Square Bore Spherical OD Ag Bearing, 1-1/2 ID X 4.095 (104mm) OD X 1.750 Width

The 851-SMAW211PPB6 AgSmart Square Bore Disc Harrow Bearing is a heavy-duty agricultural disc bearing designed for tough field conditions where dust, shock loads, and constant vibration are part of the job description. Featuring a 1-1/2" square bore with a spherical outer diameter, this bearing is built to fit common disc harrow housings while allowing slight misalignment during operation. The sealed design helps keep grease in and dirt out, extending service life and reducing maintenance. In short, it’s built to keep your disc harrow turning smoothly—because when bearings quit, field work usually does too.
