LIEBHERR PLANETARY SATELLITE GEAR FOR SLEWING REDUCER

Ask about product

The planetary satellite gear (satellite) for the slewing reducer of Liebherr construction machinery superstructure — a critical component of the planetary gearset within the upper carriage rotation mechanism. LIDOS designations SAT 225/220, SAT 225/229 directly identify the slewing reducer product series (Schwenkgetriebe / Drehwerksgetriebe). This is a hardened helical spur gear machined from case-hardened steel, equipped with a pressed-in needle roller bearing that engages with the satellite cage pin. It operates immersed in transmission oil within the slewing reducer housing, enduring high cyclic loading stresses during each rotational movement of the superstructure. Replacement must be performed as a complete set of 3-4 units from one planetary stage — mixed installation of new and worn satellites causes uneven load distribution and premature failure of replacement components.
