Hello folks..

I work as a representative of a German manufacturing company in the province of Shandong China, manufacturing components for the aviations industries, from PSRU’s, specialized engines components and other aviations items for the export market. The company has released 5 type of PSRU all of them reversed engineered to a superior standard of materials and engineering.

PSRU Aero-11 Propeller Speed Reduction (2.55) Unit with helical gears (40 CR) supported by four ball-bearing races. The output shaft in an isostatic configuration with an oblique two crown sphere bearing. Clutch engages: 1900-2100 rpm. (sold separately ) Gears are EN39B case hardened to 60R, alloy case is CC601 heat treated to T6, output shaft is 4140. Weight: 9kg (20lbs). Rated up to 130 hp at 6500 rpm, and easily adaptable to any engine. Connection from clutch to primary gear through a grooved hub, made from 7075-T6 with hard anodized surface. Bell housings available for Suzuki, Webber 750 Ergal mass centrifugal dragging hub with hard oxide surfacing. Clutch shoes are of the sintered type with a bonded material high friction coefficient. FOB China USD 740.00 (minimum order)


PSRU Aero 22 Is a single reduction gear drive (2.34) utilizing two helical cut gears mounted on shafting which is supported by ball bearings at each end. The torque is transmitted by a fully machined shaft which is driven by an extension of the flywheel bolts. This shaft drives a 3 bolt "star" assembly one piece machined to the shaft. The engine output torque is then passed to a non-metallic assembly Centaflex type (held by three bolts) In this assembly, that non-metallic unit is referred to as the torsional vibration damper. These gearboxes were designed in 2008 for aviation conversion of 2 and 4-stroke engines. Recommended for up to 170HP engines. It is possible to use these gearboxes for both (tractor and pusher) layouts, install it up, down and any degrees left or right on the bell housing. The body consists of 2 bolted down parts: 1) gearbox with the gear and oil inside and damper housing ,mount plate (bell housing) and crank-damper coupler. The gearbox life-time is 1000-2500 hours (depends on the engine power and the prop moment of inertia). Gears are EN39B case hardened to 60R, alloy case is CC601 heat treated to T6, output shaft is 4140.Bell housings available for Suzuki, Subaru, Webber 750 FOB China USD 980.00 (minimum order )

PSRU AeroFlight33 AeroFlight redrives are a self-contained, oil bath, helical cut gear to gear, prop speed reduction unit. 2.2, to 1 ratios and are Centaflex driven for harmonics. Rotation is counterclockwise and prop flanges come in 4", SAE 1 & 2 with drive lugs. This box are offered in 190hp versions for Subaru EJ 25 SOHC and DOHC. Gears are EN39B case hardened to 60R, alloy case is CC601 heat treated to T6, output shaft is 4140.Bell housings available for EJ series Subaru FOB China USD 1200.00 (minimum order )

All PSRU’s are entirely made by a German engineering company based in the Province of Shandon China ,specializing in the manufacturing of Aircraft components for the international market. All reduction boxes are fully Dyno tested with TUV and ISO certificates and made under the strict supervisions of German technicians and engineers. All PSRU are fully warranted for a period of 12 Months from the moment of operational installation.

For more information please don’t hesitate to ask any question, all questions and emails will be promptly answered alternatively follow this tread, very well discussed
