Single bearing replaces a four-component assembly

摘要

NKE Austria has developed a special bearing assembly for the cutter tine rotor of a power harrow manufactured by agricultural machinery specialist, Lemken. The new bearing unit replaces four separate compo nents: a standard deep groove ball bearing, a radial oil seal running on the inner race of a needle roller bearing and a felt seal in a metal housing. each of these four components had to be handled and fitted separately during the manufacture of the Zirkon 10 power harrow.
