Pumping principle Continuous tooth contact reduces operating noise:A non-involute rounded tooth profile, combined with helicalgearing, forms the heart of the SILENCE PLUS. Thanks topermanent tooth contact, the hydraulic fluid is transportedalmost continuously and noiselessly. The possibility ofnoise developing from trapped oil between the tooth flanksis prevented in the first place.A hydrostatic bearing ensures long service life:The high performance and long service life of the SILENCEPLUS is due to a Rexroth patented solution: Hydrostaticgrooves provide wear-free compensation for the internalaxial forces generated in the helical gearing - even at pres-sures up to 280 bar.
