CrossLube With over 1000 acres of cash crops on the line, bearing fallure is not an option, A tractor during harvest tlrne Just can't fail. Miles of farmland must be economically processed. But, condilions can be very tough on mechantcal components. including bearings. Dust and crop dbris constantly bombard bearings with contaminants. Crisscrossing rugged, uneven fields cr驢tes high impact loads on critical components. In particular, tractor steer axle king pin assemblies can be subjected to heavy abuse, tn addition to impact loads, steering correclions create friction induced wear in king pin bearings. In fact. thse converging l詩ments had been inducing repeated bearing f allure in the king pin assembly of a steer axle for a major line of large agricultural tractors. C Engineered Solutions for the Most Rugged Bearing Challenges RBC limintes pr颩matur bearing failure for applications with high thrust loads in dirty, contaminated environments. What The Customer Needs: C engineers The tractor producer approached ts supplier of steer axles for a solution, fast. Pr鮩matur bearing failure was rapidly developing into a trend. Good customer relations are precious. Wananty cosls can get out of control. RBC engineers, known lor innovative solutions for the most rugged bearing applications, were asked by the axle supplier to look at the problem. alyzing the problem. BEARINGS Our engineers examined the existing king pin assembly that utilized taper rolier bearings. The bearings were pressed into upper and lower positions on each end ol the axle housing. The king pins were fixed to steering knuckle assemblies. sharing a common centerline with the taper tlier bearings. King pin rotation within the taper rolier bearings provided proper location of steering components as well as free rotation during steering maneuvers. Fax (609) 882-5533 w/w rbcbearings.com
