 1500 N without overloading the bearing set, allowing direct coupling to thrust-loaded mechanisms. The same 1500 N limit applies to radial force, defining permissible belt pull or gear mesh pressure on the shaft journal. These load capacities, together with the sealed housing and defined oil reserve, allow the unit to maintain stable performance in closed-loop hydraulic control installations.
